| Abstract: | In order to achieve the goal of high-efficiency gas extraction and ensure the safe production of working face，and make full and rational use of gas resources，aiming at 81112 working face of Pingshu Mine，using theoretical analysis，analogy simulation and CDEM numerical simulation，the movement of overburden strata and the distribution law of cracks in goaf are studied，the primary and periodic breakage distances of basic roof，the height and evolution form of overburden cracks are obtained，the three-dimensional position and scope of crack development ring are determined，and the high-level extraction roadway or high-level boreholes and horizontal orientation of surface are determined，the optimum location of boreholes can achieve the goal of high efficiency gas extraction. |
