Study on the Failure Mechanism for Coal Roadway Stability in Jointed Rock Mass due to the Excavation Unloading Effect

Aiming at the large deformation instability problem caused by the excavation unloading of a coal roadway in deep-buried slowly inclined jointed rock mass, the geomechanical parameters and deformation failure characteristics of an engineering geomechanical model were investigated. The in-situ stress...
