| 摘 要： | 采用岩石破裂与失稳分析系统（RFPA），对不同构造应力条件下煤矿区地表环境损害特征进行数值试验，结果表明：处于伸展构造背景下的煤矿区，煤层覆岩受到拉张构造应力作用，在煤层开采过程中，覆岩运动、变形和对地表地质环境的损害相对比较强烈；而处于挤压构造应力作用下的煤矿区，覆岩运动、变形及其对地表地质环境的损害相对较弱，或表现滞后。

| Abstract: | The results from numerical tests of ground damage related to coal mining under different tectonic stress conditions with rock failure process analysis system show that in the coal mining area of tension tectonic setting,both the motion and deformation of surrounding rocks as well as the damage degree of ground geological environment are relatively more acute,whereas the motion and deformation of surrounding rocks and the damage degree of ground geological environment will decrease or lag behind in the coal mining area under the action of compressive tectonic stress. |
