| 摘 要： | 针对门克庆煤矿工作面矿压显现强烈、煤层开采存在冲击灾害的问题,通过地质和开采影响因素对工作面进行冲击危险指数评价,并进行冲击危险性分区,由此制定了不同区域的冲击地压解危技术措施.通过微震、工作面超前支承压力和支架压力等方法进行监测,结果表明,在工作面回采期间围岩活动强度较低,能量释放平稳,解危效果良好.

| Abstract: | In view of the problems of strong mine pressure behavior and coal seam mining impact disaster in Menkeqing Coal Mine,the impact risk index of the working face is evaluated through the geological and mining influencing factors,and the impact risk zoning is carried out,so as to formulate the technical measures of rock burst in different areas.The results show that the surrounding rock activity intensity is low,the energy release is stable,and the effect of danger relief is good. |
