Abstract：In order to investigate the influence of in-situ stress distribution of the sliding structure to the coal and gas outburst,ANSYS software is simulated on the stress distribution of bedding section and cutting part of Baiping sliding structure. Simulation results show that the stress of sliding structure turning point section is the most concentrated,the underlying rock mass of sliding layer structure parts is larger and the stress variations of sliding structure bedding section is not obvious. Based on this,a coupling analysis is accomplished to the stress distribution of sliding structural belt and dynamic phenomenon on the 11171 face of Baiping mine and verifies the accuracy of the simulation results.
