我国煤矿冲击矿压一般表现为煤爆。冲击矿压以煤层冲击最常见,也有顶板冲击和底板冲击,冲击类型多种多样。但是可以预防与防治的,目前冲击矿压的预测防治都是围绕冲击矿压发生的强度条件和能量条件进行的。通过对煤岩体的应力水平和分布状态以及能量积蓄和释放等变化进行监测,在时空上判断煤岩体破坏形式、规模和释放能量的大小,并以此来进行冲击矿压的预测防治。
China’s coal mine rock burst is generally expressed as coal burst. Rock burst to the impact of the most common coal seam, there are roof impact and floor impact, a variety of impact types. However, for the prevention and control, the current prevention and control of rock burst are all based on the intensity and energy conditions of rock burst occurrence. Through the monitoring of the stress level and distribution of coal and rock mass and the change of energy accumulation and release, the damage form, scale and energy release of coal and rock mass can be judged in time and space, and the rock burst can be predicted and prevented.
