| 摘 要： | 在煤矿地质环境、动力和诱发因子综合分析的基础上，认为煤矿构造矿震机理是：在高值初始应力状态的煤矿区，地壳深部始终进行着应力传递的应变调整运动，地壳内部每一质点都处在均衡围压状态，由于煤系地层对外力敏感响应力和抵抗脆弱的特性，加之，于煤矿区采掘“卸载”作用使地壳内竖直应力降低，四周水平应力作用相对加强，驱使地壳深部构造不连续面积累应力释放，引起地震效应———构造矿震

| Abstract: | Basing on comprehensive analysis of the geologic setting,kineticing and inducing factors in coal mine,the author thinks that mechanism of the tectonic mine earthquake in coal district:that is the moving strain adjustment of stress passing through the deep crust of coal district.Because,there is high initial stress.Intercrustal particle located at the stateresistibility is brittle weakness and sensitivity response by exogentic action.In addition,the vertical stress is relief and horizontal stress is increment of storage in crust by the coal mining take form unloading action which drives the tectonic uncontinuous plane in crustal deep to releade the locally accumuated stress and produce induced seismicity tectonic mine earthqake. |
