Study on the linkage mechanism between key strata fracture in overburden and surface subsidence during caving mining in extra-thick coal seams
Abstract Caving mining in extra-thick coal seams induces large-scale overburden movement, leading to more intense fracture processes in key strata, more significant surface subsidence, and frequent dynamic disasters in mines. This study, using the N34-2 caving face of the 17th coal seam at Junde Min...
