| 摘 要： | 应用ANSYS有限元分析软件和相似材料模拟实验，分析在采动和断层影响下覆岩变形破坏和矿压分布规律。结果表明：在采动影响下断层“活化”，断层带及其影响范围内的岩体破碎，表现为周期断裂步距小，冒落带高，尤其是断层下盘，顶板稳定性差。通过断层后，顶板岩体中支撑力减小，比无断层存在的情况低。但断层时于上覆岩层导水裂隙带的高度和范围的影响不明显。

| Abstract: | The authors analyzed the laws of deformation and failure of overlaying strata and the distribution of mine pressures under the influence of faults and mining activities by applying the ANSYS finite element software and similar materials simulation test.The results indicated that the faults were "activated" by coal mining,and the rock-mass in fault zone and its influential range was broken,and the distance of periodic weighting decreased and the caving zone increased,particularly,the roof stability in the fo... |
