Technical challenges have always been part of underground mining activities, however,
some of these challenges grow in complexity as mining occurs in deeper and deeper …

The presence of geological faults is a significant contributing factor to coal burst in
underground mining. In this study, a large-scale discontinuum model was established based …

The investigation on dynamic shear fracture behaviour of rocks subjected to the simulated
geo-stress is of great importance for deep rock engineering. Four groups of dynamic mode II …

Near‐fault severe seismic activity is frequently observed when excavating deep
underground during various engineering projects. The present study elaborates a method to …

To investigate the mechanism of fault slips in coal mines, a biaxial shear experiment was
carried out under unloading condition based on the fault F16 in Yima city, China. Two rock …

Deep, highly stressed hard rock underground mines tend to experience elevated elastic
strain energy which can dissipate around excavations causing rock fragment ejections and …

To elucidate the mechanism of seismic activity taking place away from extracted stopes in
underground mines, this study focuses on the influence of a fracture network on the intensity …

Floor water inrush has always been an important problem affecting coal mine safety. The
water inrush from the deep coal seam floor is the final manifestation of the water inrush …

Stress redistribution can disturb existing faults, leading to fault shear slip. Investigating the
abnormal phenomena during the fault transition from steady to instability stages is crucial for …

Creep characteristics of rock mass are related not only to the confining pressure but also to
the degree of internal fracture damage. Revealing the creep characteristics of rock mass …
