The mining space of large mining height coal face is large, the range of movement and caving of rock strata is large and the stability of supports at coal face is low and damage rate of supports is high, which significantly affects the safe and effic

In extra-thick coal seams, mining operations can lead to large-scale disturbances, complex overburden structures, and frequent and strong strata behavior in the stope, which are serious threats to mine safety. This study analyzed the overburden struc

The key to safely and efficiently mining steeply inclined coal seams under water-filled strata is to size barrier pillars appropriately and to control the structural integrity of the roof. We propose a method for goaf filling and grouting of steeply
