摘要
针对盐井二矿N运输巷裂隙瓦斯实际情况,创新采用"巷道底板混凝土浇底埋管抽放"及"巷道顶、帮贴壁封闭埋管抽放"方法治理巷道周边围岩裂隙瓦斯,对瓦斯压力小、涌出量小的裂隙瓦斯段治理效果明显。
Against with the actual situation of gas control,in the Yanjing 2 mine N road way,innovative use the way of pipe bottom drainaging in the pouring concrete roadway floor and the adherent closed roadway roof to control rock fissure gas,harnessing effect is obvious for small pressure and emission lot.
