Profile
Rock engineering as well as rock mechanics is a truly interdisciplinary subject, with applications in geology and geophysics, mining, petroleum, and civil engineering. It relates to energy recovery and development, construction of underground spaces for transportation, water resources and defense facilities, prediction of earthquakes, and many other activities of greatest importance. Practitioners in this field have made important contributions in mining and civil engineering possible by accumulated practical experience, engineering judgment and often by a trial-and-error approach. In essence, the rock engineering practice has traditionally been an art rather than an engineering science. Despite this fact, the rock engineering science has been advanced by the devoted efforts of many scientist, researchers and engineers. Today, many workers in the rock engineering field tend to use comprehensive numerical modeling to study and solve complex issues. Although these models are powerful, it is difficult and rather impossible to obtain the necessary input data. It should be emphasized that field observations and measurements could play an important role in solving the issues. It has been pointed out that there is a big gap between theories and practice. 1. Grouting system in rock masses and backfilling system in pipe jacking. 2. Estimation of initial stress conditions using AE. 3. Fully mechanized and automated rock excavation system in surface mines. 4. Stabilization of ground with mud slurry in pipe-jacking system. 5. Flow and solidification behaviors of fly-ash slurry in backfilling system.

    近年、廃棄物最終処分場の処分容量の拡大が喫緊の課題となっており、その有力な解決手段として、一施設当たりの処分容量を格段に大きくできる海面埋立地を処分場として用いる海面処分方式が挙げられる。この海面処分方式の最も重要な機能は、廃棄物保有水の漏出を防ぐ遮水機能であり、遮水壁の築造のために地盤改良工法が用いられる。このような廃棄物最終処分場の建設や土壌汚染対策等に対応する環境分野、また地震や洪水等に対応を迫られている防災分野においては、構造物の基礎、土留・山留、液状化防止対策、地中連続遮水壁等の構築を目的として、強度や透水係数が深さ方向に均一で高品質、かつ経済的な地中連続遮水壁の築造が要求されている。
    このような背景から、筆者は地中連続遮水壁の築造に供する新たな地盤掘削改良装置を開発し実用化に至っている。すなわち、駆動部にチェーンソータイプの機体を垂直に搭載し、チェーンを上下方向に回転させながら地中連続遮水壁を造成するチェーンソー方式であり、また汎用杭打機に搭載可能である。さらに、セメント等の改良材を地中に供給しながら、原地盤の軟弱土と改良材を強制的に撹拌混合して固化・強化するアースオーガ方式と同様に機体を出し入れしつつ、多様な形式の施工が容易な装置の新規開発に取り組み、新たな地盤掘削改良装置;チェーンコンベアカッター(略称;CCC)を完成させている。本論文は、この装置の企画・設計から実用機の開発および適用までの経緯を、現場での試験施工や実施工結果、数値解析等により検討を加えて取りまとめたものである。

    In order to find the relationship between the shaft lining stability and the coal extraction operation, a 3D numerical model of strata layers and shaft lining was established for simulating the influence of coal extraction operation on shaft lining. Certain factors including mining depth, safety pillar width, mining width and mining height were taken as the influence factors in the simulation. The results indicated that the coal extraction could lead to the initiation of the failure in the aquifer and rock layers. As the mining depth increases, the shear strain increment in aquifer becomes small. In this case, the distance between mining panel and aquifer should be larger than 220 m and the safety pillar width should not less than 70 m. The maximum principal stress in aquifer had a little relation to mining operations. The mining panel width should not exceed 50 m without any support.

    Soil erosion is one of the most important problems in Indonesia coal mining reclamation area because located in tropical areas which has high average of rainfall. Severe soil erosion leads to the unsuccessful reclamation progress in the post mine surface due to impact on steep slope and limit of seedling establishment. Considering the impact of soil erosion in mining activities, Indonesian government had issued several regulations related to erosion control. Soil erodibility is one of the main factors controlling soil erosion. It will determine amount of soil loss and total sediment. Estimation of soil erodibility aims to determine the susceptibility of soil to be eroded by water. The estimation considers soil texture, percentage of organic matter, soil structure and soil permeability. This study was integration between field work to collect soil sample, soil laboratory analysis, soil erodibility analysis using erodibility equation Wischmeier and Smith (1978) and analysis to predict soil erosion/ annual total soil loss. The results show that soil erodibility in study area was calculated to range from 0.091 to 0.142 tons ha h/ha/MJ/mm and soil erodibility of the study area was categorized as very low and low. There are strong relationships between soil erodibility and soil erosion but the correlation was not fully linier due to other factors controlling soil erosion / annual total soil loss.

    In Japan, pipe jacking has been firmly established as a special method for the construction of underground pipelines.
    Recent technological developments have produced successful methods for the stabilization of unstable strata by employing lubricant around the pipes. The contraction of the lubricant volume after injection into the over-cutting area needs to be reduced for slurry pipe jacking. Moreover, pressurized lubricant functions as an important support in the mitigation of overburden pressure. Therefore most of the underground deformations caused by the pipe jacking construction may be caused by changing stress and strain conditions over the course of construction. Moreover, lubrication can effectively reduce the needed thrust if a discrete layer of lubricant is maintained between the pipe and the excavated soil. The lower frictional force that lubrication enables allows larger jacking lengths to be achieved. That is why the discussion of appropriate lubricants and injection methods, etc. in preparation for such changes is inevitable. From this point of view, the new backfilling material can be developed for several kinds of soil conditions.

    In underground coal mines, floor heave is a major problem that is caused by groundwater, high strata stress and weak floors. Controlling the stability of the roadways is the key to maintaining the safety and efficiency of underground mining. Appropriate cement grouting is an effective and attractive floor reinforcement technique that can control excessive floor heave and closure. The cement grouting also reduces the permeability of the rock mass and consequently controls the movement of groundwater into the roadway. Injecting cement grout into roadway floors provides a more uniform reinforcement throughout the floor. It may even be possible to reinforce an extremely fractured floor. In this respect, this technique is superior to floor bolting/doweling. This technique may be performed either as a pre- or post- development reinforcement. It is very difficult, however, to reinforce a floor that is not heavily fractured by the injection technique. Therefore, before floor injection, floor blasting is performed in order to create an adequate number of fractures in the floor. Fracturing by blasting also relieves and improves stress conditions in the floor. From this point of view, the behavior of grouting injection for floor reinforcement technique is discussed.

    Generally, grouting in dam construction is the construction method that soil voids and crack around borehole is filled by pressurized injection of grouting material such as cement and permeability or mechanical characteristics of rock mass is improved.
    It was previously mentioned that backfilling material plays an important role as a support against overburden pressure after finishing construction. Therefore most of the underground deformations caused by the injection may be caused by changing the condition of surrounding rock masses and numbers of cracks. That is why the discussion of appropriate injection methods, etc. in preparation for such changes is inevitable. From this point of view, the new backfilling material can be developed for several kinds of soil conditions in this paper.

    In recent years, many waste disposal sites have been conventionally constructed on land in Japan. However, there are limitations to constructing these sites on land. Thus, construction of the disposal sites by reclamation of nearby seashore has been conducted. Although injection material is required to make the established offshore structure, it has high mobility, and does not bleed, etc. Therefore, an injection material which uses a material mixture of the surface-active agent with flyash has been developed. Usage of flyash instead of cement leads to improved mobility, reduced construction cost and so on.
    Considering these points, in order to clarify to at which degree the contents of surfactant affects the properties of the injected flyash mixture into the joints of steel sheet pile for offshore structures, different combinations of flyash, surfactant and

    A large amount of waste is produced by preparation plants. The properties of the waste vary depending on the minera- logical contents of the mother rock in which the coal is embedded. The waste quality depends on the method of mining and cleaning. The waste mainly consists of clays, quartz, carbonaceous materials, mica, pyrites, and so on. About 80% of coal-ash is now utilized and the remainder is disposed of at disposal sites. However, the life span of disposal sites is limited, and it is difficult to find new disposal sites. It is therefore requested that the percentage of utilized flyash be increased in all applicable fields in Japan. Thus, it is very desirable that cement supplemented with flyash be used as injection material for natural/artificial openings. With this perspective in mind, we attempt to clarify how much the size and shape of the flyash affects the properties of the injection mixture by way of an injection test.

    Tunnels in an urban area, in many cases, are constructed in soft ground which contains underground water, near existing facilities and structures. Structural stability for the tunnel and also the nearby structures and facilities is vital in this kind of work. Slurry pipe jacking was firmly established as a special method for the non-disruptive construction of underground pipelines of sewage systems. This method utilizes mud slurry that is formed around the pipes in order to stabilize the surrounding soil. In the pipe roof method the tubing elements that are constructed by slurry pipe jacking are near each other longitudinally, and create a rigid and stable lining before the excavation of the main tunnel. This paper discusses the application of a slurry pipe jacking system on the pipe roof method by means of numerical analysis. Because of the rigid behavior of the lining, the results show little subsidence, making this method a reliable method of constructing large tunnels with small cover in an urban area.

    To improve the resources’ recovery ratio and the economic benefits of surface
    coal mines, we present a residual coal extraction technology from final end-walls
    with highwall mining system in China. Based on Mark–Bieniawski formula and
    tributary area theory, the evaluation methodology of highwall mining parameters
    under the thick cover was given. Furthermore, the pillar design chart in the
    highwall mining system under the thick cover was also concluded. In order to
    examine the rationality of the pillar design with the presented methodology,
    numerical simulation was also carried out. The outcome shows that it will require
    a larger pillar width with the thickening of the cover; hence, the recovery ratio will
    decrease correspondingly. To improve coal recovery ratio, the backfilling
    technology should be considered under the thick cover. According to twodimension
    numerical simulation results, the calculated methodology for pillar
    stability of highwall mining system under the thick cover presented in this article
    is acceptable. It also found that keeping the pillar width-to-height ratio above 1 is
    a key measure to maintain the pillar stable and integral under the thick cover.
    Meanwhile, it can be concluded that the bigger safety factor is demanded for roof
    of openings under much thicker cover and higher stress ratio. In other words, the
    highwall mining system is feasible to extract the residual coal around end-walls in
    Chinese surface coal mines. Thus, not only coal recovery ratio can be improved
    but also can increase the production life of surface coal mines in China.

    In Japan when urban infrastructures need to be constructed, the difficulty of utilizing the ground or shallow strata will lead to a more frequent use of the deep strata. The common construction methods are open-cut, pipe jacking, and shield methods. In recent years, a new pipe jacking method has been established that can be adapted to 20 m below the ground or more. Using this method, the drivage machine and the jacking pipe continue to move an underground until the com- pletion of the driving. Therefore an over-cutting area (so-called tail-void) must be formed to lower the friction between the ground and the pipe. The tail-void is filled with lubrications. However, because the stress release from the ground continues to advance when the tail-void is formed, hence there are some challenges required to cope with the stability of the surrounding ground. In order to utilize the pipe jacking method in the deeper strata layers, the theory, analysis and installation of tail-void have to be systemized, and such systematic data must be stored. Therefore, the conditions of tail-void in the deep pipe jacking method are discussed using numerical analyses.

    There are many earthquakes in Japan. If a large earthquake were to occur, it is necessary to consider how pipelines such as: gas, sewage, telecommunications, and so on are restored quickly. At that time, damaged gas pipelines are very dan- gerous because fire in large areas could be caused by the leakage of gas from the damaged pipeline. Accordingly, it is necessary for gas companies to stop the supply of gas to houses over a large area. Once the gas supply is stopped, there is a considerable amount of time to repair the pipelines over the area. For this reason, a quick method for restoring damaged gas pipelines would be useful after an earthquake. Recently, we have been developing new flash setting mate- rial for the damaged gas pipeline by an injection into the house connection of gas when the gas supply is stopped quickly in an emergency. From these points of view, in order to clarify to what degree the contents of flash settling ma- terial affect the properties of the injected fly ash mixture causing heavy damage to the gas pipeline in an earthquake, different combinations of fly ash, chemical agents and water were considered in several experiments.

    Buried pipelines that have sagged can result in damage to welded joints, disconnections and so on. Performance can also be affected with stagnation or stoppage of flow, which can lead to major secondary problems, such as caved-in roads or effluent leakage. To overcome these problems, various methods have been proposed and used for the restoration of flow performance and fixing damaged sections of underground pipelines without the need for excavation. However, there are not many methods available that do not require excavation for repairing reduced flow performance and stoppages, or pipeline damage caused by sagging, which is thought to be the major contributor to this type of damage. The authors provide a report on construction methods and examples that do not require excavation, but instead use a system of grouting for the ground, surrounding the buried pipeline, to aid in the repair of the pipeline position, which can actually improve the surrounding foundations.

    The presence of water and oxygen are some of the important factors influencing the oxidation rate of sulfide minerals within overburden dumps. In the overburden dumps, the availability of water and oxygen is strongly controlled by the physical structure of the dump, as well as the surface climate and geochemical reaction within the dump. In this study, made up of a series of field investigations, physical and geochemical laboratory characterizations were conducted in order to evaluate the internal physical structure and geochemical characteristics of coal mine overburden dumps. As the result of a series of analysis, alternate geochemical characteristics may control the acidification-neutralization reaction of infiltrated water, the precipitation of secondary minerals and may subsequently determine the quality of the overburden dump drainage. The internal structure formed and the spatial heterogeneity of geochemical characteristics in the overburden dumps controls the acid drainage inhibition process within the dumps.

    Based on experimental and numerical investigations, we focused on a U.G.S. (Under Ground Scope) chemical grouting method which can actually improve the pipeline surrounding foundation to solve pipeline saggy damage. As is known, saggy pipelines can result in the destruction of welded joints, disconnections and shear fractures, and can also lead to more serious accidents, such as caved-in roads or effluent leakage. However, this method can deal with these difficulties successfully.
    Based on the experimental results, a solution-form injection material can lift up the ground effectively, using less total solution amount than suspension-form injection materials. Therefore, a suspension-form injection material with a shorter gel time is more suitable for a U.G.S. method, making it more effective to remove pipelines.
    The discussion results of some patterns of injection tests in a laboratory setting that were carried out in order to find the relationship between the behavior of the grouting material and the deformation of the soil were obtained. According to the experimental results, it is considered that the material can be injected into a foundation by fracture grouting if the permeation coefficient is lower than 1.00×10-3 mm/s. The situation was analyzed by using two-dimension FEM (Finite Element Method) analysis software Phase2 and the analysis result proposes that the real data and simulation data are nearly the same in impermeable soil. Furthermore, even if the construction object is permeable soil, we can also make it impermeable soil by grouting in two phases: soil improvement grouting and restoration grouting.

    A large amount of waste is produced by the preparation plant. The properties of the waste varies, dependent on the mineralogical contents of the mother rock in which the coal is embedded. The waste quality depends on the method of mining and cleaning. The waste mainly consists of clays, quartz, carbonaceous materials, mica, pyrites, and so on. About 80% of coal-ash is now utilized and the remaining is disposed of at disposal sites. However, the life span of the disposal site is limited, and it is difficult to find new disposal sites. It is therefore requested that the percentage of utilization of flyash be increased in every field in Japan. So, it is very desirable that cement with flyash added be applied as the injection material for natural/artificial openings.
    From these points of view, in order to clarify to what degree the contents of surfactant affects the properties of the injected flyash mixture in slurry pipe jacking, different combinations of flyash, surfactant and water were considered by means of several experiments.

    In situ stress measurement is not well accepted yet in Indonesia due to the unavailability of technology, high costs and because it is impractical in remote regions. Alternatively, the Kaiser effect of acoustic emission (AE) can be used as a method for determining the stress-state at depth, without creating induced stress and is practical in remote areas. This paper is focused on the development of the AE test. The research has started to study the phenomenon of stress memory in a rock sample, the factors influencing the phenomenon, and finally, to determine the in situ stresses around underground excavations by applying the AE method. It is expected that knowledge in gaining the most important input parameters for maintaining the stability of underground excavations can be well understood and be reliably conducted at a reasonable cost.

    In recent years, there has been an increased resort to box-jacking as a method for constructing underground utilities and infrastructure, as it avoids the on-street disruption in urban areas. An accurate estimation of the total jacking force requirements during a drive is a key design consideration for determining the capacity of box culverts, the placement of interjack stations, and the overall efficacy of the box-jacking project. Nevertheless, predicting the total jacking force is complicated by site geology, lubrication performance, work stoppages, deviations in alignment, and the imperfect calculation model. This study introduces a Bayesian framework that predicts jacking forces by using pipe-jacking parameters updated from field observations. The proposed framework was applied in two box-jacking monitoring projects in Japan, and the forecasts were appraised though comparison to predictions determined using classical optimization technique, namely particle swarm optimization. The results show that predictions of jacking forces based on prior hypotheses resulted in a significant overestimation of the monitored jacking forces for both drives. In contrast, the proposed framework provided excellent forecasts, highlighting the limitations of prescriptive design approaches in capturing complex geotechnical conditions during tunnelling and the importance of robust back-analysis techniques. Furthermore, the results also show that Bayesian updating coupled with a sliding window approach is a very effective option when there are considerable fluctuations in jacking force development.

    <p>Underground Coal Gasification (UCG) is a promising process for recovering energy from potential underground coal resources as combustible gases such as hydrogen and carbon monoxide. The gasification process that occurs underground is an invisible phenomenon, and the temperature in the underground gasification reaction zone can be over 1,000 °C. Therefore, the visualization/monitoring of the gasification area of UCG plays an important role in the development of a highly efficient, safe , and low environmental impact UCG system. This article reviews the possibility of monitoring high-temperature gasification reaction zones in UCG using Acoustic Emission (AE) technique. AE monitoring can be used as a real time monitoring technique because AE can be detected at the same time when the cracks occur due to the gasification, indicating that it gives an advance warning immediately if the extensive damage occurs. The challenges and future prospects for estimating the gasification reaction area by AE technique are also addressed at the end of article.</p>

  • Deterioration evolution mechanism and damage constitutive model improvement of sandstone-coal composite samples under the effect of repeated immersion

    Underground reservoirs in coal mines, consisting of goafs (By goaf, we mean the space that remains underground after the extraction of valuable minerals), are commonly utilized for mine water storage and drainage, with their primary load-bearing structures being the “roof-coal pillar” systems. Consequently, this structure must endure the repeated immersion behavior resulting from fluctuations in the mine water level, resulting in the risk of geological disasters. This paper analyzes the variation in mechanical properties of sandstone-coal composite samples after repeated immersion cycles through axial loading tests. The results indicate that the water content of the sample exhibits a notable and rapid increase with each successive immersion cycle. This corresponds to a decrease in the stress threshold and modulus parameters of the samples. Moreover, the acoustic emission signals serve as indicators of the softening characteristics of the samples. With the increase in immersion cycles, there is an augmentation in both the frequency and extent of shear cracks. The non-linear failure characteristics of the samples become more pronounced. Consequently, water significantly weakens the cementing material between rock grains. Both sandstone and coal display a decrease in deformation resistance capabilities at a macroscopic level. The constitutive model of the composite sample was improved based on the degradation characteristics of mechanical strength and strain energy parameters, which offers enhanced accuracy in analyzing the degradation process caused by water immersion. This paper offers a crucial theoretical foundation for comprehending the deterioration evolution characteristics of the “roof-coal pillar” bearing structure affected by repeated immersion.

    This paper presents an alternative methodology for the study of flyrock hazards in mining, utilizing Artificial Intelligence (AI) through machine learning by classification. By using distance as a delineator to denote the consequences of a blast, the models generated two classes of blasts: safe and unsafe. In this study, statistical learning models best suited for classification, that is, K Nearest Neighbors (KNN), Support Vector Machine (SVM), Decision Tree (DT), and Artificial Neural Networks (ANNs), were used, and their classification abilities were assessed. Machine performance was evaluated using a Confusion Matrix (sensitivity and specificity) and Receiver Operating Characteristic (ROC) curve. A higher weight was assigned to the minority class (unsafe blasts). Overfitting assessment was also performed. The Wide Neural Network (WNN) demonstrated the highest classification superiority. During training and validation, 75% sensitivity, 100% specificity, and an ROC of 0.9853 were achieved. In the test phase, perfect stratification (100 %) was maintained, with an ROC of 1. The Cubic SVM exhibited 50% sensitivity, 100% specificity, and an ROC of 0.9412 during training and validation. In the test set, it achieved 100% sensitivity, 100% specificity, and a ROC of 1. Fine KNN showed 50% sensitivity, 94.1% specificity, and an ROC of 0.7206 in the validation set. The test set displayed 100% sensitivity, 100% specificity, and an ROC of 1. Conversely, Coarse DT had a higher misclassification rate, resulting in a 25% sensitivity, 76.5% specificity, and an ROC of 0.5221 during the validation phase. In the test set, it showed 50% sensitivity, 100% specificity, and an ROC of 0.75. A feedforward neural network (FNN) was designed, trained, and demonstrated to be a highly flexible classification tool. The FNN achieved an excellent classification score of 100%. These findings demonstrate the potential for the broad applicability of machine learning through classification in addressing flyrock challenges in open-pit mines.

    Box-jacking is an increasingly popular means for installing underground utilities and infrastructure. Accurately estimating the expected jacking forces in box-jacking is a key design concern, which can ensure the available thrust is not exceeded, to prevent damage to the box-culverts and/or launch shaft, and the construction efficacy of the jacking project. However, prediction of the total jacking force is complicated due to a multitude of influencing factors. The development of jacking force can be influenced by the site geology, the lubricant performance, work stoppages, shape of box culvert, and tunnel boring machine driving style. In this paper, a probabilistic observational approach is introduced aimed at prediction of jacking forces during the box-jacking process. Markov Chain Monte Carlo (MCMC) was adopted for this purpose which allows forecasts to be performed within a probabilistic framework. The proposed framework was applied to a box-jacking case histories completed in Kanagawa: a 150-m drive in fine and medium sands. The forecasts were appraised through comparisons to predictions determined using a classical optimization technique, namely genetic algorithms. The results show that the proposed framework yields highly accurate predictions for the monitored field data, and the prediction accuracy improves obviously as more data are acquired from the drive.

    In this paper, a multi-point geostatistical (MPS) method based on variational function partition simulation is proposed to solve the key problem of MPS 3D modeling using 2D training images. The new method uses the FILTERSIM algorithm framework, and the variational function is used to construct simulation partitions and training image sequences, and only a small number of training images close to the unknown nodes are used in the partition simulation to participate in the MPS simulation. To enhance the reliability, a new covariance filter is also designed to capture the diverse features of the training patterns and allow the filter to downsize the training patterns from any direction; in addition, an information entropy method is used to reconstruct the whole 3D space by selecting the global optimal solution from several locally similar training patterns. The stability and applicability of the new method in complex geological modeling are demonstrated by analyzing the parameter sensitivity and algorithm performance. A geological model of a uranium deposit is simulated to test the pumping of five reserved drill holes, and the results show that the accuracy of the simulation results of the new method is improved by 11.36% compared with the traditional MPS method.

    In this paper, a multi-point geostatistical (MPS) method based on variational function partition simulation is proposed to solve the key problem of MPS 3D modeling using 2D training images. The new method uses the FILTERSIM algorithm framework, and the variational function is used to construct simulation partitions and training image sequences, and only a small number of training images close to the unknown nodes are used in the partition simulation to participate in the MPS simulation. To enhance the reliability, a new covariance filter is also designed to capture the diverse features of the training patterns and allow the filter to downsize the training patterns from any direction; in addition, an information entropy method is used to reconstruct the whole 3D space by selecting the global optimal solution from several locally similar training patterns. The stability and applicability of the new method in complex geological modeling are demonstrated by analyzing the parameter sensitivity and algorithm performance. A geological model of a uranium deposit is simulated to test the pumping of five reserved drill holes, and the results show that the accuracy of the simulation results of the new method is improved by 11.36% compared with the traditional MPS method.

    Underground coal gasification (UCG) is the process of directly recovering energy as combustible gases such as hydrogen and carbon monoxide by combusting unmined coal resources in situ. The UCG process is an invisible phenomenon, in which fracturing activity at high temperature (>1000 °C) in coal seams expands the gasification zone and increases the combustible components of the product gas. However, excessive expansion of the gasification zone may cause environmental problems such as gas leakage, deformation of the surrounding ground, and groundwater pollution. Therefore, visualization of the gasification zone of UCG is required for both improving gasification efficiency and developing UCG systems with low environmental impact. In this study, the large-scale model UCG experiments conducted on a laboratory scale (size: 625 mm × 650 mm × 2792 mm (H × W × L)) were carried out to discuss the visualization of the gasification reaction zone of coal in UCG by Acoustic Emission (AE) technique with uniaxial and triaxial acceleration transducers. As the results of temperature monitoring and AE source location analysis show, AE sources are located near the high-temperature zone (>1000 °C). In addition, the located AE sources move and expand with the movement and expansion of the high-temperature zone. AE measurement can be a useful technique for monitoring the progress of the UCG reaction zone. AE measurement with triaxial sensors is also useful to predict a high-temperature zone though the measurable range, which has to be considered.

    To study the principle of balanced mining and the overlying strata movement law in the shallow and thin coal seam using the N00 mining method, based on theoretical analysis, similarity experiments, and on-site measurements in Xintai coal mine, the characteristics of balanced mining and roof movement law between the N00 mining method and traditional mining method were compared and analyzed. The balanced mining characteristics of the N00 mining method were analyzed from four aspects: the movement characteristics of the strata, the damage coefficient of the strata, the subsidence displacement of the strata, and the development of the strata's cracks. The fracture characteristics analysis of the strata showed that the three zones of the overlying strata in traditional mining method are “collapsed zone (I)”, “fractured zone (II)”, and “curved zone (III)”, while the three zones of the overlying strata in the N00 mining method are “collapsed zone (I)”, “curved zone (II)”, and “protected zone (III)”. Through the analysis of the damage coefficient of the strata, it was found that the N00 mining method uses the bulking characteristics of the strata to increase the damage coefficient of zone I, decrease the damage coefficient of the other two zones, and reduce surface damage. Through the analysis of the roof subsidence displacement, it was found that the N00 mining method reduces the subsidence of zone I, II and III by using the bulking characteristics of the strata, and the model surface has basically no subsidence displacement, while the traditional mining method still has subsidence displacement at the top of the model. Through the analysis of the cracks development of the strata, it was found that compared with the traditional mining method, the N00 mining method has more developed cracks in zone I and more complex cracks, and the number of cracks in the other two zones is less than that of the traditional mining method. Finally, through on-site measurements, it was discovered that traditional mining method are prone to significant surface subsidence displacement, whereas the N00 mining method mitigates this phenomenon by means of cutting-strata, expanding the range of zone I, making the strata fully bulked, increasing the damage coefficient of zone I, increasing the number of cracks in zone I, reducing the damage coefficient of the strata near the surface, curtailing the subsidence displacement in surface-proximal strata, reducing the incidence of cracks in the strata close to the surface, safeguarding the surface strata, and ultimately achieving balanced mining.

    Box-jacking as a tunnelling method has gained popularity in recent years for locating underground utilities and infrastructure. Nevertheless, the employment of this technique still poses challenges, particularly in predicting the jacking force of long drives. Accurate prediction of jacking force is highly desirable for anomaly detection, avoiding thrust overload limits, and protecting the box culverts and launch shafts from damage. However, such a prediction entails accounting for numerous factors, including site geology, lubricated overcut, work stoppages, deviations in alignment, and the driving style of the tunnel boring machine. In this paper, technical details of a Japan box-jacking project totalling over 220 m in length are discussed, with a focus on elucidating the relationship between tunnelling parameters and jacking force. Then, calculating approaches for forecasting jacking force during curved box-jacking are introduced. The modified Box-soil-lubricant contact model based on the analysis of tunnelling parameters is adopted for this purpose which can improve the accuracy of forecasts. Forecasts determined by the proposed approach are appraised through comparisons to predictions obtained using the PBK method currently utilized in industry. The results show that the proposed approach provides better forecasts of the monitored field data and highlight the significance of interpreting field data as a valuable tool for assimilating the experience with box-jacking in various ground conditions.

    This study investigates the transition from surface to underground mining at the Sepon Gold mine. The stability of surface slopes is assessed prior to commencing underground operations. Stope mining is adopted based on ore body characteristics and geological features. Finite element numerical analysis, employing the Generalized Hoek–Brown criterion, evaluates slope stability for surface slopes and opening stopes. The pit design comprises a 70° slope angle, 20 m height, and 10–15 m safety berm, meeting stability requirements with a factor of safety of 2.46. Underground mining design includes a 62° ore body dip, a 50 m thick crown pillar to prevent surface subsidence, and 5 m wide, 5 m high stopes. Sill pillars are left for support after each level of excavation. Rock bolts are employed in specific stope areas where necessary, with continuous monitoring for surface deformation. This study analyzes the influence of stope sizes on the pit wall and pit bottom stability, identifying slope failures near the hanging wall close to the pit bottom during underground mining. A slight increase in the displacement zone is observed on the upper crest of the top footwall. Overall, the findings demonstrate successful stability in the transition from surface to underground mining at the Sepon Gold mine.

    Pipe-jacking is one of the trenchless methods being widely used for the construction and maintenance of urban underground pipelines. As an eco-friendly construction method, it has the capacity for the installation of pipelines with diameters from 100 mm (4 in.) to 5000 mm (200 in.) covering the majority needs of municipal pipeline construction and is considered the most widely used trenchless method in Japan. However, there is little English literature that systematically introduces the research and application status of pipe jacking technology in Japan, resulting in a serious underestimation of Japanese research achievements in this field. This paper briefly reviews the origin, evolutionary stages, and classification system of the pipe jacking method in Japan, and representative technological advances are also introduced through case statistics. Meanwhile, the deficiencies in the current classification system of the International Society of Trenchless Technology (ISTT) are discussed as well. In addition, the application status of this method is investigated based on survey data from the Japan Society for Trenchless Technology (JSTT). According to the survey data from 5232 projects, a systematic analysis is carried out on the selection of pipe jacking equipment, the scale of jacking construction, the profile of curved projects, and the geological adaptability of the pipe jacking method in Japan. The emphasis of this paper is to introduce the current technical situation and analyze the development trends of the pipe-jacking method based on Japan's experience, and to popularize this method in other countries that need this simple, effective, and economical construction technique under the background of climate change.

    Underground Coal Gasification (UCG) requires monitoring of the gasification area because the gasification process is invisible and the reaction temperature exceeds 1000 °C. Many fracturing events that occurred due to coal heating can be captured with Acoustic Emission (AE) monitoring technique during UCG. However, the temperature conditions to generate fracturing events during UCG have not yet been clarified. Therefore, the coal heating experiment and small-scale UCG experiment are conducted by measuring the temperature and AE activities in this research to examine the applicability of the AE technique instead of temperature measurement as a monitoring method during UCG. As a result, many fracturing events are generated when the temperature of coal is changed drastically, especially during coal gasification. Besides, AE events increase in the sensor near the heat source and AE sources are expanded widely with the expansion of the high-temperature region. AE monitoring is an effective technique for the estimation of the gasification area during UCG instead of temperature monitoring.

    The accurate forecasting of metal prices is of great importance to industrial producers as the supply of metal raw materials is a very important part of industrial production. The futures market is subject to many factors, and metal prices are highly volatile. In the past, most of the relevant research has focused only on deterministic point forecasting, with less research performed on interval uncertainty forecasting. Therefore, this paper proposes a novel forecasting model that combines point forecasting and interval forecasting. First, a novel hybrid price point forecasting model was established using Variational Modal Decomposition (VMD) and a Long Short-Term Memory Neural Network (LSTM) based on Sparrow Search Algorithm (SSA) optimization. Then, five distribution functions based on the optimization algorithm were used to fit the time series data patterns and analyze the metal price characteristics, Finally, based on the optimal distribution function and point forecasting results, the forecasting range and confidence level were set to determine the interval forecasting model. The interval forecasting model was validated by inputting the price data of copper and aluminum into the model and obtaining the interval forecasting results. The validation results show that the proposed hybrid forecasting model not only outperforms other comparative models in terms of forecasting accuracy, but also has a better performance in forecasting sharp fluctuations and data peaks, which can provide a more valuable reference for producers and investors.

    The increasing demand for tin-tungsten (W-Sn) due to its versatile applications in various industries and its attractive high market price has created a motivation for mining companies to extract deep-seated tin-tungsten deposits in Myanmar at a fast pace to meet the world demands. At Hermyingyi (W-Sn) Deposit Mine, the feasibility of exploiting ore in multiple inclined veins simultaneously is being explored as a pilot project aimed at increasing W-Sn production. Thus, this study is aimed at the development of optimal design and guidelines for excavating multiple veins with stability certitude in weak rock mass based on the evaluations undertaken. The analyses were carried out using FLAC3Dver. 5.0 and Phase2 V 7.0 software. The results demonstrate that excavation of large stope dimensions with ≥ 5 m width in parallel multiple veins simultaneously is not recommendable as the stopes experience high potential stope failure, thus the development of stopes with width dimensions of ≤ 3 m in all the parallel multiple veins simultaneously in weak rock mass conditions is ideal. In terms of space intervals between parallel inclined veins, it is recommendable to undertake multiple vein excavations for gentle inclined veins in weak rock mass conditions only if the interval of the veins is emplaced at ≥ 14 and 10 m for steep dipping inclined veins with good rock mass conditions. The study also shows that the cut and fill method is a more favorable mining method for multiple veins excavation than the open stoping method.

    This paper described the use of fly ash for soil amelioration of acidic soils to promote plant growth. In mining sites, acid sulfate soils/rocks, which contain sulfide minerals (e.g. pyrite FeS_2), have appeared as a result of overburden excavation. The excessively acidic condition inhibits plant growth due to the dissolution of harmful elements, such as Al, Fe, and Mn. Fly ash, an alkaline byproduct of coal combustion generated in thermal power plants is expected to be adopted to ameliorate acidic soils. However, the mixing ratio of fly ash must be considered because excessive addition of fly ash can have a negative impact on plant growth due to its physical/chemical properties. The pot trials using Acacia mangium demonstrate the evolution of plant growth with a 5%–10% addition of fly ash into acidic soil. When the acidic soil has a high potential for metal dissolution, the metal ions leached from the acidic soil are large, making it difficult to improve plant growth due to osmotic and ionic stress. This work suggests that the effects of fly ash on metal ions leached from the soil have to be considered for the amelioration of acidic soil.

    In Indonesia, the adoption of the underground coal mining method is discussed to extend coal production. However, the geological conditions in Indonesia are very weak. In particular, the mechanical properties of the immediate roof/floor in shallow depths are weaker than those of coal. Therefore, the control measures to maintain stability around the developing area should be discussed for safe longwall mining operations. This study discusses the design of safety pillar width in longwall mining under weak geological conditions by using FLAC3D. The study reveals that the conventional equations for the determination of the pillar width, i.e., Obert-Duvall, Holland-Gaddy, and Bieniawski equations, can be adopted to maintain the stability of the pillar itself but are not suitable for the stability of the longwall face because of the influence of the extracted neighboring panels. Additionally, the increase of the pillar width can significantly reduce the fracture zone around the longwall face. Also, increasing the setting load of the powered support can slightly improve the stability. In the pillar design, both the pillar strength and the stability of the longwall face under weak geological conditions need to be considered.

    Carbonatites are generally competent rock masses with Rock Mass Rating class II rating 60–74. In spite of their competency, they tend to be affected by weak features like Mn-Fe veins and/or in situ rock damage due to brecciation associated with carbonatite complexes. Rock slope failure in such hard rocks is complex since such structures within the rock mass form weak links that could potentially control slope instability. In this contribution, a numerical simulation using phase2 v 7.0 was carried out to investigate the influence of in situ rock damage on the stability of mine pit walls. The outcome reveals that the existence of breccia in the competent rock mass has the capability to reduce the slope stability performance particularly at gentle dipping angle of emplacement in close range to the slope toe. However, as the emplacement position of breccia moves away from the pit wall, the stability performance increases at gentle dipping angle < 50º. On the contrary, at the dipping angle of 50°, the performance of slope reduced, and at steeper angle > 50°, the impact becomes negligible. Thus, from a series of analyses, mine design in brecciated rock masses, the ratio of 1:5 between the breccia distance from slope toe and pit depth should be implemented to counter its impact. If the breccia is within or close to the pit limit, a deliberate effort must be made to mine out or truncate it.

    In Indonesia, the adoption of the underground coal mining method is discussed to extend coal production. However, the geological conditions in Indonesia are very weak. In particular, the mechanical properties of the immediate roof/floor in shallow depths are weaker than those of coal. Therefore, the control measures to maintain stability around the developing area should be discussed for safe longwall mining operations. This study discusses the design of safety pillar width in longwall mining under weak geological conditions by using FLAC3D. The study reveals that the conventional equations for the determination of the pillar width, i.e., Obert-Duvall, Holland-Gaddy, and Bieniawski equations, can be adopted to maintain the stability of the pillar itself but are not suitable for the stability of the longwall face because of the influence of the extracted neighboring panels. Additionally, the increase of the pillar width can significantly reduce the fracture zone around the longwall face. Also, increasing the setting load of the powered support can slightly improve the stability. In the pillar design, both the pillar strength and the stability of the longwall face under weak geological conditions need to be considered.

    Vipingo quarry in Kilifi county, Kenya, is one of the quarries supplying coral limestone for limestone manufacturing in the coastal region. Due to its close proximity to the Indian ocean, the semidiurnal ocean tides tend to have an influence on the stability of the quarry slopes adjacent to the shoreline. Finite element numerical analysis using the generalized Hoek–Brown criterion is conducted to assess the stability condition of the slopes followed by slope-angle optimization to determine the safest overall slope angle as well as analyzing the stability of the slopes due to action of varying ocean tides. The optimum overall slope angles for various excavation depths are found to be 52° for 20 m, 46° for 30 m, 42° for 40 m, and 39° for 50 m, which are the same even with varying distance of the slope face from the shoreline. A parametric analysis shows that there is no significant effect of the tides on slope stability for excavations above the water table, but as the quarry gets deeper, the slope stability is affected. A sensitivity factor (ζ) is introduced, being a measure of how much the slope safety factor is reduced as a result of the semidiurnal tidal action.

    This paper attempts to predict the surface subsidence induced by multi-seam longwall mining in the PT Gerbang Daya Mandiri (GDM) underground coal mine in Indonesia. Several numerical models of multi-seam longwall mining under various depths were built in the finite difference code software “FLAC3D” which was used as a tool for numerical simulations. Effect of mining sequence and influence of lower seam mining were firstly investigated. The angle of draw (AoD) and maximum surface subsidence (S_<max>) were used to describe characteristics of the surface subsidence. Based on simulated results, it is indicated that the undermining provides a better mining sequence in multi-seam longwall mining compared to the overmining. Mining the coal seam in an undermining order will not cause any difficult mining conditions in a lower seam, whereas some ground control problems in an upper seam are expected when the coal seam is mined in an overmining order. Under all mining depths in the undermining, extracting the lower seam panels significantly influences the magnitude of surface subsidence. The AoD and S_<max> increase significantly after all panels in the lower seam is mined. This indicates that very large surface subsidence is expected when multi-seam mining is applied at GDM underground coal mine. An application of some countermeasures such as adopting a large pillar width and a small panel width is suggested in this underground coal mine in order to minimize the surface subsidence caused by multi-seam longwall mining. Minimizing the surface subsidence by adopting a large pillar width and a small panel width is therefore numerically investigated in this paper. Based on simulated results, it is found that the AoD and S_<max> decrease significantly when larger pillar width and narrower panel width are adopted. The use of larger pillar width and narrower panel width result in smaller AoD and S_<max>.

    In rectangular pipe-jacking, excessive friction force resulting from the pipe-soil interaction is the dominant factor hindering its further application in long-distance, larger-section, and deep-buried scenarios in urban underground construction. These complex scenes are the frontiers and key issues that need to be developed in this method. To this effect, this paper aims to investigate the pipe-soil interaction and improve the prediction accuracy of the friction force in rectangular pipe-jacking. The widely used friction force solutions were examined based on the actual monitoring data via two field cases in Japan. The reasons for the current overestimation of the friction resistance in rectangular pipe jacking were discussed. To avoid the prediction deviation in the empirical and theoretical formulas, a new pipe-soil contact model for rectangular pipe-jacking was proposed for friction force prediction under the lubricant applied condition. Further, a numerical simulation was conducted using the finite element method to verify the proposed model. Combining the numerical results and field data, the developed model was preliminarily proved and it could provide the prediction accuracy of friction force within 5.5% in the greater Tokyo area. The results suggest that the improved friction force prediction could provide a reference for future designs of long-distance rectangular pipe-jacking.

    Crown pillars provide regional and local support by isolating the ground surface from underground mine workings. Topography above the underground mine may be a relatively flat ground surface or an open-pit structure. Depending on what lies above and design of the underground mine, the crown pillar behaviour will differ. In transitioning setups (open pit to underground), large open pit collapses have taken place as a result of crown pillars located at the transition zone. Hence, this paper focuses on crown pillars between open pit and underground to better understand their behaviour. Taking the Zuuntsagaan Fluorite mine as an example where open pit will transform to underground mining, a remnant ore is to be left as a crown pillar to separate the two mining sections. Through numerical simulation in FLAC3D 7.0, stress distribution and failure mechanisms acting around the crown pillar were monitored as underground mining progresses. Effect of crown pillar geometrical parameters was evaluated, thus crown pillar thickness, span and dip. Further, the open pit geometry influence was also considered on the overall behaviour of the crown pillar. It was found out that in transition from open pit(OP) to underground(UG), slope and stope walls closing in on the crown pillar induce stresses that act as loading from the pillar sides, which in turn influence the failure process.

    Numerical simulation is very useful for understanding the hydraulic fracture (HF) re-orientation mechanism from artificial weaknesses. In this paper, the UDEC T-W (Trigon–Weibull distribution) modeling method is adopted to simulate the hydraulic fracturing process in heterogeneous rocks. First, the reliability of this method is validated against previous laboratory experiments and numerical simulations. Then the effects of fluid rate, fluid viscosity, perforation angle and natural fracture (NF) on the HF re-orientation process in heterogeneous rocks are studied independently. The results show that the HF re-orientation process depends on the combined effect of these factors. The HF re-orientation distance increases significantly, the final HF re-orientation trajectory becomes more complex and the guiding effect of perforation on the HF propagation path is more evident with the increase of fluid rate, fluid viscosity, and perforation angle if the hydraulic fracturing is performed in relatively heterogeneous rocks, while the differential stress is the main influencing factor and is more likely to dictate the HF propagation path if the rocks become relatively homogeneous. However, increasing the fluid viscosity and fluid rate can attenuate the impact of differential stress and can promote HF propagation along the perforation direction. Besides, NFs are also the important factor affecting HF re-orientation and induce secondary HF re-orientation in some cases in heterogeneous rocks.

    The typical reinforcements and supports used in the main gate of underground coal mining (particularly in the weak to very weak rock strata), such as rock/cable bolts, steel sets, and grouting materials, often allow the mine to remain serviceable in the long run, but in complicated geotechnical and geological conditions, they are insufficient. Low rock strength leads to instability and exhibits serious ground control issues. The pipe-jacking method with a precast concrete pipe support can be one of the more appropriate options for significantly improving geotechnical concerns. This paper aims to study the applicability of pipe-jacking technology in underground coal mining based on a series of numerical analyses employing a three-dimensional FEM (3D-σ software, Geoscience Research Laboratory Co Ltd, Kanagawa, Japan). In the numerical analyses, we study the crown deformation and failure proximity using different inclination angles for the tunnel, different highwall slopes, and two different shapes for the pipe. It is important to note that a precast concrete pipe is effective as a primary support system and can improve the stability of the main gate efficiently.

    Developing longwall mining under weak geological conditions imposes a substantial challenge with regard to the higher risk of falling roofs. Maintaining the stability of the longwall face in this aforementioned condition is crucial for smooth operation. Investigating roof conditions in longwall requires detailed study of rock behavior in response to a few key influences. This paper presents the outcome of a numerical analysis of roof stability in shallow depth longwall face under weak geological conditions. A series of validated FLAC3D models was developed to examine the roof condition of the longwall face under the influence of shield canopy ratio, shield resistance force, and stress ratio. The results show that these three key factors have a significant impact on longwall roof conditions, which can be used to optimize its stability. Two distinct mechanisms of the roof caving behavior can be observed under the influence of stress ratio. The countermeasures of reducing face-to-tip distance and cutting width are proposed to improve the roof condition of longwall face under weak rock. The outcomes show a substantial improvement in roof conditions after adopting the proposed method.

    Abstract: For this study, as part of the underground operations, the underground mining sequence was explored for suitability in the Zuuntsagaan mine. Two mining sequences are considered; bottom-up (B-U) and top-bottom (T-B), and the instability of stopes and open pit slopes is evaluated in response to each sequence. For the present rock mass conditions and stress state, with reference to the underground section, the results revealed that T-B sequence has lower ground movements. On the open pit section, the effect of the two sequences is relatively the same while the difference is mainly observed in the underground section.

    For rectangular pipe-jacking construction, the primary priorities of smooth construction include minimizing the ground response and designating the appropriate jacking force to achieve the best results in environmental protection and energy conservation. The geometric cross-section design of the jacking rectangular pipe and its engineering performances such as the ground surface displacement, the jacking force consumption, and the stress-bearing state are easy to be ignored in the field construction. In this paper, the ground response characteristics under four kinds of rectangular pipe aspect ratio (H/W) with the same utilization cross-section area were investigated by using the calibrated finite element method (FEM) based on a case study conducted in Japan. The theoretical jacking force of each pipe section design was calculated and compared to provide a reference for long-distance or large-section jacking conditions. The stress-bearing state of each pipe was considered under different buried depths. The results show that the ground surface response decreases while the jacking force increases with increasing the aspect ratios. Thus, a reasonable design of the rectangular pipe section should comprehensively consider the influence of geometric effects on the ground and its stress-bearing state during the jacking construction. The findings of this study provide a practical reference for the safe and economic design of the jacking rectangular pipe and engineering management.

    Predictive model and formula of jacking force has been well-established for circular pipe jacking in the past decades. However, the frictional mechanism of pipe–soil–slurry and jacking force prediction of rectangular pipe jacking has not well been understood. Nowadays, the rectangular pipe jacking is widely used, because of its over 20% larger effective usable area than that of circular pipe as underground facilities, with the same cross-sectional area. Nevertheless, the corresponding prediction models of thrust of rectangular pipe jacking are lacking. In order to further understand the frictional mechanism of slurry rectangular pipe jacking, five classical analytical calculation models have been proposed, considering the pipe–soil–slurry interaction, and prediction formulas are obtained. Then, 3D finite difference method was introduced to estimate the jacking force by using FLAC3D. Finally, three case studies have been carried out to validate the proposed models. The results show that the numerical and theoretical results have good consistency, and what is more, the measured jacking force can be well included within the ranges of analytical models presented in this paper, which can improve the thrust prediction of rectangular pipe jacking.

    The demand for specific earth retaining wall methods is increasing along with the advancement and overcrowding of underground space use such as the presence of adjacent structures in an urban area. To cope with this, the method named earth stepped-twin retaining wall is increasingly being applied. However, there is a concern about the workplace if the earth pressure causes a heaving and pressing phenomenon from both ends of the retaining wall in the earth stepped-twin retaining wall. Therefore, we proposed the application of an anchor method that contains the inner and outer walls by using numerical simulation. The effects of the difference in soil properties, the horizontal distance between the outer and inner walls, and the depth of the outer wall embedment on the anchor were investigated. The results of this study show that the wall deflection of the inner wall could improve by adopting the anchor support. Besides, it was found that the inner wall can be efficiently suppressed by adopting the hybrid system with anchors and struts according to the soil properties, horizontal distance, and the depth of the outer wall.

    Rehabilitation is an important stage in mining operations for environmental conservation. However, the shortage of topsoil makes it difficult to achieve rehabilitation in open-cast coal mines. Securing topsoil by mixing soil with fly ash (FA), which is treated as an industrial waste, is expected to solve this issue in coal mines. While mixing soil with FA makes it possible to secure the topsoil and treat industrial waste simultaneously, the high alkalinity of FA and the dissolution of heavy metals from FA may inhibit plant growth. This study investigated the effects of FA in the topsoil on plant growth via vegetation tests with simulated topsoil mixed with FA using Acacia mangium, a species of flowering tree: the FA mixing ratios were set to 0%, 20%, 40%, 60%, and 100%. The growth of Acacia mangium was inhibited with increasing FA mixing ratio, especially from 60% to 80%. However, the growth rate of Acacia mangium in an FA mixing ratio of 100% was nearly comparable to that in a mixing ratio of 40%. Furthermore, there were no effects of the physical characteristics and pH conditions in the topsoil on the plant growth at any of the mixing ratios; meanwhile, the accumulated concentration of Al in the plant body increased significantly at an FA mixing ratio of 60%–80%. This suggests that the accumulation of Al, which inhibits plant growth, including root growth and its functions, in the plant body inhibited the growth of Acacia mangium. Therefore, the most important aspect in terms of rehabilitation concerning the use of FA for securing topsoil is not the mixing ratio of FA but the amount of Al in the FA and the accumulation of Al in the plant body.

    Soil erosion is one of the major environmental problems in open-cut mines in tropical regions. It causes negative impacts including the removal of nutrient-rich topsoil, destroys aquatic habitat, dam and pond siltation, clogs river by deposition of sediment, and causes water pollution in the rehabilitation process. Soil texture is an important factor to affect soil erosion. In this study, artificial rainfall experiment in the laboratory scale was conducted to clarify the mechanism of soil erosion under the different soil composition and to discuss the methods for minimizing soil erosion. The obtained results showed that the soil seal generated due to the presence of fine particle under high rainfall intensity is the main contributor to accelerate the soil erosion. Additionally, the surface coverage by the cover crops is the most effective measure to reduce soil erosion because both the coarse and fine contents runoff can be minimized while arranging of the slope angle is effective for reducing the runoff of coarse contents and the soil compaction is effective to reduce that of fine contents. Soil erosion can be minimized by selecting prevention method considering the type of soil because the prevention effect on soil erosion is different depending on the type of soil.

    Characterization of mine waste rocks and prediction of acid mine drainage (AMD) play an important role in preventing AMD. Although high-tech analytical methods have been highlighted for mineral characterization and quantification, simple testing methods are still practical ways to perform in a field laboratory in mines. Thus, this study applied some simple testing methods to the characterization of mine wastes and AMD prediction in addition to a leaching test and the sequential extraction test with HCl, HF, and HNO3, which have not been applied for these purposes, focusing on the form of sulfur and the neutralization effects of carbonates. The results of the Acid Buffering Characteristic Curve test supported the changing trend of the pH attributing carbonates only during the first 10 leaching cycles in the leaching test. The change in the Net Acid Generating (NAG) pH in the sequential NAG test reflected the solubility of sulfur in the rocks, providing information on the form of sulfur in the rocks and the acid-producing potential over time. Consequently, the sequential NAG test and sequential extraction with the acids in combination with the current standards tests (Acid Base Accounting and NAG tests) provided important information for preventing AMD.

    Most of coal is produced from open-cut mines in Southeast Asian countries. However, the conditions of their surface mines are worsening each year: the stripping ratio is increasing, approaching economic ratio and the regulation of environmental protection. To meet the demand for coal, underground mines have to be developed in the near future. Under these circumstances, the development of new coal mines from open-cut highwalls are being planned in Southeast Asian countries. Moreover, some of the Southeast Asian mines have thick coal seams. However, if the conventional mining systems and designs introduced in US, Australia and European countries are applied, several geotechnical issues can be expected due to the mines’ weak geological conditions. From these backgrounds, this paper proposed a punch multi-slice mining system with stowing for thick coal seam under weak geoligical conditions and discussed its applicability and suitable design by means of numerical analysis.

    Acid Mine Drainage (AMD) problem is considered as one of the serious problems in mining operation in the world. This problem is generated due to sulfide minerals in waste rocks. Sulfide minerals are very commonly included in any types of crustal rocks, resulting in AMD and a negative impact on the ecosystem. In this research, some experiments were conducted with the rocks sampled in the open pit coal mine in Indonesia to understand the effects of the rock condition on acidic water generation. The result indicated that wetting and drying process affected the disintegration of rocks caused by both physical and chemical factors in the rock sample. Hence, AMD generation is promoted due to both factors while waste rocks are stored in tailings in the current system. It suggests that the system for waste rock management should be improved to prevent AMD generation.

    Dumping areas represent a stable hazard. To clarify the formation mechanism of dumping piles on
    dumping area stability, an investigation in open pit mine was performed. Moreover, experiments
    with gravel were conducted based on the research site conditions. The geological conditions,
    dumping operation, and waste particle size distribution were investigated in the Heidaigou open
    pit mine. Particle size distribution, dumping height, dumping volume, and floor inclination were
    varied to examine their effects on a single pile formation. The design of blasting can be modified to
    make the particle size of waste smaller. The volume of the bucket does not have a pronounced effect
    on dumping pile repose angle, capacity of dumping pile, and dumping area stability. The smaller
    the floor inclination, the better it is. Two measures are proposed to increase the kinetic force of
    friction between waste material and floor surface. The interval distance, dumping volume and
    dumping height were also varied to examine the interaction between the formations of multiple piles. The dumping width should be decided through optimization efficiency of bulldozer and dumping device in bucket wheel excavator-belt-stacker dumping operation and dragline dumping operation. Moreover, the volume of the bucket does not have a pronounced interaction effect. In the dumping operation, the work amount of bulldozer decreases as dumping pile increases.

    A detailed study to propose new design support systems for underground mine was carried out in this paper. Serious shotcrete failures have often occurred in Cibaliung Underground Gold Mine in Indonesia. Three main rock types, quartz vein as ore body, andesite-breccia altered by clorite-adularia on foot wall abundance and andesite-breccia altered by smectite-illite dominant on hanging wall rock. The cut and fill mining method was selected for this mine in accordance with the geometry of vein, topographic specifications, and annual production rates. Excavation size, distance between stope and decline, depth, and the impact of fault will influence the induced stresses. Different depths in multiple excavations were analyzed in this study especially on decline area. In this study, the engineering properties of rock masses were defined from field and laboratory test for each rock types. Support systems for decline were designed based on the suggestions of the Rock Mass Rating (RMR) system and the Q system of rock mass classification. Induced stress on different levels were calculated to define Stress Reduction Factor (SRF) and applied to predict the support system by Q system.

    Cibaliung Underground Gold Mine applies cut and fill mining method to optimize ore production and maintain under-ground stability. Existing 5 m × 5 m height and width of stope geometry has a potential new design to increase produc-tion of gold due to variety of thick ore, however serious shotcrete failures often occur in hanging wall decline. This pa-per aims to find out the relationship between stope design and stability of hanging wall decline. The analysis conducted in this study is based on underground characteristics and geological condition of Cibaliung area. The impact of stope design on decline stability was analyzed by using numerical methods. The impact factors such as different rock mass, size of stope, and distance between stope and hanging wall decline were used in the analysis of underground stability especially stability on hanging wall decline.

    To improve the accuracy of signal analysis and processing for the underground microseismic waves, an optimal basis function is indispensable in the wavelet packet transform (WPT). Based upon the microseismic wave groups monitored in a deep coal mine, wavelet bases in the Daubechies, Symlets and Coiflets families were screened, and the optimal wavelet packet basis was strictly determined by its reconstruction capability on the original wave and its conservation capability on its characteristic components. Signal reconstruction and conservation capabilities were evaluated by two parameters, root mean square error and correlation coefficient. The energy reserving capability of the optimal basis function was finally discussed to verify its superiority. The results turn out that the wavelet bases db1, sym4, sym5 and sym8 are more appropriate for the microseismic wave compared to others as their better signal reconstruction capability. Among them, basis sym5 is the optimal wavelet basis function for the microseismic wave. When processed by the wavelet basis sym5, the maximum energy components of waves are effectively reserved and the reconstructed characteristic components have the highest relevancy with that of the original wave.

    Indonesia produces over 350Mt of clean coal in 2012 and is the second largest coal exporter to Japan, accounting for 30 Mt/y. Almost of the coal produced is from open cut mines. Mining operation of open cut mines gives serious impacts on surrounding environment. Therefore, an appropriate rehabilitation program has to be taken into consideration when the mine plan is designed.
    Indonesia belongs to tropical rainforest climate and the average annual rainfall shows 2,000~4,000mm/year. One of major environmental problem occurred in rehabilitation area is soil erosion due to heavy rainfall. Soil erosion is easy to accelerate under the high rainfall level, especially in sharp cloudbursts such as squall.
    From series of investigation and discussion, the soil spread to rehabilitation area shows different soil composition due to mixing overburden during soil stripping and stockpiling process. Moreover, it can be expected that this condition could be critical factor for the risk of soil erosion. Therefore, adequate rehabilitation process to limit soil erosion has to be considered such as establishment of erosion control structures and rapid growing cover crop species.
    This paper describes the current situations in rehabilitation area at one of open cut coal mine in Indonesia and several considerations on soil erosion.

    Mangkalapi-2 Pit is a pit in Batulicin coal mine site, South Kalimantan, operated by PT Arutmin Indonesia. The mining operation in this pit has come to the last stage and will proceed to the closure stage in the near future. According to the mine closure plan, Mangkalapi-2 will be directed to be recreational lake for the community. Currently, the water quality in the Mangkalapi-2 pond is relatively good with pH above 6.5. However, considering the characteristics of lithology in the area which indicate the capacity to generate acid drainage, hence a study to assess the future condition of pit lake water quality is necessary.
    The study began with rock and water sampling in Mangkalapi pit and its surrounding. Rock samples were employed for the geochemical composition while the water samples were analyzed for some quality parameters. The simulation on post-mining water quality was conducted using the PHREEQC software. The laboratory kinetic test using Free Draining Column Leach Test was also performed for some selected rock samples.
    Simulation was conducted for different scenarios based on the assumed distribution of sulfide minerals in the pit wall. The results of simulation have indicated the potential of acid water with pH value range from 4.48 to 5.10. Scenario of mixing of leachates from different leach columns containing different type of rock samples was also being simulated for comparison.

    Coal production in Mongolia has rapidly increased with the development of new coal mines; from 5 million tons in 2000 to 25 million tons in 2012. However, in accordance with the rapid development of coal mines in Mongolia, geotechnical, operational and environmental issues have occurred such as the stability of highwall/lowwall and dumping/stock piles, the maintenance of transportation system, etc.
    Especially, the geotechnical investigation and data are insufficient in main coal deposits. This is main cause of current problems such as slope slides, failures and collapses occurred at most open pit coal mines. In order to develop an appropriate mine design, these investigations have been conducted. In addition, the geological data has to be collected and urgent issues for further coal mine development were discussed.

    Although the extraction in the stress relaxation zone of deep multi-seam coal mining is relative safely, unnatural accidents still occur occasionally and sometimes threaten worker’s life security seriously. To explore the primary factor that caused these issues, the characteristics of lateral stress reconstruction and floor failure behavior in interlayer rock mass were surveyed based upon a series of field investigations. And both the redistribution of principle stress and phenomenon of interlayer rock failure were analyzed by numerical simulation. Then by the infinitesimal strain method, two types of infinitesimal analysis models in vertical and horizontal direction respectively were created to explore the reason of floor failure behavior and the mechanism of localized stress concentration. And the impact of localized stress concentration in interlayer rock mass induced by the extracted liberated seam on the subsequent extraction of protected seam was discussed finally. Main findings indicate that a certain extent of localized stress concentration in interlayer rock mass induced by the increased lateral stress results in these accidents. Reconstructed lateral stress provides the mechanical conditions for rock element failure; meanwhile the rock failure behavior further aggravates localized stress concentration in its lower half. Based upon the impact of localized stress concentration in interlayer rock mass, an extraction of protected seam is divided into safe, risky and general types, which helps the reliable mining in deep multiple coal seams.

    The number of coal mines with coal and gas outburst is shooting up with mining depth increasing in China. Mining protective coal seam is one of the most effective technologies preventing coal and gas outburst for mining high-gas multi-seams with low permeability. However, the difficulty of controlling roadway stability in upper protected seams above the gob jumps after mining lower protective coal seam. Based on the problem of surrounding rock stability control for roadway in the overlying protected seam of high-gas multi-seams through ascending stress-relief mining in Huainan mining area, the numerical simulation model is established according to actual engineering to analyze the redistribution of stress during roadway excavation and mining lower protective coal seam, and influence of bolt support on fissure and displacement fields of surrounding rock. Support technique of “three-high” bolt support system combined with pre-stressed anchor cable beam structure is put forward that is successfully applied in Guqiao Coal Mine. Field measurement has proved that the deformation of surrounding rock tended to be stable in 41 days after the support scheme was implemented in the roadway that was excavated in the upper protected seam in 150 days after mining the lower protective seam.

    Acid Mine Drainage (AMD) is one of the serious problems which are caused in the mining operation and it may impact on the ecosystem due to low pH. Considering the fact that the dumping site is a large stockpile of waste materials and it is always exposed to the local climatic conditions, this area can be deemed as one of the sources of AMD. Therefore, it is important to prevent the occurrence of AMD from dumping site after constructng it. This paper describes the results of field investigation and laboratory experiment about AMD problem, and discuss the relevancy between the inner structure of dumping site and the occurrence of AMD.

    The present article deals with the finite element (FE) method numerical simulation of longwall
    mine excavation associated with magnitudes and distribution contours of major principal stress
    (σ1), minor principal stress (σ3), absolute verthideical displacement, and strength factor that are
    essential for the backfill study of the Barapukuria coalmine in northwest Bangladesh. Backfill
    refers to any material that is placed into voids mined underground. Consideration of a suitable
    backfill material along mine voids is a common technique in coalmines for the control of ground
    pressure; manage of deformation of surrounding rock strata of a mine panel, and prevention of the
    ground movement and fracturing of overburden strata. Four stages of calculations have been
    considered in the present modeling. The magnitudes and distribution contours of major principal
    stress (σ1) imply that the allowable compressive strength of backfill material for the Barapukuria
    underground coalmine would be ranged between 0.8 MPa to 1.3 MPa. The absolute vertical
    displacement value was ranging from 0.024 m to 0.028 m at the immediate roof before backfilling.
    Strength factor with variable results were obtained in all stages of simulation. After extraction of
    coal, the strength factor at the immediate roof associated with surrounding of the excavation zone
    was ranging from 0.43 to 0.86. However, subsequent to backfilling, strength factor was increased
    to 1.71 within the excavation area, which indicates a reasonable factor of safety to prevent ground
    movement. Finally, it is suggested to think about backfill technology associated with longwall
    mining at the Barapukuria coalmine that would increase production rate and mine safety.

    Mae Moh mine is the largest open-pit lignite mine in Thailand. In this mine, the development of underground mine from final highwall is considered after the surface mining operation is finished. Longwall mining is a common method for extracting coal from various thickness of coal seam. However, due to unfavorable geological conditions such as weak strata and huge final pit slopes, various preliminary studies on the introduction of underground mining systems have been conducted so far. This paper discusses the applicability of longwall mining system and its suitable design by means of three-dimensional numerical modeling: FLAC3D.

    Open cut mining is the typical mining method to produce coal in Indonesia and it gives serious impacts on surrounding environment. Therefore, an appropriate rehabilitation program has to be designed. The basic concept of rehabilitation in open cut mines is the creation of a stable and self-sustaining land surface. Hence, the soil characteristics and adequate selection of species to plant in rehabilitation area have to be considered. This paper describes the current situations in rehabilitation area at one of open cut coal mine in Indonesia and then discusses the effect of soil composition for growth of Paper Mulberry as one of effective species planted in post mine surface based on the laboratory tests.

    The semi-circular bend (SCB) specimen was suggested in 1984 for testing mode I fracture toughness of rock. Recently, SCB specimen was extended and improved for many other applications by various researchers due to ease in handling though short rod (SR) specimen is recommended method. However, there are still rooms to consider for determining the fracture toughness of rock exactly by SCB specimen. This paper discusses the application of the SCB specimen for determining the fracture toughness of rock by comparison between the result of SCB specimen and SR specimen, and size effect using the SCB specimen.

    The EGAT Mae Moh lignite mine is the largest open-pit coal mine in Thailand. The total geological and economical reserves of Mae Moh coal field are approximately 1,140 Mt and 825 Mt, respectively. The annual production is 12 Mton, which represents 90 % of the total coal production in Thailand, and tends to decrease gradually. In this mine, the development of underground mine from final highwall is considered after the open-pit mining operation is finished. Longwall mining is one of the common methods for extracting coal in various thickness of coal seams and is much more effective, productive and safer than any other mining methods. The productivity of longwall mining is potentially high because it is basically a continuous operation requiring fewer workers and allowing a high production rate to be sustained. Due to unfavorable geological and geotechnical conditions such as weak strata and huge final pit slopes in this mine, however, various studies on the introduction of underground mining systems have been conducted so far. Optimizing boundary and/or safety pillars and panel design for both safety and economics is a key part of planning longwall mines. This paper discribes the applicability of the longwall mining system from final highwall and its suitable design taking the slope stability into consideration by means of three-dimensional explicit finite-difference program FLAC3D producted by ITASCA.

    In modern mining industry, the blasting technique is one of the most adopted techniques for rock excavation and fragmentation due to its economical and efficient aspects. However, compared with other methods, the use of explosives in blasting is limited by law as it may have a severe impact on the surrounding environment such as vibration, noise and dust. Especially, a ground vibration induced by blasting has to be paid much attention in the mining operation as it may give an obvious impact on the surrounding facilities and buildings and in many established safe level blasting criteria, the ground vibration level is characterized by using three parameters; duration, amplitude (peak particle velocity :PPV) and frequency. Current studies on the blast-induced ground vibration focus on two parameters amplitude and frequency that suggested by USBM when the concerned subject is structure, i.e.. Hence, the control of PPV and dominant frequency are very important in order to design an appropriate blasting standard and minimize its environmental impacts.
    This paper discusses the propagation behavior of blast-induced ground vibration in the open pit mine and study by means of field experiments and numerical simulation. In addition, the methods for reduction of blast-induced ground vibration are also discussed by means of numerical simulation in this study.

    Acid Mine Drainage (AMD) is one of the serious problems which are caused in the mining operation. The main factors which cause the problem are H2O and O2 and sulfide minerals such as iron pyrite. Sulfide minerals are usually contained in any type of crustal structure, and there is a possibility of generation of AMD in any area. The problem may impact on the ecosystem or people in the surrounding area since the acidic water is low-pH and usually contains high level of heavy metals. Therefore, it is important to prevent the problem in mining operation. A passive treatment is low-cost and easy to maintain for dealing with AMD problems. In a passive remediation, the study on behavior of AMD generation and elution behavior of heavy metals in a laboratory is necessary before introducing it in the mine site to construct it designed for the situation. Moreover, elution behavior may be changed by management of waste rock, as a practical matter, acidic water generates due to a rough treatment of waste rock in some mine sites. Therefore, in this research, the study on the waste rock was conducted for predicting a quality of acidic water by characterizing the rock and for elucidating effects of treatment of waste rock to elution behavior of heavy metals. This paper describes the results of laboratory experiments such as a column test and a sequence extraction for predicting elution behavior of heavy metals and an occurrence of acidic water, and treatment of waste rock for effective countermeasure for dealing with acidic water for a long term is discussed.

    Mining operation of open cut mines gives serious impacts on surrounding environment such as disturbance of the tropical rainforest, the pollution of surface and/or ground water, subsidence and erosion. Under such situations, rehabilitation is one of the important and considerable topics for an environment protection. Adequate rehabilitation program will solve these environmental issues and recover the ecosystem. The basic concept of rehabilitation in open cut mines is the creation of a stable and self-sustaining land surface in post mine surface involved the creation of conditions suitable for the establishment and permanent development of a dense cover of vegetation. In usual, a lot of open cut mine keep the topsoil individually in the natural forest during soil stripping process and spread the topsoil to rehabilitation area for success of revegetation. However, there are some considerable points for dealing with topsoil in situ such as the soil properties and severe compaction by heavy equipment. Therefore, the proper topsoil management has to be considered for establishment of vegetation in post mine surface.
    This paper describes the current situations of rehabilitation at one of open cut coal mine in Indonesia and the results of investigation about the characteristics of soil spread in rehabilitation area as plant base.

    Today's pipe jacking technology in Japan is used as a construction method for pipe lines, such as water, sewer and power supply. This method has been achieved remarkable progress with the development of technical infrastructure. Usually, circular pipes are used for pipe line construction. Recently, various infrastructures are buried underground, and the effective use of underground is demanded. From this situation, demands of the pipe line construction using rectangular pipes are increasing gradually. To cope with these demands, the Box Culvert Pipe Jacking Method using rectangular pipe jacking machine was developed and has been used for rectangular pipe line construction.
    This paper introduces about the characteristics and applicability of the rectangular pipe jacking method and shows the rectangular pipe line construction case using rectangular pipe jacking machine

    In Japan when urban infrastructures need to be constructed, the difficulty of utilizing the ground or shallow strata will necessarily lead to the more frequent use of the deep strata. The common construction methods are open-cut, pipe jacking, and shield methods. In recent years a new pipe jacking method has been established that can be adapted to 20 m below the ground or more. Using the method, the drivage machine and the jacking pipe continue to move an underground until the completion of the driving. Therefore an over-cutting area (so-called tail-void) must be formed to lower the friction between the ground and the pipe. The over-cutting area is filled with lubrications. However, because the stress release of the ground continues to advance when the over-cutting area is formed, there are some challenges required to cope with the stability of the surrounding ground. In order to utilize the pipe jacking method in the deeper strata layers, the theory, analysis and installation of over-cutting area have to be systemized, and such systematic data must be stored. Therefore, the conditions of over-cutting area in the deep pipe jacking method are discussed using numerical analyses. Moreover, a lubricating material comprised of a mixture of surfactant and fly ash was developed for the application of pipe jacking in deep strata.

    The construction of sewerage with non-excavation technology includes both the renewal method and the pipe jacking method. When carrying out works in urban areas in Japan, the pipe jacking method, with which increasing numbers of pipelines are constructed, has been replaced by the conventional open cut method. This is due to difficulties such as conjested underground installation, features of roads making them prone to traffic jams, problems with traffic control, the impact of noise and vibration on nearby houses, and the limited work area which needs to be excavated from the road’s surface when excavating the open cut method. In addition, a large diameter of 3,000 mm or more has been promoted in recent years. On the other hand, many sewage-pipes renewal technologies that have later become superannuated have been developed. The technology for renewing superannuated or damaged tubes consists of two methods; replacing an existing tube with new tube by breaking the existing tube, and lining the inside of an existing tube.
    Our paper will discuss the application of the construction method for infrastructure using pipe jacking in Japan. Moreover, some examples of this method for pipe renewal systems will be shown.

    In the last decade, the price of gold continues to rise, that generate mining activities increase linearly. Indonesia is one of the top ten gold producers in the world. One of the gold mines in Indonesia is Cibaliung Underground Gold Mine where located in west part of Java Island. Follows the trend, increasing production will be further target of this company.
    The type of ore of Cibaliung underground gold mine is vein with low sulphidation. Basaltic andesite, andesite porphyritic, andesite breccia and vein breccia are constituent rocks and altered by smectite and chlorite. The mining method that carried out this mine is relative similar with some underground gold mines in Indonesia (Pongkor and Nusa Halmahera Mining) i.e. cut and fill mining method. For underground mine, geological information is a key to design such as geological structure, rock mass classification, discontinuities, and other geological parameters. They are linked each other. Four types support system has been recommended in Cibaliung mine. However some cracks still occurred in shotcrete support system along decline access. This paper discusses about support design of cut-and-fill mine method at underground gold mine. Commercial software namely Phase2® is used to review the stability of support system. Rock mass classification includes Q system and RMR, and laboratory tests were carried out to determine parameter for numerical modeling analysis.

    Due to large mining depths, sometimes the stripping ratio becomes so large that some coal around the end-wall cannot be mined considering the economic factors at large-scale open pit coal mines in China. Also, to meet requirements of haul roads in the end-wall transporting system, wide transportation benches have to be left, which makes the slope angle of the end-wall slope smaller. Consequently, a large quantity of coal has to be left under the final end-wall slope. For these remaining coal resources, they will be buried again by the inpit dumping site and are impossible to be extracted once more in future. Therefore, how to recover the remaining coal around the end-wall slope with a safe and efficient extraction system before they are buried by the inpit dump is very urgent and valuable research for open pit coal mines in China.

    Lubrication can effectively reduce the needed thrust if a discrete layer of lubricant is maintained between a pipe and the excavated soil. A lower frictional force allows greater jacking lengths to be achieved. The reduction of frictional stress around the pipe strongly affects the efficiency of lubrication injection. The lubricant must be designed to form a layer in the surrounding soil, be pressurized to overcome ground water pressure and stabilize the over-cutting area. The lubricant should also fill the over-cutting area completely to minimize surface settlement. However, for a commercial lubricant to be effective, it has been suggested that ingredients such as sodium and potassium be eliminated. As a result, in order that a lubricant does not lose its function as a support against the overburden pressure of an over-cutting area and to enable a reduction in thrust, a higher quality lubricant which can overcome these problems must be developed as soon as possible. In this paper, in order to examine the characteristics and behaviour of a material developed as a lubricant and backfilling for a deeper strata excavation system such as a pipe jacking, a fundamental investigation is performed and the various results are discussed.

    The EGAT Mae Moh coal mine is an open-cut coal mine in Thailand that produces about 16 million tons of lignite annually to generate 2,400 MW of electricity. The surface mine pit covers is 4 km by 7 km with mining depths ranging up to 260 m. A large pit slope is formed with the progression of the mining operation. However, massive slides in the pit slope occur often due to the existence weak planes such as faults and bedding, and the weak mechanical properties of the rocks. Hence, 200 m to 300 m boundaries of rock block including coal seams are left in front of faults in order to prevent slides and maintain the stability of the pit slope. As a result, there are significant coal reserves beneath the abandoned area along the pit slope. The focus of this paper is on the applicability and design of the highwall mining for recovering much of the coal left along the pit slope.

    This paper describes a fundamental study on deep underground pipe construction using a pipe jacking method. This study is aimed to discuss the probability of failure under constructing pipe in deep underground. The study has been carried out using a numerical simulation method. The 3D-σ was used to analyze the failure proximity. The failure proximity is based on the failure criterion of Mohr-Coulomb. This study was carried out by changing some influential parameters of the condition of the pipe and surrounding ground i.e. overburden, thickness of pipe, friction resistance, and aberration from the center of distributed force in order to grasp a response of the failure proximity. The simulation result shows that the failure proximity of the pipe rises with increasing overburden, friction resistance and aberration from the center of the distributed force, while on the other hand the failure proximity reduces by increasing thickness of the pipe.

    Dumping area consists of the artificial slope which had been piled up by the mining waste granular. Dumping operation is one of the important works in open-pit mines. Overburden is stripped and waste soil/rock is transported to dumping area in order to expose and extract coal seams. Dumping operation is to transport waste rock from mining working face to dumping areas, and then form benches for slope stability and rehabilitation. This work spends much cost and represents a significant investment. Waste embankments usually have little if any practical use and may represent a long-term liability in the form of a potential source of pollution or stability hazard. Because of economic considerations, a risk of slide and a potential of its environmental impacts, dumping sites must be designed carefully.
    However, the systematic researches on the stability of dumping sites are quite few and the large scale landslides still occur in the dumping sites. For instance, on October 29, 1991, a large slide which volume was about 10 Mm3 was occurred in the south external dumping site of Antaibao open pit mine in China. This slide caused 6 fatalities and many facilities loss. At present, a greater effort must be paid for the design and formation of appropriate dumping sites in order to save the investment, maintain the stability of dumping sites, mitigate the environmental impacts, and promote a long-term reclamation.
    Moreover, in dessert area for instance north-west China and Mongolia, the dumping material is “loess” and landslides and subsidence often occur in their dumping sites. One of the major causes is the characteristics of loess. The strength of loess changes dramatically due to its water content and it becomes to be low under wet condition. The systematic researches on the stability of dumping sites of loess are also quite few because the property of loess is very unique.
    This paper describes the present conditions of dumping sites in open pit coal mines and then discusses the formation mechanism of dumping piles under different conditions based on the results of laboratory tests.

    Indonesia produces over 350Mt of clean coal in 2012 and is the second largest coal exporter to Japan, accounting for 30 Mt/y. Almost of the coal produced is from open cut mines. Mining operation of open cut mines gives serious impacts on surrounding environment. Therefore, an appropriate rehabilitation program has to be taken into consideration when the mine plan is designed. The basic concept of rehabilitation in open cut mines is the creation of a stable and self-sustaining land surface in post mine surface involved the creation of conditions suitable for the establishment and permanent development of a dense cover of vegetation. Hence, the soil characteristics in rehabilitation area and adequate selection of species to plant in there have to be considered.
    This paper describes the current situations in rehabilitation area at one of open cut coal mine in Indonesia and then discusses the application of Paper Mulberry as one of effective species planted in post mine surface based on the laboratory tests.

    Tunnel drivage machines, such as the shied machine, are now widely applied for the construction of underground space. In recent years, the distance of their construction span has been increasing and the shield tunneling system can be applied for ground that contains cobble stones and gravel soil. Therefore, the application of a shield drivage machine has become wider due to their advanced technology. However, once the conventional cutter bit hits with cobble stone and/or a boulder stone, the cutter bit fails and the cutting efficiency decreases dramatically or is completely lost. Therefore, the improvement of the impact resistance of their cutter bit is one of the major research topics for a shield tunneling system.
    This paper describes the multi-layer structure bits developed in our research and discusses the impact resistance and suitable design by means of laboratory tests and numerical simulation.

    Natural ground generally consists of various types of soils and each soil independently reacts with cementing materials. In order to realize uniform and stable soil ground improvement, it is preferable that the excavated soils are vertically mixed together as a whole. Chain Conveyor Cutter (CCC) is like a chain conveyor but is installed vertically on a pile driver, sunk into and is raised up from the ground. An 180 kw water cooled electric motor rotates chain units and enables CCC to cut harder soils at the bottom of the machine discharging cement slurry. The soils and cement slurry are hauled up by the scraper bars of the chain units being mixed together on the way up to the ground surface, which consequently establishes stable improved ground.

    This study proposes a method for hazard assessment in mines based on seismic energy distribution.
    To minimize the influence of external factors on conventional methods, a long-term large-scale seismicity observation was carried out in nine underground coal mines in China. A significant amount of data from seismic events were obtained and used as the statistical sample. For ease of analysis, the seismic energy was formatted by uniform criteria. A distribution-free hypothesis test was applied to determine the probable pattern of the seismic sample. The probability distribution of seismic datasets, the energy characteristics of abnormal seismic events and their commonality with rock burst were discussed. Hazardous seismic outliers were identified based upon the statistical rule. Finally, the seismic energy gradient was determined, and the weighted energy eigenvalue was created to balance the hazard assessment. Our main findings show that the randomization of seismic events is restrained. Seismic energy distribution is abnormal and inconsistent with other common distribution types. Both the anomalous critical values used for identifying the seismic outliers and the weighted energy eigenvalue of a continually increasing energy gradient played a positive role in evaluating its hazard level. The new assessment method has been shown in this study to be objective and effective.

    Mine mineral demand in the world is increasing with the increase of mineral price and gold is one of the rapid increase mineral in a last decade. Geological information is a key for underground design. The most important parameters are geological structure, rock mass strength, main stress and strain, rock mass classification, discontinuities, etc. All of these may have impact on underground stability, if some are suitable, and only just one is troubled, it can be due to instability in underground.
    Cibaliung Underground Gold Mine (CUGM) is one of the gold mines in Indonesia were located in west part of Java in Indonesia. The type of ore is vein with low sulphidation epithermal deposit. This underground mine has two-shot targets; Cikoneng area, production is carried out predominantly through the hanging wall, and Cibitung area, production is primarily through the foot wall of the vein. In this paper, are discussed the fundamental information regarding the cracks those occur on shotcrete along Cikoneng Decline as a main road in CUGM. Field investigation such as scan line method, joint orientation measurement combine to secondary data is used for this study.

    The Mae Moh mine is located in Mae Moh district, Lampang province, about 630 kilometers north of Bangkok, Thailand. This mine is operated by EGAT (Electricity Generating Authority of Thailand), and it is the largest open-pit lignite mine in Thailand. The total geological and economical lignite reserves of the Mae Moh coal field are approximately 1,140 million tons and 825 million tons, respectively. The annual production is about 16 million tons, which represents 70 % of the total coal production of Thailand. All of the lignite produced from the mine is supplied to the 2,400 MW Mae Moh power plant, which is providing 15% of the total electricity demand of Thailand. 347 MT of lignite has been produced, and the remaining future reserve is about 478 MT (as of 2010). In the near future, the open pit limit will be reached and underground mine will be developed from the depth of 400-600 m from the surface. However, due to the problems such as poor geological conditions, extra thickness of coal seams (20-30 m thickness) and weak mechanical properties of rock, various studies, such as final open pit stability, an applicable underground mining system for Mae Moh mine are being conducted at the present. In this paper, it is discussed the response of pit slope in different extent of rib pillars, which is measured horizontally minimum distance from the open pit wall to underground mine, and in different size of panels and mining height, and the interaction between open pit slope and underground working by means of numerical analyses using three-dimensional finite difference code FLAC3D.

    Dumping area consists of the artificial slope which had been piled up by the mining waste granular. Dumping operation is one of the important works in open-pit mining operation. Overburden is stripped and waste soil/rock is transported to dumping area to expose and extract coal seams. Dumping operation is to transport waste rock from mining working face to dumping areas, and then forming a bench for slope stability and rehabilitation. This work spends much cost and represents a significant investment. Waste embankments usually have little if any practical use and may represent a long-term liability in the form of a potential source of pollution or stability hazard. Because of economic considerations, a risk of slide and a potential of its environmental impacts, dumping sites must be designed carefully.
    However, the systematic researches on the stability of dumping sites are quite few and the large scale landslides still occur in the dumping sites. For instance, on October 29, 1991, a large slide was occurred in the south external dumping site of Antaibao open pit mine. The sliding volume has about 10Mm3, caused 6 person death and a huge property loss. At present, a greater effort must be paid for design and formation of appropriate dumping sites in order to save investment, maintain dumping sites stability, mitigate environmental effects, and promote long-term reclamation.
    Moreover, the dumping material is “loess” in dessert area for instance north west China and Mongolia where the seismic disasters such as land slide and subsidence occur. The strength of loess is high under dry condition. On the other hand, it becomes to be low under wet condition. The systematic researches on the stability of dumping sites of loess are also quite few because the property of loess is very unique.
    This paper describes the field investigation conducted in Heidaigou open pit mine where overburden material is loess in China and discusses the formation mechanism of dumping piles under different conditions based on the results of laboratory tests.

    Rock blasting is the rock excavation technique most widely adopted in the various fields of the mining and construction industries because of its economical and efficient aspects.
    However, the application of blasting technique is limited by law because it may have a serious impact on surrounding environment such as ground vibration, noise and dust. Especially, ground vibration may cause the damage to the surrounding structures. Thus, mining companies which apply the blasting technique have to control the blast-induced ground vibration in order to minimize or eliminate the possibility of damage to nearby structures or to reduce complaints from neighbors.
    As many researches have studied on blasting techniques and its impact on the surrounding environments, several equations and methods for prediction of blast-induced ground vibration have already been proposed so far. Most of them adopt the Peak Particle Velocity for evaluation the degree of blast vibration. Each particle in the rock mass vibrates in a complicated motion, which is approximately elliptical motion in several cycles with varying amplitudes. The highest velocity during this motion is called as Peak Particle Velocity (PPV). However, the general prediction equation and/or method have not been developed yet because the different rock parameters and ground conditions have an obvious impact on elastic wave propagation.
    From these points of view, the 2-D numerical simulation method has been developed and evaluated by means of the results of field experiments in this study. In addition, a case study has also been conducted by using this numerical simulation in order to discuss the effects of ground conditions on blast vibration in quantity.

    In Japan, the number and the scale of public works and construction of buildings have been decreased due to the recession and the critical public opinion about public works. However, the necessary public works have been done as same as before.
    Development of aggregate resources for use in structural concrete has been encouraged in Japan to support infrastructure improvement and national land conservation. Natural aggregate is a valuable resource necessary for sound economic development and its importance is growing. However, against the backdrop of the ongoing depletion of resources, growing concern over nature conservation and increasingly tightened control over resource use, the supply of natural aggregates such as sea/river/pit sand and sea/river gravel has been decreasing.
    Natural aggregate resources have been developed to be used for production of structural concrete for national land conservation and infrastructure improvement. In Chiba prefecture which is adjacent to the Tokyo Metropolitan District where concrete is consumed in large quantities, 16,016m3 of natural aggregate resources were extracted in 2009.The national aggregate resources extracted in Chiba are mostly pit sand/gravel, and development of sand and gravel resources are accompanied by forest development which absorbs carbon dioxide. Therefore, promotion of revegetation on mined land is urgent issue in terms of suppressing global warming. Addressing this issue on Chiba prefecture which is major production area for aggregates will contribute to promotion of revegetation in aggregate mining sites in other prefectures, which face a similar issue.
    It has been pointed out that the main cause of plant death in mined land is low permeability, lack of nutrients, and soil compaction caused by heavy equipment. In this consideration, we aimed to improve soil physical properties on mined land and feed nutrients necessary for plant growth by making soil conditioner from dewatered sludge, which generated in the process of washing and classifying aggregates.

    The main operation of surface coal mining is basically the removal of topsoil and overburden in order to extract the coal. If the overburden rocks contain a significant amount of reactive sulfide minerals rather than alkali minerals, severe acid mine drainage (AMD) is likely to occur when they are exposed and react with oxygen and water. AMD development in the overburden dumps occurs via complex physical and chemical weathering reactions. The different rates of the various mineral weathering reactions within the overburden coupled with the local climate conditions (i.e. intervals of rainfall, temperature) may cause temporal changes to the drainage chemistry. Several studies have been conducted in order to recognize the heterogeneity of the overburden dumps with several purposes, such as those focusing on the field monitoring, large-scale testing and numerical methods. In this study, a series of field investigations, physical and geochemical laboratory characterizations were conducted in order to evaluate the internal physical structure and geochemical characteristics of the coal mine overburden dumps.

    In Japan, the land of large metropolitan areas is highly utilized in increasingly complex conditions; therefore, the underground area is used to establish social infrastructures because of difficulties to use on the ground. Even in the publicly used shallow strata such as road sections, social infrastructures including subways, water and sewage systems, electrical equipment, communications facilities, and gas pipelines have already been installed and are very congested. Nowadays, when urban infrastructures need to be constructed, the difficulty of using the ground or shallow strata will necessarily lead to the more frequent use of the deep strata.
    The general advantages of using the deep strata which will help maintain the quality of social capital include stability, earthquake resistance, constant temperature and humidity, and blockages of vibration and noise, all of which will not affect the view on the ground. The good quality of social infrastructure will be installed by taking advantages of the deep strata construction of social infrastructures. Consequently, the development of effective, appropriately designed utilization of the deep strata will be strongly encouraged.
    Generally used construction methods include open-cut, pipe jacking, and shield methods. In the past, even during constructing in the shallow strata, due to the neighboring construction it is difficult to secure road traffic, prevent construction hazards such as vibration and noise, and to also take steps to protect the existing congested underground installations. In addition, the pipe jacking method has been widely adopted as a general construction method owing to its recent marvelous technological development. However as to the pipe jacking, example of construction in the deep strata is few and study is insufficiency.
    From above, in this paper the applicability of pipe jacking method in the deep strata is discussed. Especially, a behavior of the tail-void which is considered important factor in pipe jacking construction is discussed.

    Wavelet analysis, as the typical represent of time-frequency analysis technique, has been extensively applied to vibration signal analysis, which is also a vital research subject in signal de-noising field. In this article, discrete wavelet transform is used to analyze the weak remote blasting signals and extract small features, also is applied emphatically in de-noising processing of blasting waves based on the theory of wavelet analysis. The optimal selection of wavelet function and existing practical problems are emphasized with amounts of waveforms aiming to obtain the excellent blasting signals. Time frequency characteristics, particle velocity and effect duration are discussed deeply. The results indicate that wavelet analysis to some extent has advantages on de-noising processing, and the signal to noise ratio is enhanced. The value of remote blasting waves in use is improved greatly.

    Comparing with the traditional limit equilibrium methods, a finite element method has some obvious advantages for analyzing slope stability. As a result, a strength reduction factor method based on the finite element theory is used widely. This paper represents the fundamental principle of the shear strength reduction approach for calculation of slope safety factor by means of finite element method. Also, the influence factors for the accuracy of the slope safety factor were discussed. It is found that the slope model should be built by using the six-node triangle type, and the element size ratio is 0.03, and it is recommended that the distance from the crest of the slope to the left boundary should be more than 2.5 times of the slope width; the distance from the toe of the slope to the right boundary should be at least 3 times of the slope width; and the distance from the toe of the slope to the bottom boundary should be at least 1.5 times of the slope height. The outcome shows that the simulation results by using optimal slope model have the high accuracy.

    The paper discusses preliminary study on design of rib pillar between open-pit slope and underground working in thick seams in Mae Moh lignite mine in Thailand. Mae Moh mine is currently operated as open pit mine and it is the largest open pit coal mine in Thailand. In the near future, however, the final pit limit of the mine will be reached and underground mining will be developed from the final highwall in the depth of 400-600 from the surface. However, due to the adverse geological and geotechnical conditions, such as weak mechanical properties of rock, extra-thickness (20-30 m) of coal seams, and huge final pit slope, various studies for future underground mine, including open pit slope stability, an applicable underground mining method, and effect of underground mining on open pit slope stability, etc., are being carried out at the present. In this study, it was investigated the response of pit slope in different extent of rib pillars, which is measured horizontally minimum distance from the open pit wall to underground mine, and in different size of panels and mining height, and the interaction between open pit slope and underground working. The investigation was conducted by means of numerical analyses using three dimensional finite difference code FLAC3D.

    Reclamation is an integral part of the mining operation with the ultimate aim is to restore disturbed land caused by surface mine operation to function according to its designation. Considering the importance of the mining reclamation, Indonesian government had issued several regulations concerning reclamation. Indonesian government regulation No 78/2010 concerning reclamation and mine closure stated that mining permit holder and special mining permit holder of exploration and production operation are obliged to reclaim the area until result satisfies the success criteria.
    The Minister of Forestry Regulation of Indonesia No.P.60/Menhut-II/2009 regarding guidance for assessment the success of forest reclamation mentioned that the assessment of reclamation success includes site preparation, erosion control, and re-vegetation. The reclamation area needs to be monitored periodically to identify the progress of reclamation and monitor the reclamation success and its success is dependent on many parameters. Hence, it is a significant challenge on how to manage and monitor multi parameter and multi temporal data.
    Taking account the matters mentioned above, this study therefore aims to design a geodatabase template for monitoring reclamation progress in Indonesian coal mining and ArcCatalog ArcGIS 9.3 software was used. The required data for building the geodatabase refers to Minister of Forestry Regulation No.P.60/Menhut-II/2009. The process of building the geodatabase template includes the following steps: collect and group dataset; design feature dataset, feature class and attribute; create geodatabase; and create database dictionary.
    According to the research result, geodatabase template is very promising for monitoring reclamation progress in Indonesian coal mining, it allows to monitor the reclamation progress periodically with easily.

    Lubrication can effectively reduce necessary thrust for over-cutting if a discrete layer of the lubricant is maintained between the pipe and the excavated soil. The lubricant must be designed to form a layer in the surrounding soil, be pressurized to overcome underground water pressure and stabilize the over-cutting area. The lubricant should fill the complete over-cutting area to minimize surface settlement. However, it has been clarified that for a commercial lubricant to be effective, the ingredients such as sodium and potassium should be eliminated. As a result, for a lubricant not to lose its function as a support against the overburdening pressure of an over-cutting area (hereinafter referred to as tail void) and to enable a reduction in thrust, it is necessary to develop a better quality lubricant that can overcome these problems as soon as possible.
    From this perspective, a lubricating material comprised of a mixture of surfactant and fly ash was developed. This report focuses attention on minimizing soil deformation. In particular, to stabilize the layer in tail void between the pipe and the excavated soil and to examine the characteristics of material attributes to avoid reduction in thrust, a variety of experiments were performed using both traditional lubricating materials and a new material mixed with fly ash.

    Much attention is paid to Mongolia, particularly, South Gobi as a new source of coal. Many countries such as Japan, Korea, USA, as well as nearby China and Russia are very interested in large scale coal mine projects, namely, Tavan Tolgoi project in South Gobi area where affluent and high quality coal deposits for steaming and metallurgical use are underlain. There is, however, a bottle neck by poorly developed infrastructure in South Gobi, which has for a long time prevented from coal mine development there. A couple of new coal mines have already been developed and coal has been mined in South Gobi. Considering environmental impacts from development of coal mines, the Department of Earth Resources Engineering, Kyushu University (DEREKU) has started a joint research program with Mongolian University of Science and Technology (MUST).
    This paper describes some problems in development of coal mines in South Gobi, considering social, economical and environmental factors based on the field surveys.

    Almost of the coal resources are produced from open cut mines in Indonesia. Mining operation of open cut mines gives serious impacts on surrounding environment. Therefore, it can be said that appropriate rehabilitation program for environmental protection should be considered.
    As one of the most important environment impact, acid mine drainage (AMD) problem is concerned in Indonesian coal mines. And the cover layer system is suggested and implemented for prevention of AMD. The concept of this system is covering over Potentially Acid Forming (PAF) by Non Acid Forming (NAF) as barrier layer to minimize water and/or oxygen infiltration. In current research, application of flyash (FA) is also discussed to prevent AMD generation. And finally, revegetation of the surface applied the cover layer system should be considered.
    This paper describes the relationship between AMD problem and the effect for vegetation from waste rock or FA.

    Reclamation is an integral part of the mining activities to restore disturbed land by mining operation in order to be safe, stable and productive land according to its capability and designation. Considering the importance of reclamation in mining activities, Indonesia Government had issued several regulations related to mine reclamation. Monitoring of reclamation area should be conducted periodically to assess the success of reclamation and to monitor the progress of reclamation for continual improvement. Monitoring of reclamation area by collecting data and information directly in the field will be very time consuming. Thus, there is a need of methods that can periodically monitor a wide reclamation area rapidly and accurately. Purpose of this study is to monitor reclamation progress in Indonesia coal mining using remote sensing and geographic information system. Based on research result, multi temporal satellite images can be applied for identification reclamation area change, vegetation density change and correlation between vegetation density (NDVI) value and age of vegetation planting.

    In modern mining industry, blasting is the rock excavation and fragmentation technique most widely adopted because of its economical and efficient aspects. However, a ground vibration induced by blasting may give serious impacts on surrounding environment and has to be paid much attention in the mining operation. Peak Particle Velocity (PPV) is one of the important parameters related with ground vibration. Hence, the prediction of PPV is very important in order to design an appropriate blasting standard and minimize its environmental impacts.
    This paper discusses the applicability of the numerical simulation to the prediction of PPV in limestone quarries based on the results of field experiments. In addition, the effects of rock properties and geological conditions on ground vibration are also discussed by means of numerical simulation in this study.

    A great deal of coal will be left under the final end-walls in Chinese open pit mines because of lower slope angle in shovel-truck mining technology system and larger mining depth. In traditional surface mining system, the coal under the end-walls will be buried by the inner dumping site, and the coal resources are normally discarded. Considering these situations, this paper describes end-wall mining system in order to recover the residual coal based on the geological conditions of coal seams at Chinese open pit coal mines. The outcome shows that coal pillar width will be larger with the increase of mining openings width. However, the coal recovery ration can be improved. To improve the recovery ratio, we should increase the mining width as much as possible when the conditions permit. According to the theoretical and numerical simulation results, the optimal mining width should be 40 m and the pillar width is 10m in the studied coal mine.

    In longwall mining system, gateroads must be well supported in order to withstand high abutment load created by a retreating longwall face. Standing supports such as steel aches or three-piece sets (props and bars) along with the necessary struts and lagging have been traditionally used in underground coal mines in Japan due to severe strata conditions. Therefore, coal mines tried to introduce rockbolting system so as to raise productivity levels and reduce operating costs.
    This paper describes rockbolting technology applied to longwall gateroads in Japan and discusses rockbolting application to poor strata conditions.

    Mechanical pipe jacking methods are adopted for no-dig infrastructure-constructions because of reliability and safety. In especially, high density mud slurry pipe jacking method had much actual results under unique works. Nowadays these methods are desired any diversification under working surrounding. That is, “Direct-Arrival-Method to the existing underground structure”, “Sharp radical curve pipe jacking works, for example ,U・L turning curved pipe lines”, “Recovery function for un-expectation objects in the ground”, and “Rectangular (Box Culvert) pipe jacking method” are demanded.
    On the other hands, the works in big cobble and hard rock layer are increasing. Under these conditions, the long life inspection of cutting bits is the most important problem. In generality, at life-time over, cutter bits are exchanged in the shield machine or outside pit with bad conditions. However, there are some troubles in these conditions. This report shows the works with long distance pipe line construction through the big cobble and hard-rock layer without replacing cutting bits.

    The paper discusses preliminary study on the effect of underground mining on large open pit slope
    stability in Mae Moh coalfield in Thailand. Mae Moh mine is currently operated as open pit mine and
    it is the largest open pit coal mine in Thailand. In the near future, however, the final pit limit of the
    mine will be reached and underground mining will be developed from the final highwall in the depth of
    400-600 from the surface. However, due to the adverse geological and geotechnical conditions, such
    as weak mechanical properties of rock, extra-thickness (20-30 m) of coal seams, and huge final pit
    slope,various studies for underground mine are being carried out at the present. In this study, it was
    investigated for appropriate distance between open pit wall and underground mine, response of pit
    slope in different extent of rib pillars, which is measured horizontally minimum distance from the
    open pit wall to underground mine,and panels, and different mining height, and the interaction
    between open pit slope and underground working. The investigation was conducted by means of
    numerical techniques using three dimensional finite difference code FLAC3D.

    Coal mining companies in Indonesia are obliged to perform reclamation effort to achieve
    sustainability post mining land use and as much as possible to restore after mined land to the initial
    condition. The main factor that normally affects the reclamation success is the loss of soil fertility due
    to soil erosion. Soil erosion causes the loss of top soil layer which has a very important role in plant
    growth because this layer contains the highest concentration of organic matters and microorganisms.
    Soil erosion is influenced by climate properties, soil properties, topographic properties, cropping
    management factor and human intervention in conservation practice factor. The aim of this research is
    to analyze effect of soil properties and slope to the soil erosion in Indonesia coal mining reclamation
    area using rainfall simulator. This research was conducted using three types of soil texture including
    clay, clay loam and silty clay loam; also conducted using three types of slope including 2o, 15o, and
    30o. According to research result, the amount of soil loss increased with the increasing angle of slope
    and increasing of clay content.

    As the increasing of coal utilization, requirement on re-utilization of coal combustion ash (CCA) was also increased. In the mine site, having considered the some advantage characteristics of CCA, co-placement with overburden rock in the overburden dumping area of mining site is to be one potential alternative to be implemented. In this paper, the potential use of CCA from a specific site power plant as a layer in the dry cover system was studied. According to the quality of discharged water and measured-oxygen concentration within the column under the influences of local climate, the experiment indicates some advantages of CCA utilization such as higher on pH, alkalinity and higher capacity to prevent oxygen diffusion into the column. These results offer a promising technique to re-utilize CCA in controlling acid mine drainage (AMD) generation from potentially acid forming overburden rock.

    In the field of ground improvement works, mechanical soil mixing is an indispensable technique and is carried out using auger type machine with mixing paddles attached to the drilling rods. This type of machine excavates the soil in-situ horizontally and cannot mix the cut soil vertically. On the other hand, chain saw type machines are developed and put in use evaluating its vertically cut and mixed soil cement rectangular column body. This paper analyses the cutting mechanism of the chain saw type machine which moves horizontally while cutting and mixing the soil in-situ with cementing material. The machine is moved forward by shifting rams installed on surface and driven by a hydraulic power unit. The cutting force of each radial bit is given by the unit while the normal force is by the rams on surface. Considering the number of bits working along the face from top surface to bottom of the machine, it is essential but difficult to secure sufficient normal forces of each bit. This paper discribes type of cutting bit, bit array and cutting direction for the sake of stable indentation of the bit to the ground.

    Dumping areas represent a significant investment and a long-term liability in the form of a potential source of pollution or stability hazard. Now, the failure of dumping area occurs frequently in the open pit mines. Therefore, greater effort must be paid for design and formation of appropriate dumping area to mitigate environmental effects and promote long-term reclamation. However, the systematic researches on the stability of dumping area are quite few.
    In order to establish the guidelines for the appropriate design of dumping site, our research group is conducting a series of fundamental studies.
    First of all, the field investigation was conducted in Heidaigou open pit mine of China to understand the current dumping system and its conditions and problems. Based on the results of field investigation, a series of laboratory tests were conducted to understand the mechanism of forming dumping piles under different conditions.
    This paper describes the overview of field investigation in Heidaigou mine and discusses the formation of dumping piles under different conditions based on the results of a series of laboratory tests.

    Indonesia produced 306 Mt of saleable coal in 2010 which was mined by almost 100% of surface mining method. Rapid increase in production by surface mining year by year has brought strong concerns of sustainable supply ability of coal with current quality level in future, due to deepening mining location with increasing stripping ratio, decreasing coal reserve with high quality in the currently operating mines and constraints on development of surface mine by environmental impact. Thus, development of underground coal mines has been expected in Indonesia recently. However, there are only a few underground coal mines operating with small scale at present due to several technical problems for development of underground coal mines such as weak roof and floor conditions, coal quality being likely to cause spontaneous combustion, less stability of coal seam thickness and so on.
    This paper discusses the measures to overcome the technical problems based on the underground mining technology in Japan.

    Natural aggregate resources have been developed to be used for production of structural concrete for national land conservation and infrastructure improvement. In Chiba prefecture which is adjacent to the Tokyo Metropolitan District where concrete is consumed in large quantities, 16,016m3 of natural aggregate resources were extracted in 2009.The national aggregate resources extracted in Chiba are mostly pit sand/gravel, and development of sand and gravel resources are accompanied by forest development which absorbs carbon dioxide. Therefore, promotion of revegetation on mined land is urgent issue in terms of suppressing global warming. Addressing this issue on Chiba prefecture which is major production area for aggregates will contribute to promotion of revegetation in aggregate mining sites in other prefectures, which face a similar issue.
    It has been pointed out that the main cause of plant death in mined land is low permeability, lack of nutrients, and soil compaction caused by heavy equipment. In this consideration, we aimed to improve soil physical properties on mined land and feed nutrients necessary for plant growth by making soil conditioner from dewatered sludge, which generated in the process of washing and classifying aggregates.

    Indonesia produces almost of coal resources by surface mining and some environmental impacts can be expected. Soil erosion is one of an important factor among these impacts to monitor and/or manage rehabilitation after the mining operation has finished. Therefore, the condition of soil erosion in the post mining surface area has to be estimated accurately in order to succeed rehabilitation. As one of an efficient method for prediction of soil loss, the Universal Soil Loss Equation (USLE), as modified for forestlands by Dissmeyer and Foster (1984), is the most widely used method of predicting soil loss in forestry. However, when considering the application of this equation in post mining surface area, a sufficient consideration is needed because the condition of these areas is very different from that of forestry.
    In this study, the compering investigation between the results from laboratory tests and the results from USLE was conducted in order to predict soil loss in the mining field.

    In Japan when urban infrastructures need to be constructed, the difficulty of utilizing the ground or shallow strata will necessarily lead to the more frequent use of the deep strata.
    The common construction methods are open-cut, pipe jacking, and shield methods.
    In recent years a new pipe jacking method has been established that can be adapted to 20 m below the ground or more. Using the method, the drivage machine and the jacking pipe continue to move an underground until the completion of the driving. Therefore an over-cutting area (so-called tail-void) must be formed to lower the friction between the ground and the pipe. The tail-void is filled with lubrications. However, because the stress release of the ground continues to advance when the tail-void is formed, there are some challenges required to cope with the stability of the surrounding ground. In order to utilize the pipe jacking method in the deeper strata layers, the theory, analysis and installation of tail-void have to be systemized, and such systematic data must be stored.
    Therefore, the conditions of tail-void in the deep pipe jacking method are discussed using numerical analyses.

    Current peak particle velocity (PPV) prediction model assume site-specific K is proportional to the energy of explosive charge on explosive column. Site-specific K is assumed symmetry for all transmission paths. In fact, free-face of bench blasting produces large obstacle of wave energy propagation in the surrounding of explosive column, which, in turn, implies dissimilarity in distribution of wave energy at adjacent of surface of bench. In regard to this circumstance, assumption that wave energy distributes symmetrically for all pathways at adjacent of explosive column near-surface wall of bench blasting is unrealistic. This paper discusses a new approach in development of PPV prediction model by considering characteristic of K and B at adjacent of source of explosive near-wall of bench blasting.

    At open pit coal mines, a large amount of coal is left around the end-walls due to the stability of slope, mining boundary, and so on. In order to increase coal recovery of open pit coal mines ,the application of a highwall mining system for residual coal around the end-walls is proposed. This mining method can be extracted the coals abandoned around end-walls efficiently. However, in order to introduce this mining system to open pit coal mines safely and efficiently, the adequate mining design considering not only stability of end-walls but also coal recovery ratio has to be investigated.
    This paper discusses the applicability of a highwall mining system for recovering plenty of coal left around the end-walls and its appropriate design by means of numerical analysis.

    A great deal of coal will be left under the final end-walls in Chinese open pit mines because of lower slope angle in shovel-truck mining technology system and larger mining depth. In traditional surface mining system, the coal under the end-walls will be buried by the inner dumping site, and the coal resources are normally discarded. Considering these situations, this paper describes end-wall mining system in order to recover the residual coal based on the geological conditions of coal seams at Chinese open pit coal mines. The mining system can improve economic benefits by exploiting haulage and ventilation roadways from the exposed position of coal seams, and utilizing the existing transportation systems. In order to investigate the pillar design methodology in end-wall mining system, several empirical formulas and methods were discussed based on the actual geological mechanical properties of coal and rock in Chinese open pit mine. The outcome shows that the coal pillar width calculated by Salamon formula may serve as an important reference for pillar design in end-wall mining system. According to the theoretical and numerical simulation results, end-wall mining system can increase the coal recovery from residual coal resources around end-wall and reduce the effect of underground mining operation on slope stability.

    In the last few decades, the utilization of coal to generate electricity was rapidly increasing. Consequently, the production of coal combustion ash (CCA) as a by-product of coal utilization as primary energy sources was increased. The physical and geochemical characteristics of CCA were site-specific which determined by both inherent coal-source quality and combustion condition. The physical, chemical and mineralogical characteristic of a coal combustion ash (CCA) from a site specific power plant was investigated and the leachate characteristic of some scenario on the co-placement the CCA with coal-mine waste rock was evaluated. The physical properties such as specific gravity, dry density, porosity and particle size distribution were determined. From the chemical Characterization it is found that the CCA samples are enriched predominantly in silica (SiO2), alumina (Al2O3) and iron oxides (Fe2O3), along with a little amount of CaO, and fall under the Class C fly ash category. In addition, the mineral phases identified in the samples were quartz, mullite, magnetite, and hematite. Co-placement experiment with mudstone waste rock shows that the CCA, though it has limited contribution to the decreasing permeability, has important contributed to increase the quality of leachate through releasing higher alkalinity. Moreover, addition of CCA did not affect to the increase of the trace metal element in the leachate. Hence, utilization of CCA by co-placement with coal mine waste rock in the dumping area is visible to be implemented.

    Chain Conveyor Cutter (CCC) is a chainsaw-type machine and originally developed for the construction of underground walls and/or ground improvements. CCC was developed from the accumulated technology of coal mining, combining the cutting technology of a shearer and the fuctions of chain conveyor. The CCC can cut harder soils and soft rocks, and vertically mixes the cut soils/rocks with cementing material selected through the discharging port installed at the bottom of the machine. In Indonesia, highwall mining trials have already been conducted in several coal mines. However, full-scale and regular operations have not been done yet due to the ground and machine control issues from their geological conditions. In order to overcome these problems, the application of CCC to highwall mining systems was proposed, and its applicability and technical issues to be solved were investigated in this research. This paper discribes the characteristics of CCC system and discusses the application of CCC to highwall mining systems.

    The presence of water and oxygen are some of the important factors influencing the oxidation rate of sulfide minerals within overburden dumps. In overburden dumps, the availability of water and oxygen is strongly controlled by the physical structure of the dump, as well as the surface climate and geochemical reaction within the dump.
    In this study, a series of field investigations, physical and geochemical laboratory characterization were conducted in order to evaluate internal physical structure and geochemical characteristics of coal mine overburden dumps. The study found that a multi bench structure consisting of 10 m height of inter-fingered slope layer is formed as the effect of the end dumping technique. In addition, overburden material was characterized to have high clay content and low durable characteristic when interact with water. These characteristics couple with mining equipment traffic has result in a compacted layer on the surface of each bench lift which then controls the groundwater flow path within the dumps. Moreover, the geochemical characteristics were random, alternating among potentially acid forming and non acid forming materials within the inter-fingered layer. Those alternate geochemical characteristics may control acidification-neutralization reaction of infiltrated water, precipitation of secondary mineral and determines the quality of the overburden dump drainage, subsequently. The internal structure formed and the spatial heterogeneity of geochemical characteristics in overburden dump controls the acid drainage inhibition process within the dumps.

    Acid mine drainage (AMD) has become one of the most concern environmental impact in the mining
    industry in the world. AMD may raise number potential problems for the environment and human
    beings such as the impact on the aquatic life and communities in the downstream environment
    resulting from acidity and dissolved metals, and affect on groundwater quality and difficulties in revegetation.
    Waste dump of sulfide containing rock is one of potential AMD source since it was content huge
    amount of ready oxidized sulfide mineral due to its exposure to air and water. Application of dry cover
    system is counted as one of the best practices in a sustainable prevention of acid mine drainage of the
    waste rock dump at surface coal mine. However, the implementation of dry cover system in the field
    practice has faced several obstacles due to the limited amount of cover-materials. The nature of

    Indonesia is the second largest coal exporter to Japan, accounting for about 30 M tons annually. They
    produced about 250 M tons in 2010, over 99% of which being from open-cut mines. However, the
    conditions of surface mining are becoming worse each year: the stripping ratio is increasing, approaching
    the economic ratio and the infrastructure for coal transportation from inland mining areas is insufficient
    for such intense mining operations. To meet the demand for coal in Indonesia and the rest of the world,
    underground mines have to be developed. At present, there are only five small underground mines, three
    of which are old and the other two have only recently begun mining operations. However, severe ground
    control problems have been occurring regularly, roof falls in particular. Unfortunately, mining engineers
    and/or miners in this mine do not have a lot of experiences, expertise and know-how concerning the
    operations of underground coal mines.
    Under these situations, since 2001, Japan has started a ‘five-year plan for coal technology transfer’ to fill
    Japan’s moral obligation as the largest coal importer in the world. The research team was organized and
    conducted on-site investigation in order to develop new underground coal mine in Indonesia.
    This paper describes the geotechnical issues for development of underground coal mine in Indonesia.

    Many problems result when coal mine shafts are built in complicated geological conditions and serious shaft lining ruptures have often occurred in the eastern part of China since 1987. Several types of treatment methods are used for shaft lining reinforcement, such as the grouting method, sets of wall reinforcement method and stress-relief slot method; based on analysis of these methods and the mechanism of shaft lining rupture, a new treatment method is proposed for shaft lining treatment with an underground continuous impervious curtain (UCIC). In this study, the mechanism of shaft lining rupture was analyzed using numerical simulation, the current treatment methods were also analyzed, and then the various conditions of the UCIC built around the shaft lining were analyzed and the effect of the UCIC method was discussed. The results show that the lowering of water level in an aquifer can result in shaft lining rupture, and the new method has the effect to reduce and transform the stress concentration, and is able to reinforce shaft lining rupture in actual application.

    A number of coal deposits exist in the south of Zambia and coal mining have been operated for decades. Zambia coal mining has supported Zambian industries including cement manufacturing, copper smelting and electric power. Especially, usage of coal for power generation is marked with expectation in terms of energy balance and beneficial use of low rank coal treated as waste rock. Though these expectations drive new coal mining operations forward, it is necessary that control of environmental issues reported in mining operations, including acid mine drainage problems, is achieved.
    First, in order to realize the issues and situation of acid mine drainage in Zambian coal mines, water analysis in the field and laboratory waste rock characterizations was conducted. Next, a laboratory column leach test was conducted to discuss the application of AMD prevention in the dumping sites. This paper describes the results of field investigations and the column leach test and proposes a new system of AMD prevention from the state of mining operation based on the results.

    A new underground mining trial has been conducted in East Kalimantan, Indonesia in order to investigate the possibility of technical challenges of underground coal mine under weak geological condition, especially the application and management of rock bolting system. The application of rock bolting system for Indonesian underground coal mines had been attempted for a long time, but they had not been success yet. In this mining trial, even though roof falls have occurred within the working area, the bolted roadways showed a reasonable stability over time. Moreover, the comprehensive monitoring system has been installed in order to monitor the ground behaviour and its characteristics. This application of comprehensive monitoring system has enhanced the ability to increase the level of support and to react to changing/deteriorating conditions. In addition, monitoring data has allowed a quantitative assessment for future full scale mining.
    This paper discusses the applicability of roof bolting system and its ground control management under weak strata condition in Indonesia by means of site investigations and numerical analysis.

    In longwall mining system, gateroads must be well supported in order to withstand high abutment load created by a retreating longwall face. Standing supports such as steel aches or three-piece sets (props and bars) along with the necessary struts and lagging have been traditionally used in underground coal mines in Japan due to severe strata conditions. Therefore, coal mines tried to introduce rockbolting support system so as to raise productivity levels and reduce operating costs.
    This paper describes Japanese underground mining system, an overview of the rockbolting technology that was applied to longwall gateroads in Japan and discusses some problems involved in using bolting.

    Coal mining industry gives many benefi ts for Indonesia including contribution in total Indonesian GDP. Most of
    coal mines in Indonesia are open pit mining method which disturbs large area of land. One of open pit mining impact is damage land and related to soil erosion occurrences it will degrade land by top soil loses. Indonesia Government has issued mine closure regulation to encourage mining industry provide post mining land use. Determination of post mining land use should be considering the physical land properties including soil properties, topography and climate properties. The land evaluation process using GIS enables effective, easy and systematic determination of post mining land use.

    Development of aggregate resources for use in structural concrete has been
    encouraged in Japan to support infrastructure improvement and national land
    conservation. Natural aggregate is a valuable resource necessary for sound
    economic development and its importance is growing. However, against the
    backdrop of the ongoing depletion of resources, growing concern over nature
    conservation and increasingly tightened control over resource use, the supply of
    natural aggregates such as sea/river/pit sand and sea/river gravel has been
    decreasing.
    The number and scale of public works and construction of buildings have
    been decreased due to the recent recession and the critical public opinion about
    public works. However, the necessary public works have been done as in the
    past. The lack of high quality aggregates has become a serious problem in Japan.
    Dredging of sea floor sand and development of new sand quarries for securing
    good quality sand have become the target of criticism from the viewpoint of
    environmental protection.
    This paper describes the present situation and future prospects of
    environmental and safety measures in suburban aggregate mines in Japan.

    According to the previous research, it is found that the thickness of cover is mostly less than 100 m for highwall mining system. However, for most of the Chinese surface coal mines, the mining depth is over 150 m; on the other hand, the shovel-truck is the most common mining technology. As a result, a lot of residual coal will be remained around end-walls. Considering these facts, the calculated methodology of highwall mining system under thick cover is presented in this paper. Meanwhile, numerical simulation of highwall mining system under thick cover was carried out. The outcome shows that the calculated methodology for pillar stability of highwall mining system under thick cover presented in this paper is acceptable. In other words, the highwall mining system is feasible to extract the residual coal around end-walls in Chinese surface coal mines. Thus, not only coal recovery ratio can be improved, but also can increase the production life of surface coal mines in China.

    Lubrication can effectively reduce the needed thrust if a discrete layer of lubricant is maintained between a pipe and the excavated soil. A lower frictional force allows greater jacking lengths to be achieved. The reduction of frictional stress around the pipe strongly affects the efficiency of lubrication injection. The lubricant must be designed to form a layer in the surrounding soil, be pressurized to overcome ground water pressure and stabilize the over-cutting area. The lubricant should also fill the over-cutting area completely to minimize surface settlement. However, for a commercial lubricant to be effective, it has been suggested that ingredients such as sodium and potassium be eliminated. As a result, in order that a lubricant does not lose its function as a support against the overburden pressure of an over-cutting area and to enable a reduction in thrust, a higher quality lubricant which can overcome these problems must be developed as soon as possible. In this paper, in order to examine the characteristics and behaviour of a material developed as a lubricant and backfilling for a deeper strata excavation system such as a pipe jacking, a fundamental investigation is performed and the various results are discussed.

    Much attention is paid to Mongolia, particularly, South Gobi as a new source of coal. Many countries such as Japan, Korea, USA, as well as nearby China and Russia are very interested in large scale coal mine projects, namely, Tavan Tolgoi project in South Gobi area where affluent and high quality coal deposits for steaming and metallurgical use are underlain. There is, however, a bottle neck by poorly developed infrastructure in South Gobi, which has for a long time prevented from coal mine development there. A couple of new coal mines have already been developed and coal has been mined in South Gobi. Considering environmental impacts from development of coal mines, the Department of Earth Resources Engineering, Kyushu University (DEREKU) has started a joint research program with Mongolian University of Science and Technology (MUST).

    The presence of water and oxygen are some of the important factors influencing the oxidation rate of sulfide minerals within overburden dumps. In the overburden dumps, the availability of water and oxygen is strongly controlled by the physical structure of the dump, as well as the surface climate and geochemical reaction within the dump. In this study, made up of a series of field investigations, physical and geochemical laboratory characterizations were conducted in order to evaluate the internal physical structure and geochemical characteristics of coal mine overburden dumps. As the result of a series of analysis, alternate geochemical characteristics may control the acidification-neutralization reaction of infiltrated water, the precipitation of secondary minerals and may subsequently determine the quality of the overburden dump drainage. The internal structure formed and the spatial heterogeneity of geochemical characteristics in the overburden dumps controls the acid drainage inhibition process within the dumps.

    Buried pipelines that have sagged can result in damage to welded joints, disconnections and so on. Performance can also be affected with stagnation or stoppage of flow, which can lead to major secondary problems, such as caved-in roads or effluent leakage. To overcome these problems, various methods have been proposed and used for the restoration of flow performance and fixing damaged sections of underground pipelines without the need for excavation. However, there are not many methods available that do not require excavation for repairing reduced flow performance and stoppages, or pipeline damage caused by sagging, which is thought to be the major contributor to this type of damage. The authors provide a report on construction methods and examples that do not require excavation, but instead use a system of grouting for the ground, surrounding the buried pipeline, to aid in the repair of the pipeline position, which can actually improve the surrounding foundations.

    現在,インドネシアにおける石炭生産量の99%は露天掘りによって採掘されている。しかしながら,現在いくつかの炭鉱が坑内展開を実施あるいは計画中であるが,稼行中の露天採掘炭鉱での深部化と剥土費の増加によるコスト上昇,露天採掘可能埋蔵量の減少,指定森林区域における露天採掘の禁止など今後,増加し続ける石炭需要を満たすためには露天採掘から坑内採掘への展開は必要不可欠かつ急務であるといえる。そこで,露天掘り鉱山の最終残壁からパンチマイニングシステムを用いた坑内展開を提案し,この坑内展開の可否や最適な採掘設計について数値解析を用いて種々検討した結果について述べる。

    インドネシアでは石炭のほとんどが露天掘りにより採掘されており,開発後には大規模な荒廃した土地が採掘跡地として形成される。開発によって形成された荒廃した採掘跡地では,熱帯雨林の消失や土砂流出による河川の汚濁など深刻な環境問題が引き起こされるため,環境修復のための効果的な対策を開発初期段階より検討・策定する必要がある。インドネシアは熱帯雨林気候に属しており,多量の降雨と開発地域特有の地質状況によって露天掘り鉱山開発に伴い酸性鉱廃水 (Acid Mine Drainage: AMD) 問題が深刻化している。AMD 問題はインドネシア露天掘り石炭鉱山において重要視されている環境問題の一つあり,鉱山会社においてもAMD 抑制対策のための廃石の埋め戻しシステムや水質管理に対して様々な取り組みを行っている。また,採掘跡地は生態系や環境保全といった理由から最終的に地表面は植物で覆われる必要があるが,近年では農作物の栽培や乳牛および肉牛の放牧等の産業用途のための採掘跡地の利用も同時に検討されている。本報告ではインドネシア露天掘り石炭鉱山における環境修復の現状および今後の展望に関して大規模鉱山の操業を例に述べる。

    岩戸鉱山では一次クラッシャーに投入できる起砕鉱の粒径は500mm 以下である。したがって,起砕鉱の中から500mm 以上を選別し,ブレーカーにより500mm 以下に小割する作業が必要となる。現発破規格では,500mm 以上の起砕鉱の割合が多く,小割作業が採掘費を増加させる一要因となっていることから,それを削減することが課題となっている。一般に,発破による起砕鉱の粒径は,その規格のみならず岩盤状態( 亀裂,強度),地質など様々な要因に影響を受ける。したがって,上記課題解決のために,岩盤状態を考慮した最適な発破規格を導き出すことを目的とし,粒度解析,亀裂評価,力学試験を実施した。まず,現発破規格で発破を行い,起砕鉱粒度分布の解析を行った。また,岩盤状態がその粒度分布に与える影響を検討するため,発破箇所ごとに,発破前切羽壁面の亀裂評価,起砕鉱の力学試験を実施した。その後,発破規格を変更して,同様の粒度解析,亀裂評価,力学試験を実施した。最後に,その結果および各作業のユニット・コストを元に,最適な発破規格を採用することによる粒度分布の変化が採掘費に与える改善効果を試算した。

    我が国の天然骨材資源は,国土の保全や社会基盤整備等のための構造物の骨格を成すコンクリートの材料として開発が行われてきた。骨材の大消費地である首都圏の需要に応えている千葉県では,平成24 年実績で8,618 千m 3 の天然骨材を生産している。骨材生産の洗浄・選別工程で発生する廃棄物の脱水ケーキは,現状ではほぼ全量が採取場内で埋立処分されているが,地表近くに埋立処分されると,透水性悪化により跡地緑化に大きな影響を及ぼす。跡地緑化に影響を及ぼさない深度に脱水ケーキを埋立処分するためには,十分な深度を持つ処分場が確保されるまで脱水ケーキを一時保存する場所が必要であるが,採取場面積の限られている砂利採取鉱山では,十分な場所を確保することが困難な状況となっている。本検討では,二次元応力解析プログラムPhase2 を用いて,安定かつ狭い面積で実現可能な脱水ケーキダンピングサイト設計について解析的検討を行った。

    Acid Mine Drainage (AMD) problem is considered as one of the serious problems in mining operation in the world. This problem is generated due to sulfide minerals in waste rocks. Sulfide minerals are very commonly included in any types of crustal rocks, resulting in AMD and a negative impact on the ecosystem. In this research, some experiments were conducted with the rocks sampled in the open pit coal mine in Indonesia to understand the effects of the rock condition on acidic water generation. The result indicated that wetting and drying process affected the disintegration of rocks caused by both physical and chemical factors in the rock sample. Hence, AMD generation is promoted due to both factors while waste rocks are stored in tailings in the current system. It suggests that the system for waste rock management should be improved to prevent AMD generation.

    Most of coal is produced from open-cut mines in Southeast Asian countries. However, the conditions of their surface mines are worsening each year: the stripping ratio is increasing, approaching economic ratio and the regulation of environmental protection. To meet the demand for coal, underground mines have to be developed in the near future. Under these circumstances, the development of new coal mines from open-cut highwalls are being planned in Southeast Asian countries. Moreover, some of the Southeast Asian mines have thick coal seams. However, if the conventional mining systems and designs introduced in US, Australia and European countries are applied, several geotechnical issues can be expected due to the mines’ weak geological conditions. From these backgrounds, this paper proposed a punch multi-slice mining system with stowing for thick coal seam under weak geoligical conditions and discussed its applicability and suitable design by means of numerical analysis.

    Mangkalapi-2 Pit is a pit in Batulicin coal mine site, South Kalimantan, operated by PT Arutmin Indonesia. The mining operation in this pit has come to the last stage and will proceed to the closure stage in the near future. According to the mine closure plan, Mangkalapi-2 will be directed to be recreational lake for the community. Currently, the water quality in the Mangkalapi-2 pond is relatively good with pH above 6.5. However, considering the characteristics of lithology in the area which indicate the capacity to generate acid drainage, hence a study to assess the future condition of pit lake water quality is necessary.
    The study began with rock and water sampling in Mangkalapi pit and its surrounding. Rock samples were employed for the geochemical composition while the water samples were analyzed for some quality parameters. The simulation on post-mining water quality was conducted using the PHREEQC software. The laboratory kinetic test using Free Draining Column Leach Test was also performed for some selected rock samples.
    Simulation was conducted for different scenarios based on the assumed distribution of sulfide minerals in the pit wall. The results of simulation have indicated the potential of acid water with pH value range from 4.48 to 5.10. Scenario of mixing of leachates from different leach columns containing different type of rock samples was also being simulated for comparison.

    A detailed study to propose new design support systems for underground mine was carried out in this paper. Serious shotcrete failures have often occurred in Cibaliung Underground Gold Mine in Indonesia. Three main rock types, quartz vein as ore body, andesite-breccia altered by clorite-adularia on foot wall abundance and andesite-breccia altered by smectite-illite dominant on hanging wall rock. The cut and fill mining method was selected for this mine in accordance with the geometry of vein, topographic specifications, and annual production rates. Excavation size, distance between stope and decline, depth, and the impact of fault will influence the induced stresses. Different depths in multiple excavations were analyzed in this study especially on decline area. In this study, the engineering properties of rock masses were defined from field and laboratory test for each rock types. Support systems for decline were designed based on the suggestions of the Rock Mass Rating (RMR) system and the Q system of rock mass classification. Induced stress on different levels were calculated to define Stress Reduction Factor (SRF) and applied to predict the support system by Q system.

    Opencast mine is a typical mining method to product coal in Indonesia and a large scale of disturbed land occurs in this method. Therefore, an appropriate revegetation process must be designed to complete the rehabilitation in the disturbed area. The basic concept of revegetation in opencast mines is the recovery of the nature and ecosystem and the creation of a self-sustaining land surface in the disturbed area involved the creation of conditions suitable for the establishment. However, the productive use in the large scale of disturbed land is considered in recent years. In this study, application of Paper Mulberry as productive use in the disturbed area was discussed by means of several laboratory and field tests. It was revealed that 1) hot-water treatment in 80℃ for 10 seconds is the most effective treatment to improve germinating rate (more than 80%), 2) Paper Mulberry can grow up under the rehabilitation area in Indonesian opencast mine and the growth rate can be improved by the earlier transplanting to the field after seed germination.

    Crack initiation and propagation are key factors affecting rock deformability, strength and hydraulic properties. Fracture toughness is a parameter, which indicates crack initiation or the onset of propagation of a material. A number of standard methods have been proposed to determine the ModeⅠfracture toughness of rock. They include those based on short rod specimen, chevron bend specimen and cracked chevron-notched Brazilian disc specimen. The semi-circular bend (SCB) specimen was suggested in 1984 for testing mode I fracture toughness of rock. Recently, SCB specimen was extended and improved for many other applications by various researchers owing to inherent favorable properties such as its simplicity, minimal requirement of machining and the convenience of testing that can be accomplished by applying 3-point compressive loading using a common laboratory load frame though short rod (SR) specimen is recommended method by International Society for rock mechanics (ISRM). However, there are still rooms to consider for determining the fracture toughness of rock exactly by SCB specimen. This paper discusses the application of the SCB specimen for determining the fracture toughness of rock by comparison between the result of SCB specimen and SR specimen with Isahaya sandstone and Kimachi sandstone, and size effect using the SCB specimen.

    Indonesia produces over 350Mt of clean coal in 2012 and is the second largest coal exporter to Japan, accounting for 30 Mt/y. Almost of the coal produced is from open cut mines. Mining operation of open cut mines gives serious impacts on surrounding environment. Therefore, an appropriate rehabilitation program has to be taken into consideration when the mine plan is designed.
    Indonesia belongs to tropical rainforest climate and the average annual rainfall shows 2,000~4,000mm/year. One of major environmental problem occurred in rehabilitation area is soil erosion due to heavy rainfall. Soil erosion is easy to accelerate under the high rainfall level, especially in sharp cloudbursts such as squall.
    From series of investigation and discussion, the soil spread to rehabilitation area shows different soil composition due to mixing overburden during soil stripping and stockpiling process. Moreover, it can be expected that this condition could be critical factor for the risk of soil erosion. Therefore, adequate rehabilitation process to limit soil erosion has to be considered such as establishment of erosion control structures and rapid growing cover crop species.

    The number of coal mines with coal and gas outburst is shooting up with mining depth increasing in China. Mining protective coal seam is one of the most effective technologies preventing coal and gas outburst for mining high-gas multi-seams with low permeability. However, the difficulty of controlling roadway stability in upper protected seams above the gob jumps after mining lower protective coal seam. Based on the problem of surrounding rock stability control for roadway in the overlying protected seam of high-gas multi-seams through ascending stress-relief mining in Huainan mining area, the numerical simulation model is established according to actual engineering to analyze the redistribution of stress during roadway excavation and mining lower protective coal seam, and influence of bolt support on fissure and displacement fields of surrounding rock. Support technique of “three-high” bolt support system combined with pre-stressed anchor cable beam structure is put forward that is successfully applied in Guqiao Coal Mine. Field measurement has proved that the deformation of surrounding rock tended to be stable in 41 days after the support scheme was implemented in the roadway that was excavated in the upper protected seam in 150 days after mining the lower protective seam.

    Although the extraction in the stress relaxation zone of deep multi-seam coal mining is relative safely, unnatural accidents still occur occasionally and sometimes threaten worker’s life security seriously. To explore the primary factor that caused these issues, the characteristics of lateral stress reconstruction and floor failure behavior in interlayer rock mass were surveyed based upon a series of field investigations. And both the redistribution of principle stress and phenomenon of interlayer rock failure were analyzed by numerical simulation. Then by the infinitesimal strain method, two types of infinitesimal analysis models in vertical and horizontal direction respectively were created to explore the reason of floor failure behavior and the mechanism of localized stress concentration. And the impact of localized stress concentration in interlayer rock mass induced by the extracted liberated seam on the subsequent extraction of protected seam was discussed finally. Main findings indicate that a certain extent of localized stress concentration in interlayer rock mass induced by the increased lateral stress results in these accidents. Reconstructed lateral stress provides the mechanical conditions for rock element failure; meanwhile the rock failure behavior further aggravates localized stress concentration in its lower half. Based upon the impact of localized stress concentration in interlayer rock mass, an extraction of protected seam is divided into safe, risky and general types, which helps the reliable mining in deep multiple coal seams.

    Coal production in Mongolia has rapidly increased with the development of new coal mines; from 5 million tons in 2000 to 25 million tons in 2012. However, in accordance with the rapid development of coal mines in Mongolia, geotechnical, operational and environmental issues have occurred such as the stability of highwall/lowwall and dumping/stock piles, the maintenance of transportation system, etc.
    Especially, the geotechnical investigation and data are insufficient in main coal deposits. This is main cause of current problems such as slope slides, failures and collapses occurred at most open pit coal mines. In order to develop an appropriate mine design, these investigations have been conducted. In addition, the geological data has to be collected and urgent issues for further coal mine development were discussed.
    This paper describes the current conditions of Narynsukhait open pit coal mine and then discusses its geotechnical issues.

    Mae Moh mine is the largest open-pit lignite mine in Thailand. In this mine, the development of underground mine from final highwall is considered after the surface mining operation is finished. Longwall mining is a common method for extracting coal from various thickness of coal seam. However, due to unfavorable geological conditions such as weak strata and huge final pit slopes, various preliminary studies on the introduction of underground mining systems have been conducted so far. This paper discusses the applicability of longwall mining system and its suitable design by means of three-dimensional numerical modeling: FLAC3D.

    Acid Mine Drainage (AMD) is one of the serious problems which are caused in the mining operation and it may impact on the ecosystem due to low pH. Considering the fact that the dumping site is a large stockpile of waste materials and it is always exposed to the local climatic conditions, this area can be deemed as one of the sources of AMD. Therefore, it is important to prevent the occurrence of AMD from dumping site after constructng it. This paper describes the results of field investigation and laboratory experiment about AMD problem, and discuss the relevancy between the inner structure of dumping site and the occurrence of AMD.

    The semi-circular bend (SCB) specimen was suggested in 1984 for testing mode I fracture toughness of rock. Recently, SCB specimen was extended and improved for many other applications by various researchers due to ease in handling though short rod (SR) specimen is recommended method. However, there are still rooms to consider for determining the fracture toughness of rock exactly by SCB specimen. This paper discusses the application of the SCB specimen for determining the fracture toughness of rock by comparison between the result of SCB specimen and SR specimen, and size effect using the SCB specimen.

    In modern mining industry, the blasting technique is one of the most adopted techniques for rock excavation and fragmentation due to its economical and efficient aspects. However, compared with other methods, the use of explosives in blasting is limited by law as it may have a severe impact on the surrounding environment such as vibration, noise and dust. Especially, a ground vibration induced by blasting has to be paid much attention in the mining operation as it may give an obvious impact on the surrounding facilities and buildings and in many established safe level blasting criteria, the ground vibration level is characterized by using three parameters; duration, amplitude (peak particle velocity :PPV) and frequency. Current studies on the blast-induced ground vibration focus on two parameters amplitude and frequency that suggested by USBM when the concerned subject is structure, i.e.. Hence, the control of PPV and dominant frequency are very important in order to design an appropriate blasting standard and minimize its environmental impacts.
    This paper discusses the propagation behavior of blast-induced ground vibration in the open pit mine and study by means of field experiments and numerical simulation. In addition, the methods for reduction of blast-induced ground vibration are also discussed by means of numerical simulation in this study.

    The EGAT Mae Moh lignite mine is the largest open-pit coal mine in Thailand. The total geological and economical reserves of Mae Moh coal field are approximately 1,140 Mt and 825 Mt, respectively. The annual production is 12 Mton, which represents 90 % of the total coal production in Thailand, and tends to decrease gradually. In this mine, the development of underground mine from final highwall is considered after the open-pit mining operation is finished. Longwall mining is one of the common methods for extracting coal in various thickness of coal seams and is much more effective, productive and safer than any other mining methods. The productivity of longwall mining is potentially high because it is basically a continuous operation requiring fewer workers and allowing a high production rate to be sustained. Due to unfavorable geological and geotechnical conditions such as weak strata and huge final pit slopes in this mine, however, various studies on the introduction of underground mining systems have been conducted so far. Optimizing boundary and/or safety pillars and panel design for both safety and economics is a key part of planning longwall mines. This paper discribes the applicability of the longwall mining system from final highwall and its suitable design taking the slope stability into consideration by means of three-dimensional explicit finite-difference program FLAC3D producted by ITASCA.

    Generally, grouting in dam construction is the construction method that soil voids and crack around borehole is filled by pressurized injection of grouting material such as cement and permeability or mechanical characteristics of rock mass is improved.
    It was previously mentioned that backfilling material plays an important role as a support against overburden pressure after finishing construction. Therefore most of the underground deformations caused by the injection may be caused by changing the condition of surrounding rock masses and numbers of cracks. That is why the discussion of appropriate injection methods, etc. in preparation for such changes is inevitable. From this point of view, the new backfilling material can be developed for several kinds of soil conditions in this paper.

    Mining operation of open cut mines gives serious impacts on surrounding environment such as disturbance of the tropical rainforest, the pollution of surface and/or ground water, subsidence and erosion. Under such situations, rehabilitation is one of the important and considerable topics for an environment protection. Adequate rehabilitation program will solve these environmental issues and recover the ecosystem. The basic concept of rehabilitation in open cut mines is the creation of a stable and self-sustaining land surface in post mine surface involved the creation of conditions suitable for the establishment and permanent development of a dense cover of vegetation. In usual, a lot of open cut mine keep the topsoil individually in the natural forest during soil stripping process and spread the topsoil to rehabilitation area for success of revegetation. However, there are some considerable points for dealing with topsoil in situ such as the soil properties and severe compaction by heavy equipment. Therefore, the proper topsoil management has to be considered for establishment of vegetation in post mine surface.
    This paper describes the current situations of rehabilitation at one of open cut coal mine in Indonesia and the results of investigation about the characteristics of soil spread in rehabilitation area as plant base.

    Acid Mine Drainage (AMD) is one of the serious problems which are caused in the mining operation. The main factors which cause the problem are H2O and O2 and sulfide minerals such as iron pyrite. Sulfide minerals are usually contained in any type of crustal structure, and there is a possibility of generation of AMD in any area. The problem may impact on the ecosystem or people in the surrounding area since the acidic water is low-pH and usually contains high level of heavy metals. Therefore, it is important to prevent the problem in mining operation. A passive treatment is low-cost and easy to maintain for dealing with AMD problems. In a passive remediation, the study on behavior of AMD generation and elution behavior of heavy metals in a laboratory is necessary before introducing it in the mine site to construct it designed for the situation. Moreover, elution behavior may be changed by management of waste rock, as a practical matter, acidic water generates due to a rough treatment of waste rock in some mine sites. Therefore, in this research, the study on the waste rock was conducted for predicting a quality of acidic water by characterizing the rock and for elucidating effects of treatment of waste rock to elution behavior of heavy metals. This paper describes the results of laboratory experiments such as a column test and a sequence extraction for predicting elution behavior of heavy metals and an occurrence of acidic water, and treatment of waste rock for effective countermeasure for dealing with acidic water for a long term is discussed.

    インドネシアは年間約3,000万tの石炭を我が国に輸出している日本第2位の石炭輸入先である。インドネシアでは石炭のほとんどを露天掘り採掘により生産されているため、開発後の環境修復に向け、採掘跡地の再緑化を行う必要がある。本来、採掘跡地の再緑化の目的は自然系の回復であり、採掘跡地を自立した土地として再生することである。しかしながら、現在、農作物や繊維資源など産業用途のための採掘跡地の有効利用も考慮されつつある。
    そこで本報告では、良質な繊維資源としての有効利用が期待される植栽種としてカジノキ(Paper Mulberry)に着目した。我が国においてもカジノキの生育は確認されており、主に世界的に評価の高い高級和紙の原料として利用されている。また、カジノキは早期生育で繁殖能力が高いため、適切に採掘跡地に植栽することで採掘跡地から継続的な繊維資源の供給が可能となり、新しい産業の確立にもつながると考えられる。
    以上の背景から、インドネシア露天掘り鉱山の採掘跡地におけるカジノキの生育に関して各種室内および現場試験により検討を行ったので報告する。

    In Japan when urban infrastructures need to be constructed, the difficulty of utilizing the ground or shallow strata will necessarily lead to the more frequent use of the deep strata. The common construction methods are open-cut, pipe jacking, and shield methods. In recent years a new pipe jacking method has been established that can be adapted to 20 m below the ground or more. Using the method, the drivage machine and the jacking pipe continue to move an underground until the completion of the driving. Therefore an over-cutting area (so-called tail-void) must be formed to lower the friction between the ground and the pipe. The over-cutting area is filled with lubrications. However, because the stress release of the ground continues to advance when the over-cutting area is formed, there are some challenges required to cope with the stability of the surrounding ground. In order to utilize the pipe jacking method in the deeper strata layers, the theory, analysis and installation of over-cutting area have to be systemized, and such systematic data must be stored. Therefore, the conditions of over-cutting area in the deep pipe jacking method are discussed using numerical analyses. Moreover, a lubricating material comprised of a mixture of surfactant and fly ash was developed for the application of pipe jacking in deep strata.

    The construction of sewerage with non‐excavation technology includes both the
    renewal method and the pipe jacking method. When carrying out works in urban areas
    in Japan, the pipe jacking method, with which increasing numbers of pipelines are
    constructed, has been replaced by the conventional open cut method. This is due to
    difficulties such as congested underground installation, features of roads making
    them prone to traffic jams, problems with traffic control, the impact of noise and
    vibration on nearby houses, and the limited work area which needs to be excavated
    from the road’s surface when excavating the open cut method. In addition, a large
    diameter of 3,000 mm or more has been promoted in recent years. On the other hand,
    many sewage‐pipes renewal technologies that have later become superannuated have
    been developed. The technology for renewing superannuated or damaged tubes consists
    of two methods; replacing an existing tube with new tube by breaking the existing
    tube, and lining the inside of an existing tube.
    Our paper will discuss the application of the construction method for infrastructure
    using pipe jacking in Japan. Moreover, some examples of this method for pipe renewal
    systems will be shown.

    In the last decade, the price of gold continues to rise, that generate mining activities increase linearly. Indonesia is one of the top ten gold producers in the world. One of the gold mines in Indonesia is Cibaliung Underground Gold Mine where located in west part of Java Island. Follows the trend, increasing production will be further target of this company.
    The type of ore of Cibaliung underground gold mine is vein with low sulphidation. Basaltic andesite, andesite porphyritic, andesite breccia and vein breccia are constituent rocks and altered by smectite and chlorite. The mining method that carried out this mine is relative similar with some underground gold mines in Indonesia (Pongkor and Nusa Halmahera Mining) i.e. cut and fill mining method. For underground mine, geological information is a key to design such as geological structure, rock mass classification, discontinuities, and other geological parameters. They are linked each other. Four types support system has been recommended in Cibaliung mine. However some cracks still occurred in shotcrete support system along decline access. This paper discusses about support design of cut-and-fill mine method at underground gold mine. Commercial software namely Phase2® is used to review the stability of support system. Rock mass classification includes Q system and RMR, and laboratory tests were carried out to determine parameter for numerical modeling analysis.

    Due to large mining depths, sometimes the stripping ratio becomes so large that some coal around the end-wall cannot be mined considering the economic factors at large-scale open pit coal mines in China. Also, to meet requirements of haul roads in the end-wall transporting system, wide transportation benches have to be left, which makes the slope angle of the end-wall slope smaller. Consequently, a large quantity of coal has to be left under the final end-wall slope. For these remaining coal resources, they will be buried again by the inpit dumping site and are impossible to be extracted once more in future. Therefore, how to recover the remaining coal around the end-wall slope with a safe and efficient extraction system before they are buried by the inpit dump is very urgent and valuable research for open pit coal mines in China.

    This paper describes a fundamental study on deep underground pipe construction using a pipe jacking method. This study is aimed to discuss the probability of failure under constructing pipe in deep underground. The study has been carried out using a numerical simulation method. The 3D-σ was used to analyze the failure proximity. The failure proximity is based on the failure criterion of Mohr-Coulomb. This study was carried out by changing some influential parameters of the condition of the pipe and surrounding ground i.e. overburden, thickness of pipe, friction resistance, and aberration from the center of distributed force in order to grasp a response of the failure proximity. The simulation result shows that the failure proximity of the pipe rises with increasing overburden, friction resistance and aberration from the center of the distributed force, while on the other hand the failure proximity reduces by increasing thickness of the pipe.

    Dumping area consists of the artificial slope which had been piled up by the mining waste granular. Dumping operation is one of the important works in open-pit mines. Overburden is stripped and waste soil/rock is transported to dumping area in order to expose and extract coal seams. Dumping operation is to transport waste rock from mining working face to dumping areas, and then form benches for slope stability and rehabilitation. This work spends much cost and represents a significant investment. Waste embankments usually have little if any practical use and may represent a long-term liability in the form of a potential source of pollution or stability hazard. Because of economic considerations, a risk of slide and a potential of its environmental impacts, dumping sites must be designed carefully.
    However, the systematic researches on the stability of dumping sites are quite few and the large scale landslides still occur in the dumping sites. For instance, on October 29, 1991, a large slide which volume was about 10 Mm3 was occurred in the south external dumping site of Antaibao open pit mine in China. This slide caused 6 fatalities and many facilities loss. At present, a greater effort must be paid for the design and formation of appropriate dumping sites in order to save the investment, maintain the stability of dumping sites, mitigate the environmental impacts, and promote a long-term reclamation.
    Moreover, in dessert area for instance north-west China and Mongolia, the dumping material is “loess” and landslides and subsidence often occur in their dumping sites. One of the major causes is the characteristics of loess. The strength of loess changes dramatically due to its water content and it becomes to be low under wet condition. The systematic researches on the stability of dumping sites of loess are also quite few because the property of loess is very unique.
    This paper describes the present conditions of dumping sites in open pit coal mines and then discusses the formation mechanism of dumping piles under different conditions based on the results of laboratory tests.

    Indonesia produces over 350Mt of clean coal in 2012 and is the second largest coal exporter to Japan, accounting for 30 Mt/y. Almost of the coal produced is from open cut mines. Mining operation of open cut mines gives serious impacts on surrounding environment. Therefore, an appropriate rehabilitation program has to be taken into consideration when the mine plan is designed. The basic concept of rehabilitation in open cut mines is the creation of a stable and self-sustaining land surface in post mine surface involved the creation of conditions suitable for the establishment and permanent development of a dense cover of vegetation. Hence, the soil characteristics in rehabilitation area and adequate selection of species to plant in there have to be considered.
    This paper describes the current situations in rehabilitation area at one of open cut coal mine in Indonesia and then discusses the application of Paper Mulberry as one of effective species planted in post mine surface based on the laboratory tests.

Waste embankments usually have little if any practical use and may represent a long-term liability in the form of a potential source of pollution or stability hazard. Because of economic considerations, a risk of slide and a potential of its environmental impacts, dumping sites must be designed carefully.
    However, the systematic researches on the stability of dumping sites are quite few and the large scale landslides still occur in the dumping sites. For instance, on October 29, 1991, a large slide which volume was about 10 Mm3 was occurred in the south external dumping site of Antaibao open pit mine in China. This slide caused 6 fatalities and many facilities loss. At present, a greater effort must be paid for the design and formation of appropriate dumping sites in order to save the investment, maintain the stability of dumping sites, mitigate the environmental impacts, and promote a long-term reclamation.
    Moreover, in dessert area for instance north-west China and Mongolia, the dumping material is “loess” and landslides and subsidence often occur in their dumping sites. One of the major causes is the characteristics of loess. The strength of loess changes dramatically due to its water content and it becomes to be low under wet condition. The systematic researches on the stability of dumping sites of loess are also quite few because the property of loess is very unique.
    This paper describes the present conditions of dumping sites in open pit coal mines and then discusses the formation mechanism of dumping piles under different conditions based on the results of laboratory tests.

    Tunnel drivage machines, such as the shied machine, are now widely applied for the construction of underground space. In recent years, the distance of their construction span has been increasing and the shield tunneling system can be applied for ground that contains cobble stones and gravel soil. Therefore, the application of a shield drivage machine has become wider due to their advanced technology. However, once the conventional cutter bit hits with cobble stone and/or a boulder stone, the cutter bit fails and the cutting efficiency decreases dramatically or is completely lost. Therefore, the improvement of the impact resistance of their cutter bit is one of the major research topics for a shield tunneling system.
    This paper describes the multi-layer structure bits developed in our research and discusses the impact resistance and suitable design by means of laboratory tests and numerical simulation.

    The Mae Moh mine is located in Mae Moh district, Lampang province, about 630 kilometers north of Bangkok, Thailand. This mine is operated by EGAT (Electricity Generating Authority of Thailand), and it is the largest open-pit lignite mine in Thailand. The total geological and economical lignite reserves of the Mae Moh coal field are approximately 1,140 million tons and 825 million tons, respectively. The annual production is about 16 million tons, which represents 70 % of the total coal production of Thailand. All of the lignite produced from the mine is supplied to the 2,400 MW Mae Moh power plant, which is providing 15% of the total electricity demand of Thailand. 347 MT of lignite has been produced, and the remaining future reserve is about 478 MT (as of 2010). In the near future, the open pit limit will be reached and underground mine will be developed from the depth of 400-600 m from the surface. However, due to the problems such as poor geological conditions, extra thickness of coal seams (20-30 m thickness) and weak mechanical properties of rock, various studies, such as final open pit stability, an applicable underground mining system for Mae Moh mine are being conducted at the present. In this paper, it is discussed the response of pit slope in different extent of rib pillars, which is measured horizontally minimum distance from the open pit wall to underground mine, and in different size of panels and mining height, and the interaction between open pit slope and underground working by means of numerical analyses using three-dimensional finite difference code FLAC3D.

    In Japan, the land of large metropolitan areas is highly utilized in increasingly complex conditions; therefore, the underground area is used to establish social infrastructures because of difficulties to use on the ground. Even in the publicly used shallow strata such as road sections, social infrastructures including subways, water and sewage systems, electrical equipment, communications facilities, and gas pipelines have already been installed and are very congested. Nowadays, when urban infrastructures need to be constructed, the difficulty of using the ground or shallow strata will necessarily lead to the more frequent use of the deep strata.
    The general advantages of using the deep strata which will help maintain the quality of social capital include stability, earthquake resistance, constant temperature and humidity, and blockages of vibration and noise, all of which will not affect the view on the ground. The good quality of social infrastructure will be installed by taking advantages of the deep strata construction of social infrastructures. Consequently, the development of effective, appropriately designed utilization of the deep strata will be strongly encouraged.
    Generally used construction methods include open-cut, pipe jacking, and shield methods. In the past, even during constructing in the shallow strata, due to the neighboring construction it is difficult to secure road traffic, prevent construction hazards such as vibration and noise, and to also take steps to protect the existing congested underground installations. In addition, the pipe jacking method has been widely adopted as a general construction method owing to its recent marvelous technological development. However as to the pipe jacking, example of construction in the deep strata is few and study is insufficiency.
    From above, in this paper the applicability of pipe jacking method in the deep strata is discussed. Especially, a behavior of the tail-void which is considered important factor in pipe jacking construction is discussed.

    The main operation of surface coal mining is basically the removal of topsoil and overburden in order to extract the coal. If the overburden rocks contain a significant amount of reactive sulfide minerals rather than alkali minerals, severe acid mine drainage (AMD) is likely to occur when they are exposed and react with oxygen and water. AMD development in the overburden dumps occurs via complex physical and chemical weathering reactions. The different rates of the various mineral weathering reactions within the overburden coupled with the local climate conditions (i.e. intervals of rainfall, temperature) may cause temporal changes to the drainage chemistry. Several studies have been conducted in order to recognize the heterogeneity of the overburden dumps with several purposes, such as those focusing on the field monitoring, large-scale testing and numerical methods. In this study, a series of field investigations, physical and geochemical laboratory characterizations were conducted in order to evaluate the internal physical structure and geochemical characteristics of the coal mine overburden dumps.

    In Japan, the number and the scale of public works and construction of buildings have been decreased due to the recession and the critical public opinion about public works. However, the necessary public works have been done as same as before.
    Development of aggregate resources for use in structural concrete has been encouraged in Japan to support infrastructure improvement and national land conservation. Natural aggregate is a valuable resource necessary for sound economic development and its importance is growing. However, against the backdrop of the ongoing depletion of resources, growing concern over nature conservation and increasingly tightened control over resource use, the supply of natural aggregates such as sea/river/pit sand and sea/river gravel has been decreasing.
    Natural aggregate resources have been developed to be used for production of structural concrete for national land conservation and infrastructure improvement. In Chiba prefecture which is adjacent to the Tokyo Metropolitan District where concrete is consumed in large quantities, 16,016m3 of natural aggregate resources were extracted in 2009.The national aggregate resources extracted in Chiba are mostly pit sand/gravel, and development of sand and gravel resources are accompanied by forest development which absorbs carbon dioxide. Therefore, promotion of revegetation on mined land is urgent issue in terms of suppressing global warming. Addressing this issue on Chiba prefecture which is major production area for aggregates will contribute to promotion of revegetation in aggregate mining sites in other prefectures, which face a similar issue.
    It has been pointed out that the main cause of plant death in mined land is low permeability, lack of nutrients, and soil compaction caused by heavy equipment. In this consideration, we aimed to improve soil physical properties on mined land and feed nutrients necessary for plant growth by making soil conditioner from dewatered sludge, which generated in the process of washing and classifying aggregates.

    Rock blasting is the rock excavation technique most widely adopted in the various fields of the mining and construction industries because of its economical and efficient aspects.
    However, the application of blasting technique is limited by law because it may have a serious impact on surrounding environment such as ground vibration, noise and dust. Especially, ground vibration may cause the damage to the surrounding structures. Thus, mining companies which apply the blasting technique have to control the blast-induced ground vibration in order to minimize or eliminate the possibility of damage to nearby structures or to reduce complaints from neighbors.
    As many researches have studied on blasting techniques and its impact on the surrounding environments, several equations and methods for prediction of blast-induced ground vibration have already been proposed so far. Most of them adopt the Peak Particle Velocity for evaluation the degree of blast vibration. Each particle in the rock mass vibrates in a complicated motion, which is approximately elliptical motion in several cycles with varying amplitudes. The highest velocity during this motion is called as Peak Particle Velocity (PPV). However, the general prediction equation and/or method have not been developed yet because the different rock parameters and ground conditions have an obvious impact on elastic wave propagation.
    From these points of view, the 2-D numerical simulation method has been developed and evaluated by means of the results of field experiments in this study. In addition, a case study has also been conducted by using this numerical simulation in order to discuss the effects of ground conditions on blast vibration in quantity.

    Dumping area consists of the artificial slope which had been piled up by the mining waste granular (Guangjin Wang, 2011). Dumping operation is one of the important works in open-pit mining operation. Overburden is stripped and waste soil/rock is transported to dumping area to expose and extract coal seams. Dumping operation is to transport waste rock from mining working face to dumping areas, and then forming a bench for slope stability and rehabilitation. This work spends much cost and represents a significant investment. Waste embankments usually have little if any practical use and may represent a long-term liability in the form of a potential source of pollution or stability hazard. Because of economic considerations, a risk of slide and a potential of its environmental impacts, dumping sites must be designed carefully.
    However, the systematic researches on the stability of dumping sites are quite few and the large scale landslides still occur in the dumping sites. For instance, on October 29, 1991, a large slide was occurred in the south external dumping site of Antaibao open pit mine. The sliding volume has about 10Mm3, caused 6 person death and a huge property loss. At present, a greater effort must be paid for design and formation of appropriate dumping sites in order to save investment, maintain dumping sites stability, mitigate environmental effects, and promote long-term reclamation. Moreover, the dumping material is “loess” in dessert area for instance north west China and Mongolia where the seismic disasters such as land slide and subsidence occur. The strength of loess is high under dry condition. On the other hand, it becomes to be low under wet condition. The systematic researches on the stability of dumping sites of loess are also quite few because the property of loess is very unique. This paper describes the field investigation conducted in Heidaigou open pit mine where overburden material is loess in China and discusses the formation mechanism of dumping piles under different conditions based on the results of laboratory tests.

    Wavelet analysis, as the typical represent of time-frequency analysis technique, has been extensively applied to vibration signal analysis, which is also a vital research subject in signal de-noising field. In this article, discrete wavelet transform is used to analyze the weak remote blasting signals and extract small features, also is applied emphatically in de-noising processing of blasting waves based on the theory of wavelet analysis. The optimal selection of wavelet function and existing practical problems are emphasized with amounts of waveforms aiming to obtain the excellent blasting signals. Time frequency characteristics, particle
    velocity and effect duration are discussed deeply. The results indicate that wavelet analysis to some extent has advantages on de-noising processing, and the signal to noise ratio is enhanced. The value of remote blasting waves in use is improved greatly.

    Mine mineral demand in the world is increasing with the increase of mineral price and gold is one of the rapid increase mineral in a last decade. Geological information is a key for underground design. The most important parameters are geological structure, rock mass strength, main stress and strain, rock mass classification, discontinuities, etc. All of these may have impact on underground stability, if some are suitable, and only just one is troubled, it can be due to instability in underground.
    Cibaliung Underground Gold Mine (CUGM) is one of the gold mines in Indonesia were located in west part of Java in Indonesia. The type of ore is vein with low sulphidation epithermal deposit. This underground mine has two-shot targets; Cikoneng area, production is carried out predominantly through the hanging wall, and Cibitung area, production is primarily through the foot wall of the vein. In this paper, are discussed the fundamental information regarding the cracks those occur on shotcrete along Cikoneng Decline as a main road in CUGM. Field investigation such as scan line method, joint orientation measurement combine to secondary data is used for this study.

    Reclamation is an integral part of the mining operation with the ultimate aim is to restore disturbed land caused by surface mine operation to function according to its designation. Considering the importance of the mining reclamation, Indonesian government had issued several regulations concerning reclamation. Indonesian government regulation No 78/2010 concerning reclamation and mine closure stated that mining permit holder and special mining permit holder of exploration and production operation are obliged to reclaim the area until result satisfies the success criteria.
    The Minister of Forestry Regulation of Indonesia No.P.60/Menhut-II/2009 regarding guidance for assessment the success of forest reclamation mentioned that the assessment of reclamation success includes site preparation, erosion control, and re-vegetation. The reclamation area needs to be monitored periodically to identify the progress of reclamation and monitor the reclamation success and its success is dependent on many parameters. Hence, it is a significant challenge on how to manage and monitor multi parameter and multi temporal data.
    Taking account the matters mentioned above, this study therefore aims to design a geodatabase template for monitoring reclamation progress in Indonesian coal mining and ArcCatalog ArcGIS 9.3 software was used. The required data for building the geodatabase refers to Minister of Forestry Regulation No.P.60/Menhut-II/2009. The process of building the geodatabase template includes the following steps: collect and group dataset; design feature dataset, feature class and attribute; create geodatabase; and create database dictionary.
    According to the research result, geodatabase template is very promising for monitoring reclamation progress in Indonesian coal mining, it allows to monitor the reclamation progress periodically with easily.

    The paper discusses preliminary study on design of rib pillar between open-pit slope and underground working in thick seams in Mae Moh lignite mine in Thailand. Mae Moh mine is currently operated as open pit mine and it is the largest open pit coal mine in Thailand. In the near future, however, the final pit limit of the mine will be reached and underground mining will be developed from the final highwall in the depth of 400-600 from the surface. However, due to the adverse geological and geotechnical conditions, such as weak mechanical properties of rock, extra-thickness (20-30 m) of coal seams, and huge final pit slope, various studies for future underground mine, including open pit slope stability, an applicable underground mining method, and effect of underground mining on open pit slope stability, etc., are being carried out at the present. In this study, it was investigated the response of pit slope in different extent of rib pillars, which is measured horizontally minimum distance from the open pit wall to underground mine, and in different size of panels and mining height, and the interaction between open pit slope and underground working. The investigation was conducted by means of numerical analyses using three dimensional finite difference code FLAC3D.

    Comparing with the traditional limit equilibrium methods, a finite element method has some obvious advantages for analyzing slope stability. As a result, a strength reduction factor method based on the finite element theory is used widely. This paper represents the fundamental principle of the shear strength reduction approach for calculation of slope safety factor by means of finite element method. Also, the influence factors for the accuracy of the slope safety factor were discussed. It is found that the slope model should be built by using the six-node triangle type, and the element size ratio is 0.03, and it is recommended that the distance from the crest of the slope to the left boundary should be more than 2.5 times of the slope width; the distance from the toe of the slope to the right boundary should be at least 3 times of the slope width; and the distance from the toe of the slope to the bottom boundary should be at least 1.5 times of the slope height. The outcome shows that the simulation results by using optimal slope model have the high accuracy.

    Much attention is paid to Mongolia, particularly, South Gobi as a new source of coal. Many countries such as Japan, Korea, USA, as well as nearby China and Russia are very interested in large scale coal mine projects, namely, Tavan Tolgoi project in South Gobi area where affluent and high quality coal deposits for steaming and metallurgical use are underlain. There is, however, a bottle neck by poorly developed infrastructure in South Gobi, which has for a long time prevented from coal mine development there. A couple of new coal mines have already been developed and coal has been mined in South Gobi. Considering environmental impacts from development of coal mines, the Department of Earth Resources Engineering, Kyushu University (DEREKU) has started a joint research program with Mongolian University of Science and Technology (MUST).

    In longwall mining system, gateroads must be well supported in order to withstand high abutment load created by a retreating longwall face. Standing supports such as steel aches or three-piece sets (props and bars) along with the necessary struts and lagging have been traditionally used in underground coal mines in Japan due to severe strata conditions. Therefore, coal mines tried to introduce rockbolting system so as to raise productivity levels and reduce operating costs.
    This paper describes rockbolting technology applied to longwall gateroads in Japan and discusses rockbolting application to poor strata conditions.

    In modern mining industry, blasting is the rock excavation and fragmentation technique most widely adopted because of its economical and efficient aspects. However, a ground vibration induced by blasting may give serious impacts on surrounding environment and has to be paid much attention in the mining operation. Peak Particle Velocity (PPV) is one of the important parameters related with ground vibration. Hence, the prediction of PPV is very important in order to design an appropriate blasting standard and minimize its environmental impacts.
    This paper discusses the applicability of the numerical simulation to the prediction of PPV in limestone quarries based on the results of field experiments. In addition, the effects of rock properties and geological conditions on ground vibration are also discussed by means of numerical simulation in this study.

    Reclamation is an integral part of the mining activities to restore disturbed land by mining operation in order to be safe, stable and productive land according to its capability and designation. Considering the importance of reclamation in mining activities, Indonesia Government had issued several regulations related to mine reclamation. Monitoring of reclamation area should be conducted periodically to assess the success of reclamation and to monitor the progress of reclamation for continual improvement. Monitoring of reclamation area by collecting data and information directly in the field will be very time consuming. Thus, there is a need of methods that can periodically monitor a wide reclamation area rapidly and accurately. Purpose of this study is to monitor reclamation progress in Indonesia coal mining using remote sensing and geographic information system. Based on research result, multi temporal satellite images can be applied for identification reclamation area change, vegetation density change and correlation between vegetation density (NDVI) value and age of vegetation planting.

    Almost of the coal resources are produced from open cut mines in Indonesia. Mining operation of open cut mines gives serious impacts on surrounding environment. Therefore, it can be said that appropriate rehabilitation program for environmental protection should be considered.
    As one of the most important environment impact, acid mine drainage (AMD) problem is concerned in Indonesian coal mines. And the cover layer system is suggested and implemented for prevention of AMD. The concept of this system is covering over Potentially Acid Forming (PAF) by Non Acid Forming (NAF) as barrier layer to minimize water and/or oxygen infiltration. In current research, application of flyash (FA) is also discussed to prevent AMD generation. And finally, revegetation of the surface applied the cover layer system should be considered.
    This paper describes the relationship between AMD problem and the effect for vegetation from waste rock or FA.

    Mechanical pipe jacking methods are adopted for no-dig infrastructure-constructions because of reliability and safety. In especially, high density mud slurry pipe jacking method had much actual results under unique works. Nowadays these methods are desired any diversification under working surrounding. That is, “Direct-Arrival-Method to the existing underground structure”, “Sharp radical curve pipe jacking works, for example ,U・L turning curved pipe lines”, “Recovery function for un-expectation objects in the ground”, and “Rectangular (Box Culvert) pipe jacking method” are demanded.
    On the other hands, the works in big cobble and hard rock layer are increasing. Under these conditions, the long life inspection of cutting bits is the most important problem. In generality, at life-time over, cutter bits are exchanged in the shield machine or outside pit with bad conditions. However, there are some troubles in these conditions. This report shows the works with long distance pipe line construction through the big cobble and hard-rock layer without replacing cutting bits.

    Lubrication can effectively reduce necessary thrust for over-cutting if a discrete layer of the lubricant is maintained between the pipe and the excavated soil. The lubricant must be designed to form a layer in the surrounding soil, be pressurized to overcome underground water pressure and stabilize the over-cutting area. The lubricant should fill the complete over-cutting area to minimize surface settlement. However, it has been clarified that for a commercial lubricant to be effective, the ingredients such as sodium and potassium should be eliminated. As a result, for a lubricant not to lose its function as a support against the overburdening pressure of an over-cutting area (hereinafter referred to as tail void) and to enable a reduction in thrust, it is necessary to develop a better quality lubricant that can overcome these problems as soon as possible.
    From this perspective, a lubricating material comprised of a mixture of surfactant and fly ash was developed. This report focuses attention on minimizing soil deformation. In particular, to stabilize the layer in tail void between the pipe and the excavated soil and to examine the characteristics of material attributes to avoid reduction in thrust, a variety of experiments were performed using both traditional lubricating materials and a new material mixed with fly ash.

    A great deal of coal will be left under the final end-walls in Chinese open pit mines because of lower slope angle in shovel-truck mining technology system and larger mining depth. In traditional surface mining system, the coal under the end-walls will be buried by the inner dumping site, and the coal resources are normally discarded. Considering these situations, this paper describes end-wall mining system in order to recover the residual coal based on the geological conditions of coal seams at Chinese open pit coal mines. The outcome shows that coal pillar width will be larger with the increase of mining openings width. However, the coal recovery ration can be improved. To improve the recovery ratio, we should increase the mining width as much as possible when the conditions permit. According to the theoretical and numerical simulation results, the optimal mining width should be 40 m and the pillar width is 10m in the studied coal mine.

    Coal mining companies in Indonesia are obliged to perform reclamation effort to achieve
    sustainability post mining land use and as much as possible to restore after mined land to the initial
    condition. The main factor that normally affects the reclamation success is the loss of soil fertility due
    to soil erosion. Soil erosion causes the loss of top soil layer which has a very important role in plant
    growth because this layer contains the highest concentration of organic matters and microorganisms.
    Soil erosion is influenced by climate properties, soil properties, topographic properties, cropping
    management factor and human intervention in conservation practice factor. The aim of this research is
    to analyze effect of soil properties and slope to the soil erosion in Indonesia coal mining reclamation
    area using rainfall simulator. This research was conducted using three types of soil texture including
    clay, clay loam and silty clay loam; also conducted using three types of slope including 2o, 15o, and
    30o. According to research result, the amount of soil loss increased with the increasing angle of slope
    and increasing of clay content.

    As the increasing of coal utilization, requirement on re-utilization of coal combustion ash (CCA) was also increased. In the mine site, having considered the some advantage characteristics of CCA, co-placement with overburden rock in the overburden dumping area of mining site is to be one potential alternative to be implemented. In this paper, the potential use of CCA from a specific site power plant as a layer in the dry cover system was studied. According to the quality of discharged water and measured-oxygen concentration within the column under the influences of local climate, the experiment indicates some advantages of CCA utilization such as higher on pH, alkalinity and higher capacity to prevent oxygen diffusion into the column. These results offer a promising technique to re-utilize CCA in controlling acid mine drainage (AMD) generation from potentially acid forming overburden rock.

In traditional surface mining system, the coal under the end-walls will be buried by the inner dumping site, and the coal resources are normally discarded. Considering these situations, this paper describes end-wall mining system in order to recover the residual coal based on the geological conditions of coal seams at Chinese open pit coal mines. The mining system can improve economic benefits by exploiting haulage and ventilation roadways from the exposed position of coal seams, and utilizing the existing transportation systems. In order to investigate the pillar design methodology in end-wall mining system, several empirical formulas and methods were discussed based on the actual geological mechanical properties of coal and rock in Chinese open pit mine. The outcome shows that the coal pillar width calculated by Salamon formula may serve as an important reference for pillar design in end-wall mining system. According to the theoretical and numerical simulation results, end-wall mining system can increase the coal recovery from residual coal resources around end-wall and reduce the effect of underground mining operation on slope stability.

    Wavelet analysis, as the typical represent of time-frequency analysis technique, has been extensively applied to vibration signal analysis, which is also a vital research subject in signal de-noising field. In this article, discrete wavelet transform (DWT) is used to analyze the weak remote blasting signals and extract small features, and it is also applied emphatically in de-noising processing of seismic waves based on the theory of wavelet analysis. The optimal selection of wavelet function and existing practical problems are emphasized with amounts of waveforms aiming to obtain the excellent blasting signals. The results indicate that wavelet analysis has advantages on de-noising processing to a certain extent, and it can make the signal to noise ratio (SNR) enhanced. The value of remote blasting waves can be used more effectively.

    Indonesia produces almost of coal resources by surface mining and some environmental impacts can be expected. Soil erosion is one of an important factor among these impacts to monitor and/or manage rehabilitation after the mining operation has finished. Therefore, the condition of soil erosion in the post mining surface area has to be estimated accurately in order to succeed rehabilitation. As one of an efficient method for prediction of soil loss, the Universal Soil Loss Equation (USLE), as modified for forestlands by Dissmeyer and Foster (1984), is the most widely used method of predicting soil loss in forestry. However, when considering the application of this equation in post mining surface area, a sufficient consideration is needed because the condition of these areas is very different from that of forestry.
    In this study, the compering investigation between the results from laboratory tests and the results from USLE was conducted in order to predict soil loss in the mining field.

    Indonesia produces almost of coal resources by surface mining and some environmental impacts can be expected. Soil erosion is one of an important factor among these impacts to monitor and/or manage rehabilitation after the mining operation has finished. Therefore, the condition of soil erosion in the post mining surface area has to be estimated accurately in order to succeed rehabilitation. As one of an efficient method for prediction of soil loss, the Universal Soil Loss Equation (USLE), as modified for forestlands by Dissmeyer and Foster, is the most widely used method of predicting soil loss in forestry. However, when considering the application of this equation in post mining surface area, a sufficient consideration is needed because the condition of these areas is very different from that of forestry.
    In this study, the compering investigation between the results from laboratory tests and the results from USLE was conducted in order to predict soil loss in the mining field.

    Indonesia produced 306 Mt of saleable coal in 2010 which was mined by almost 100% of surface mining method. Rapid increase in production by surface mining year by year has brought strong concerns of sustainable supply ability of coal with current quality level in future, due to deepening mining location with increasing stripping ratio, decreasing coal reserve with high quality in the currently operating mines and constraints on development of surface mine by environmental impact. Thus, development of underground coal mines has been expected in Indonesia recently. However, there are only a few underground coal mines operating with small scale at present due to several technical problems for development of underground coal mines such as weak roof and floor conditions, coal quality being likely to cause spontaneous combustion, less stability of coal seam thickness and so on.
    This paper discusses the measures to overcome the technical problems based on the underground mining technology in Japan.

    Dumping areas represent a significant investment and a long-term liability in the form of a potential source of pollution or stability hazard. Now, the failure of dumping area occurs frequently in the open pit mines. Therefore, greater effort must be paid for design and formation of appropriate dumping area to mitigate environmental effects and promote long-term reclamation. However, the systematic researches on the stability of dumping area are quite few.
    In order to establish the guidelines for the appropriate design of dumping site, our research group is conducting a series of fundamental studies.
    First of all, the field investigation was conducted in Heidaigou open pit mine of China to understand the current dumping system and its conditions and problems. Based on the results of field investigation, a series of laboratory tests were conducted to understand the mechanism of forming dumping piles under different conditions.
    This paper describes the overview of field investigation in Heidaigou mine and discusses the formation of dumping piles under different conditions based on the results of a series of laboratory tests.

    In the field of ground improvement works, mechanical soil mixing is an indispensable technique and is carried out using auger type machine with mixing paddles attached to the drilling rods. This type of machine excavates the soil in-situ horizontally and cannot mix the cut soil vertically. On the other hand, chain saw type machines are developed and put in use evaluating its vertically cut and mixed soil cement rectangular column body. This paper analyses the cutting mechanism of the chain saw type machine which moves horizontally while cutting and mixing the soil in-situ with cementing material. The machine is moved forward by shifting rams installed on surface and driven by a hydraulic power unit. The cutting force of each radial bit is given by the unit while the normal force is by the rams on surface. Considering the number of bits working along the face from top surface to bottom of the machine, it is essential but difficult to secure sufficient normal forces of each bit. This paper discribes type of cutting bit, bit array and cutting direction for the sake of stable indentation of the bit to the ground.

    In Japan when urban infrastructures need to be constructed, the difficulty of utilizing the ground or shallow strata will necessarily lead to the more frequent use of the deep strata.
    The common construction methods are open-cut, pipe jacking, and shield methods.
    In recent years a new pipe jacking method has been established that can be adapted to 20 m below the ground or more. Using the method, the drivage machine and the jacking pipe continue to move an underground until the completion of the driving. Therefore an over-cutting area (so-called tail-void) must be formed to lower the friction between the ground and the pipe. The tail-void is filled with lubrications. However, because the stress release of the ground continues to advance when the tail-void is formed, there are some challenges required to cope with the stability of the surrounding ground. In order to utilize the pipe jacking method in the deeper strata layers, the theory, analysis and installation of tail-void have to be systemized, and such systematic data must be stored.
    Therefore, the conditions of tail-void in the deep pipe jacking method are discussed using numerical analyses.

    At open pit coal mines, a large amount of coal is left around the end-walls due to the stability of slope, mining boundary, and so on. In order to increase coal recovery of open pit coal mines ,the application of a highwall mining system for residual coal around the end-walls is proposed. This mining method can be extracted the coals abandoned around end-walls efficiently. However, in order to introduce this mining system to open pit coal mines safely and efficiently, the adequate mining design considering not only stability of end-walls but also coal recovery ratio has to be investigated.
    This paper discusses the applicability of a highwall mining system for recovering plenty of coal left around the end-walls and its appropriate design by means of numerical analysis.

    Current peak particle velocity (PPV) prediction model assume site-specific K is proportional to the energy of explosive charge on explosive column. Site-specific K is assumed symmetry for all transmission paths. In fact, free-face of bench blasting produces large obstacle of wave energy propagation in the surrounding of explosive column, which, in turn, implies dissimilarity in distribution of wave energy at adjacent of surface of bench. In regard to this circumstance, assumption that wave energy distributes symmetrically for all pathways at adjacent of explosive column near-surface wall of bench blasting is unrealistic. This paper discusses a new approach in development of PPV prediction model by considering characteristic of K and B at adjacent of source of explosive near-wall of bench blasting.

    Chain Conveyor Cutter (CCC) is a chainsaw-type machine and originally developed for the construction of underground walls and/or ground improvements. CCC was developed from the accumulated technology of coal mining, combining the cutting technology of a shearer and the fuctions of chain conveyor. The CCC can cut harder soils and soft rocks, and vertically mixes the cut soils/rocks with cementing material selected through the discharging port installed at the bottom of the machine. In Indonesia, highwall mining trials have already been conducted in several coal mines. However, full-scale and regular operations have not been done yet due to the ground and machine control issues from their geological conditions. In order to overcome these problems, the application of CCC to highwall mining systems was proposed, and its applicability and technical issues to be solved were investigated in this research. This paper discribes the characteristics of CCC system and discusses the application of CCC to highwall mining systems.

    Acid mine drainage (AMD) has become one of the most concern environmental impact in the mining
    industry in the world. AMD may raise number potential problems for the environment and human
    beings such as the impact on the aquatic life and communities in the downstream environment
    resulting from acidity and dissolved metals, and affect on groundwater quality and difficulties in revegetation.
    Waste dump of sulfide containing rock is one of potential AMD source since it was content huge
    amount of ready oxidized sulfide mineral due to its exposure to air and water. Application of dry cover
    system is counted as one of the best practices in a sustainable prevention of acid mine drainage of the
    waste rock dump at surface coal mine. However, the implementation of dry cover system in the field
    practice has faced several obstacles due to the limited amount of cover-materials. The nature of
    geological condition is to be the most control one while the other is mining method and equipment
    size should be taken into consideration to develop proper covering system.
    This paper describes the acid generation mechanism and its control, application of cover system and
    its problem being faced in Indonesian coal mine, and discusses the preliminary laboratory result of
    multi-layer cover system and proposed new covering strategy in order to obtain the effective solution
    of AMD.

    Indonesia is the second largest coal exporter to Japan, accounting for about 30 M tons annually. They
    produced about 250 M tons in 2010, over 99% of which being from open-cut mines. However, the
    conditions of surface mining are becoming worse each year: the stripping ratio is increasing, approaching
    the economic ratio and the infrastructure for coal transportation from inland mining areas is insufficient
    for such intense mining operations. To meet the demand for coal in Indonesia and the rest of the world,
    underground mines have to be developed. At present, there are only five small underground mines, three
    of which are old and the other two have only recently begun mining operations. However, severe ground
    control problems have been occurring regularly, roof falls in particular. Unfortunately, mining engineers
    and/or miners in this mine do not have a lot of experiences, expertise and know-how concerning the
    operations of underground coal mines.
    Under these situations, since 2001, Japan has started a ‘five-year plan for coal technology transfer’ to fill
    Japan’s moral obligation as the largest coal importer in the world. The research team was organized and
    conducted on-site investigation in order to develop new underground coal mine in Indonesia.
    This paper describes the geotechnical issues for development of underground coal mine in Indonesia.

    A new underground mining trial has been conducted in East Kalimantan, Indonesia in order to investigate the possibility of technical challenges of underground coal mine under weak geological condition, especially the application and management of rock bolting system. The application of rock bolting system for Indonesian underground coal mines had been attempted for a long time, but they had not been success yet. In this mining trial, even though roof falls have occurred within the working area, the bolted roadways showed a reasonable stability over time. Moreover, the comprehensive monitoring system has been installed in order to monitor the ground behaviour and its characteristics. This application of comprehensive monitoring system has enhanced the ability to increase the level of support and to react to changing/deteriorating conditions. In addition, monitoring data has allowed a quantitative assessment for future full scale mining.
    This paper discusses the applicability of roof bolting system and its ground control management under weak strata condition in Indonesia by means of site investigations and numerical analysis.

    In longwall mining system, gateroads must be well supported in order to withstand high abutment load created by a retreating longwall face. Standing supports such as steel aches or three-piece sets (props and bars) along with the necessary struts and lagging have been traditionally used in underground coal mines in Japan due to severe strata conditions. Therefore, coal mines tried to introduce rockbolting support system so as to raise productivity levels and reduce operating costs.
    This paper describes Japanese underground mining system, an overview of the rockbolting technology that was applied to longwall gateroads in Japan and discusses some problems involved in using bolting.

    The EGAT Mae Moh mine, producing lignite 16 million tons annually, is the largest open-pit lignite mine in Thailand. In the near future, however, the final pit limit of the mine will be reached and underground mine will then be developed from the final highwall in the depth of 400-600 m from the surface. However, due to the poor geological and geotechnical conditions of the mine, the various preliminary studies such as final pit wall stability, an applicable underground mining method, mine panel layout design and roof support system, etc. are being carried out at the present. In this paper, the application of rockbolt reinforcement system for the underground mine roadways is discussed by means of numerical method using two dimensional finite element code Phase2.

    A number of coal deposits exist in the south of Zambia and coal mining have been operated for decades. Zambia coal mining has supported Zambian industries including cement manufacturing, copper smelting and electric power. Especially, usage of coal for power generation is marked with expectation in terms of energy balance and beneficial use of low rank coal treated as waste rock. Though these expectations drive new coal mining operations forward, it is necessary that control of environmental issues reported in mining operations, including acid mine drainage problems, is achieved.
    First, in order to realize the issues and situation of acid mine drainage in Zambian coal mines, water analysis in the field and laboratory waste rock characterizations was conducted. Next, a laboratory column leach test was conducted to discuss the application of AMD prevention in the dumping sites. This paper describes the results of field investigations and the column leach test and proposes a new system of AMD prevention from the state of mining operation based on the results.

    Chain Conveyor Cutter (CCC) is a machine used for ground improvement. CCC is penetrated down to the ground excavating and vertically mixing the cut soil with cement slurry. The cut-off walls constructed by CCC, named as CCC Wall, are tight enough to prevent the water from passing through and from causing the groundwater pollution. CCC is effectively applicable to the mine site. This paper introduces actual working records and the characteristics of CCC.

    According to the previous research, it is found that the thickness of cover is mostly less than 100 m for highwall mining system. However, for most of the Chinese surface coal mines, the mining depth is over 150 m; on the other hand, the shovel-truck is the most common mining technology. As a result, a lot of residual coal will be remained around end-walls. Considering these facts, the calculated methodology of highwall mining system under thick cover is presented in this paper. Meanwhile, numerical simulation of highwall mining system under thick cover was carried out. The outcome shows that the calculated methodology for pillar stability of highwall mining system under thick cover presented in this paper is acceptable. In other words, the highwall mining system is feasible to extract the residual coal around end-walls in Chinese surface coal mines. Thus, not only coal recovery ratio can be improved, but also can increase the production life of surface coal mines in China.

    今日、都市開発事業において、深度の浅い空洞の開発、維持に関するニーズが急速に高まり、安全かつ効果的に空洞を開発、維持、管理するためには、深度の浅い空洞やその周辺領域の変形・破壊挙動を解明する必要がある。深度の浅い空洞の変形・破壊挙動は、空洞周辺に作用する重力の影響や不均質な地圧、地下水圧の影響が複雑に関係しているため、これらの要因を十分把握した上で厳密に検討しなければならない。筆者は1990年代より石炭鉱山の岩盤掘削に関する研究を行ってきたが、石炭鉱山の閉山に伴いそれまで培ってきた技術や蓄積してきた知見を資源開発の他分野に拡張するために推進工法に関わる研究を開始し、現在、推進工法を対象とした理論、実験および実測による検討を行っている。研究開始当時、泥水加圧式推進工法をはじめとする推進工法を研究テーマとして取り扱われた例は国内外とも極めて少なく、施工中に発生した様々な現象を未だ経験的により解決しているのが実状であったため、これの適用現場の安定性の評価、低推力推進メカニズム、低推力で推進できる泥水の開発などの3つの分野に分けて実験、実測および解析を行い、2007年ローマで開催された国際非開削技術協会でNO-DIGアワードを受賞した。本報告では、筆者がこれまで実施してきた研究状況、本研究テーマの課題、解決法などに絞って簡単にまとめた内容について示す。

    Grant type:Scientific research funding

    近年、エネルギー・鉱物資源の需要の高まりから、海洋底に賦存するメタンハイドレートやレアアース等の資源が注目されている。このことから、先導的実験として海底熱水資源開発時の環境擾乱抑制を目的とした無機系被覆材の適用に関する実地試験を行った。その結果、環境・採掘条件に見合った被覆材を開発するための基礎的知見を得ることが必要不可欠であることが分かった。海洋底鉱物資源を安全かつ最大限回収でき、資源開発に伴う環境負荷を抑制できる方法を世界に先駆けて開発し、国際的優位性を確立するために、本研究では、無機系被覆材を用いた環境低負荷型の海洋底鉱物資源採掘システムを確立すること目的とする。
