摘　　要：为探讨滑动构造带地应力分布对煤与瓦斯突出的影响,采用ANSYS软件对白坪滑动构造带的顺层面和切层面应力分布进行数值模拟。结果表明,滑动构造转折端部位应力最为集中,滑动构造切层部位下伏岩体应力较大,滑动构造顺层部位应力变化幅度不明显。以分析白坪矿11171工作面滑动构造带的应力分布与动力现象为例,验证模拟结果的准确性。In order to investigate the influence of in-situ stress distribution of the sliding structure to the coaland gas outburst, ANSYS software is simulated on the stress distribution of bedding section and cutting part ofBaiping sliding structure. Simulation results show that the stress of sliding structure turning point section is themost concentrated, the underlying rock mass of sliding layer structure parts is larger and the stress variations ofsliding structure bedding section is not obvious. Based on this,a coupling analysis is accomplished to the stressdistribution of sliding structural belt and dynamic phenomenon on the 11171 face of Baiping mine and verifiesthe accuracy of the simulation results.
