Numerical Simulation Research on Unloading and Fracturing Characteristics of Immediate Roof Rock in Underground Coal Mining
Underground coal mining can induce deformation and failure of overlying strata and ground surface, which seriously endangers the safety of human life and property. During mining, the immediate roof rock successively experiences initial caving (fixed support on four sides) and periodic caving (fixed support on three sid...
