Mechanism and application of competitive fracture propagation in layered group fracturing of massive thick overburden strata

Abstract The massive thick overburden strata (MTOS) above the coal seam can result in high mining pressure in the stope, with significant manifestations of mine pressure, potentially triggering safety issues such as mine pressure bursts. In this paper, the fracture and migration characteristics of l...
