【摘要】 针对华亭煤矿进入深部开采冲击矿压日益凸显,严重危及矿井安全生产的现状,加大资金投入,加强技术研究,综合分析冲击矿压发生的原因,采取声发射、微震、电磁辐射、钻屑等综合监测手段,分区分级预测预报冲击矿压;采取顶板深孔爆破、煤体卸压爆破、煤层及顶板注水、钻孔卸压等综合防治手段,按照不同地点冲击矿压的危害程度,分级分区地开展矿压防治工作,达到冲击矿压综合防治的目的。更多还原

【Abstract】 Rock-burst has threatened safety mining of Huating Colliery with mining depth increasing.This paper comprehensively analyzed rock-burst cause and made prediction with different danger areas and grades by acoustic emission,micro-seismic,electromagnetic radiation and drilling method.Comprehensive prevention methods including deep-hole blasting for breaking roof,coal blasting for pressure relief,water injecting into coal and roof and drilling for pressure relief were applied according to different danger degrees of varied places to comprehensively preventing rock-burst.更多还原
