Simulation Study on Energy Release and Weakening Effects of Pre-Fracturing in Hydraulic Fracturing of Thick Hard Roof

In this study, the thick, hard roof group of the 20103 working face in the Dahaize Coal Mine is used as the research object. UDEC discrete element simulations were conducted to examine fracture-induced energy release characteristics under unweakened conditions and single-layer hydraulic fracturing a...
