摘要
基于杜儿坪煤矿62515综采工作面概况,分析了工作面瓦斯来源,提出了一种本煤层钻孔预抽、倾向顶板钻孔抽采和大直径钻孔抽采的综合抽采技术,取得了非常好的效果,为该工作面的安全回采提供了保障。
Based on the general situation of the 62515 fully mechanized mining face in Duerping Coal Mine, this paper analyzed the gas source of the working face, and proposed a comprehensive pumping technology of pre-extraction of the coal seam, predraining of top hole and large diameter drilling extraction, which achieved very good results, providing guarantee for the safe recovery of the mining face.
