Discrimination of seismicity distributed in different areas is essential for reliable seismic risk assessment mines. Although machine learning has been widely applied data processing, feasibility and reliability applying this technique to classify spatially clustered events underground mines are yet be investigated. In research, two groups with a minimum local magnitude (ML) −3 were observed an coal mine. They respectively located around dyke the longwall face. Additionally, types undesired...
Coal burst is a dynamic release of energy within the rock (or coal) mass leading to high velocity expulsion broken/failed material into mine openings. This phenomenon has been recognised as one most catastrophic failures associated with coal mining industry, which can often lead injuries and fatalities miners well significant production losses. paper aims examine mechanisms contributing occurrence, an emphasis on concept. In this study, numerical modelling study conducted evaluate roles...
This paper attempts to quantify the effect of backfilling on pillar strength in highwall mining using numerical modelling. Calibration against new empirical formula for was conducted obtain material parameters used With obtained coal parameters, three sets backfill properties were investigated. The results reveal that behavior pillars varies with type and amount as well width height ratio (w/h). In case cohesive backfill, generally 75% shows a significant increase peak strength, is more...
Designing reliable yielding support system to mitigate the effect of kinetic energy in burst-prone conditions mining and tunneling excavations is one challenges for geotechnical engineers. A combination elements can be used increase rock strength minimise displacement unstable mass. It important understand how works ensure stability underground excavations. Cable bolts have been commonly as an effective element reinforcement improve stability. are usually considered subjected static loads...
Safety is the highest priority in mining industry as underground particular poses high safety risks to its workers. In coal mines, bursts are one of most catastrophic hazards, which involves sudden and violent dynamic mass failure with rapid ejection broken material into mine workings. Despite decades research, contributing mechanisms still not completely understood. Hence, it remains challenging forecast quantify their likelihood occurrence. However, a range geological geotechnical factors...
This paper presents a new risk assessment methodology for coal mine excavated slopes. empirical-statistical slope stability (SSAM) is intended use by geotechnical engineers at both the design review and operational stages of mine’s life to categorise an slope. A likelihood failure determined using classification system slopes developed database 119 intact failed case studies sourced from open cut mines in Australia. Consequence based on height stand-off distance toe Results are presented...
Estimation of horizontal stress magnitudes from borehole breakouts has been an attractive topic in the petroleum and mining industries, although there are critical research gaps that remain unfilled. In this paper, numerical simulation is conducted on Gosford sandstone to investigate breakout its associated size effect, including temperature influence. The discrete element method (DEM) model shows angular span constant after initial formation, whereas depth propagates along minimum...
Strata failure is a principal hazard in open cut coal mining as it has the potential to cause multiple fatalities. Prior excavation of any slope, geotechnical assessment should review likely slope performance, including risk failure. Controls manage this an acceptable level accompany analysis. A survey 43 practising engineers indicated that kinematic and 2D limit equilibrium analyses were methods most commonly applied analyse excavated stability. While these are well established widely broad...
Geohazard prediction is one of the most important and challenging tasks in underground mining. It still remains difficult to improve accuracy make it compatible with ever-increasing data mining, especially when are sparsely allocated a large-scale mining environment. This study introduces an innovative multimodal fusion approach for geohazard address this challenge. By incorporating visual model as novel modality using interpolated rock mass rating cross-complementary factor, framework...
With the exploitation of deeper underground resources with harsh working conditions and significant geotechnical issues, it is challenging to quantify damage evaluation (especially anisotropic damage) stressed rock materials. The insufficient understanding inside may result in unexpected hazard potential engineering. However, most current acoustic emission (AE) data analysis limited isotropic stage AE-based characterisation has not been well integrated continuum mechanics. Therefore, by...
