深井冲击地压综合防治技术的应用

Integrated prevention technology of pressure bump in deep mining

针对深部矿井在开采过程中遇到的一些冲击地压问题,通过微震监测技术、数值模拟分析等方法预报了可能存在的冲击威胁,依据强度弱化减冲理论,对危险区域针有对性地采取大直径钻孔卸压技术和煤体爆破卸压技术等解危措施,有效地解除了冲击地压危险,实现了安全生产,对于后期矿井进入千米开采阶段的防冲工作具有借鉴和指导意义。

In view of the problem of rock burst during the coal mining, the technique of microseismic monitoring and numerical simulation are used to forecast risk of rock burst. Based on the intensity weakening theory, large- diameter bored stress-relief techniques and coal blasting pressure relief techniques are used to eliminate the threat of rock burst effectively in danger zone, which ensures the safe production of coal mine, and provides reference and guide meaning of rock burst prevention for coal mining below 1000 meters.
