摘要
从矿井特有的地质条件入手,对矿井开拓延深方式、开拓准备巷道层位选择、巷道布置及巷道密度确定、煤柱留设、巷道水治理、巷道支护参数确定、爆破效果的控制等方面进行分析,从而得出提高清水营煤矿软岩巷道支护效果的技术途径。
Based on the specific geological conditions of coal mine, the factors including the mine exploration and extension methods, the choice and preparation of roadway layers, the roadway layout and density determination, the coal pillar design, the roadway water control, the roadway support parameters determination and the blasting effect control are analyzed. Therefore, technique ways for im- proving the supporting effects of the soft rock roadway in Qingshuiying Coal Mine are obtained.
