摘要
本文针对潞安矿区余吾煤业分别施工的顶板富水区专项探放水孔和瓦斯富集区的瓦斯抽采钻孔,提出了将顶板定向探放水钻孔改造为瓦斯抽放孔的"一孔多用"的方案和施工方法,并就效果和推广应用的可行性进行了分析。
For drilling the water drainage holes in the roof rich water area the gas drainage holes in the rich gas area of Yuwu Coal Mine in Lu＇an Coal Mine Group, the ＂one hole muhi-purpose＂ scheme and construction method for transforming the top roof directional exploration water drilling into gas drainage holes are proposed, and the feasibility and application feasibility are analyzed.
