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

    推進工法は、都市部における管埋設工法の中で有効な方法として多用され,急速な進歩を遂げてきた。しかし,現在,都市部における下水道普及率は既に約72%を超えており,今後下水管渠埋設への推進工法の需要は低減することが予測され,また,他の生活関連整備に伴う管路構築においても同様に一段落の傾向にある。このような理由から,推進工法の新たな適用分野が模索されており,現在,山岳トンネルの長距離先受け工法や地下浅部のアンダーパス先受け工法への利用等が図られている。しかしながら、現在適用されている種々の先受け工法の施工では,仮設工であるために経済性や簡便な施工性のみが評価の基準となるため,施工に伴う周辺地山への影響についての基礎的な資料がこれまで十分には得られていなかった。そこで、本論文では、まずAGF工法と推進工法を用いたパイプルーフ工法の比較をはじめ、推進工法を用いたパイプルーフ工法の周辺地山の安定性に及ぼす影響等を明らかにするために,解析により種々検討した。その結果、先受け工法としては,パイプルーフ工法はAGF工法と同様な効果があることが分かった。また、パイプルーフ数あるいはパイプルーフ径の増大,トンネル内壁とパイプルーフ間の間隔が小さくなるほど,周辺地山の破壊領域の減少ならびに地表面沈下の抑制が可能であることが判明した。次に,推進工法を用いた先受け工法として適用した事例について報告し,地山の安定性に及ぼす種々の影響等について検討した。その結果,推進工法を用いたパイプルーフ工法により地表面沈下量を20mm程度に抑制できたことから,本施工方法はトンネル掘削のための補助工法として極めて有用性があることが判明した。

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

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

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

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

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

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

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

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

Therefore, visualization of the gasification zone of UCG is required for both improving gasification efficiency and developing UCG systems with low environmental impact. In this study, the large-scale model UCG experiments conducted on a laboratory scale (size: 625 mm × 650 mm × 2792 mm (H × W × L)) were carried out to discuss the visualization of the gasification reaction zone of coal in UCG by Acoustic Emission (AE) technique with uniaxial and triaxial acceleration transducers. As the results of temperature monitoring and AE source location analysis show, AE sources are located near the high-temperature zone (>1000 °C). In addition, the located AE sources move and expand with the movement and expansion of the high-temperature zone. AE measurement can be a useful technique for monitoring the progress of the UCG reaction zone. AE measurement with triaxial sensors is also useful to predict a high-temperature zone though the measurable range, which has to be considered.

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

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

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

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

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

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

    SPECTの撮像時間の推定におけるcounts-per-volume(CPV)法の利用可能性についてSPECTファントムを用いて検討した。1回の撮像で画質の4つの物理的指標を計測できる頭部用QIREファントム(QIRE-h)及び胴体用QIREファントム(QIRE-t)を開発した。QIRE-h及びQIRE-tファントムと人体脳及び胴部ファントムにおける標的臓器のCPV(TCPV)、シャープネス指数(SI)及びコントラストノイズ比(CNR)を計測した。また、SPECTの画質を視覚的に5段階評価した。4種類全てのファントムにおいて撮像時間とTCPVの間に相関が認められた。QIRE及び人体ファントムのSI及びCNRはほぼ同じで、TCPVも同等であった。視覚的スコア間の一致度は、QIRE-hと人体脳ファントムでは中程度で、QIRE-tと人体胴部ファントムでは高レベルであった。また、QIREファントムと人体ファントムのSPECTの画質の物理的指標と視覚的評価はほぼ一致した。

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

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

  • Amelioration of acidic soil using fly Ash for Mine Revegetation in Post-Mining Land

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

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

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

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

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

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

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

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

  • Numerical Study on the Applicability of the Pipe-Jacking Method for the Main Gate of an Underground Coal Mining in Weak Rock Mass

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

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

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

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