摘要
通过对耿村煤矿12220综放工作面地质概况的分析,研究了冲击地压发生的影响因素,并划分了冲击地压的危险等级。结合该矿生产实际,利用钻屑法和电磁辐射法做为冲击地压监测预警的主要手段,采用煤层注水、爆破卸压、钻孔卸压等卸压解危措施来控制冲击地压的发生,形成了耿村煤矿冲击地压综合防治技术体系。
Based on the geology conditions of No12220 fully mechanized caving working face in Gengcun coal mine, the paper researched the factors of influencing rock burst and divided the danger level of rock burst. Combined with the actual condition of mine production, took the drilling cuttings method and electromagnetic radiation method as the main methods for the rock burst monitoring and early warning, used coal seam water injection, pressure relief by blasting and drilling as the measures to control the rock burst, and those formed the integrated control system of rock burst in Gengcun coal mine.
