Abstract

After coal mining, rock movement, fracture and stress redistribution of roof and floor surrounding rock are caused and mining-induced fracture field is formed. The fractured zone formed in overlying strata is an important channel and space for gas discharge and storage. The efficient gas drainage can be achieved by placing the drainage borehole in the rich area of fracture development. According to the mining engineering conditions of the 6135 working face of Qidong coal mine, the whole process of overlying strata separation, bending, subsidence, cracking and even upwelling is reappeared by using the method of similar materials simulation and computer numerical simulation.
