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.. |

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.. |

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.. |

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.. |

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.. |

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.. |

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.. |

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.. |

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.. |

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.. |

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. . |

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.

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. . |

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.. |

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 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. . |

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. . |

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.. |

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.

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.

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.

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. . |

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. . |

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.. |

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. . |

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 . |

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.. |

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. . |

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. |

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. . |

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.. |

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. . |

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.. |

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. . |

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. . |

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. . |

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.. |

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. . |

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. . |

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.. |

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.. |

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.. |

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.. |

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.. |

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. . |

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. . |

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.. |

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.. |

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.. |

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. . |

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. . |

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. . |

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 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. . |

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.. |

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. . |

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.. |

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.

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 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.. |

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. . |

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.. |

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.. |

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. . |

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. . |

In the near future, the pit limit of the mine will be reached and underground mine will then be developed through the open pit in the depth of 400 - 600 m from the surface. However, due to the challenges for underground mining such as poor geological conditions, extra thickness (20 - 30 m) of coal seams, and weak mechanical properties of coal seams and the surrounding rock, the success possibility of underground mining and an applicable underground mining method is being investigated at the present. The paper discusses the applicability of multi-slice bord-and-pillar method for the soft extra thick coal seams in the Mae Moh mine by means of numerical analyses using the 3D finite difference code “FLAC3D”.. |

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 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.. |

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.. |

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.. |

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. . |

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.. |

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. . |

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. . |

It is important to be implemented for management reclamation area in coal mining operation because as generally known that land is limited resource and improper land management led to decline in land productivity, so reclamation area needs to be well managed for sustainable land use. Purpose of this study is to evaluate land capability of reclamation area in Indonesia coal mining. The required data for land capability evaluation are climate properties, slope, erosion risk, soil properties, and natural hazard risk. This process consist of collecting land characteristic data include, soil properties, topographic properties, erosion risk, flood risk and landslide risk; soil laboratory analysis; data input and analysis using Land Classification and Land Use Planning (LCLP) software; land capability classification using LCLP. Land capability analysis in this study is carried out using LCLP software. LCLP is software to classify land and to generate new map according to the class of land capability.

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. . |

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. . |

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 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.

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.. |

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.. |

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. . |

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. . |

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.. |

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.. |

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. . |

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.

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. . |

(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. . |

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. . |

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.. |

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.. |

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.. |
