Study on instability mechanisms and control of coal pillar spalling and coal crumbs leakage during working face crossing faults
Abstract The stability of coal pillars in fault areas is crucial for ensuring the safe passage of working faces. Based on field observations, frequent coal pillar spalling and substantial tectonic coal crumbs leakage, as well as tilting of hydraulic supports, are observed when working faces transiti...
