Practice of Reinforcement Support Technology for Driving Roadway Through Fault

The main underground inclined shaft in Wangmangou Coal Mine encountered collapse column when driving, and the surrounding rock instability, roof subsidence, fragmentation and spalling occurred in some areas. The combined support method of Bolt, mesh, cable and shotcrete is put forward, which can effectively control the deformation of the surrounding rock of roadway, avoid roof sinking and roof leakage, and make the working face pass through the subsided column safely and smoothly.
