摘　　要：急倾斜煤层开采,冲击地压动力灾害严重,通过煤样测定与地质因素分析,得出王家山煤矿冲击地压的发生原因是煤体物理性质、埋深、顶底板岩性与地质构造综合作用的结果。基于冲击地压开采范围的应力集中现象,结合监测预警、定向解危及高强度支护控制,提出了矿井冲击地压的防治技术,可为类似矿井的安全生产提供了借鉴。Dynamic disaster of rock burst is serious in steep fully - mechanized caving coal alyzing measure of coal sample and geology factors, it shows that physical property of coal, seam, through an- burial depth, roof and floor lithology and geologic structure are the seasons of rock burst in Wangjiashan Coal Mine. Based on the stress concentration phenomenon of rock burst in mining range, combining measuring and pre -alarming, ori- entation danger solution with high strength support control, the control technique of rock burst is put forward, and it provides reference for the safety production of other mines.
