Micro-seismic (MS) technique can be used to appreciate rock failure process and severity of
damage by quantifying micro-earthquakes in terms of time, location, grade, and energy …

Coal in a natural geological mass is typically heterogeneous, potentially containing widely
distributed faults that affect gas migration and are closely associated with the occurrence of …

Mining activities carried out above an aquifer, especially in the hanging wall of normal faults,
generally involve the risk of water inrush. For a better understanding of the mechanism …

Water inrush in mines has always been a major technical problem restricting the safe
production of mines with abundant water. Seepage channels formed by fractures in rock …

Based on monitoring data and engineering geological conditions, the surface deformation
patterns caused by sublevel caving mining in the Dahongshan iron mine were analyzed. By …

Underground hydrogen energy storage (UHES) in lined rock caverns (LRCs) is a promising
solution for mitigating the instability of clean energy generation. However, the hydrogen …

Rock shear fracturing occurs frequently in engineering sites, such as underground tunnels
and rock slopes. One main factor is that the multiple presence of crack is complicated …

The stability of the roof in coal mining plays a crucial role in ensuring safe excavation. After
coal extraction, the roof experiences complex and unbalanced stress conditions, leading to …

Faults are common large geological structures in underground coal mining, and roadways
near faults are seriously damaged. When faults connect aquifer roofs, the roadway …

Fault-slip instability due to mining is a critical factor leading to coal bursts. To better
understand the impact of fault-slip release energy on a coal seam, a static and dynamic …
