观文煤矿煤与瓦斯共采中瓦斯抽采前期研究

 摘要： 以低透气性、强突出危险煤层群矿井—观文煤矿为研究对象，深入研究该矿的瓦斯抽采方案设计。抽采方案主要包括：保护层回采区域顺层钻孔预抽、邻近层卸压瓦斯、采空区瓦斯抽采、底板穿层钻孔预抽煤巷条带瓦斯、煤巷掘进工作面边掘边抽。

Pre-study of gas extracted of Guanwen colliery in simultaneous exploitation of coal and gas

Abstract Based on Guanwen coal mine, the multiple coal seams with low permeability and strong outburst dangerous, that gas extraction solution design thorough studied. Extraction scheme mainly includes: protective mining area gets bedding drilling pumping and adjacent layer discharging pressure gas, goaf gas extraction, backplane wear layer represents coal roadway channel drilling smoke gas and coal roadway heading face while digging and extracting.
