摘要
针对北辛窑煤业井下综采作业时采空区分布范围广、存在大量积水,给煤矿井下的综采作业安全带来严重隐患的现状,采用高密度电法对井下采空区的积水情况进行勘探,综合运用采空区地面抽水及煤矿井下采空区泄水孔疏水的防水技术,实现了对采空区积水的有效治理。
In view of the situation that the goaf is widely distributed and there is a large amount of water in the fully mechanized mining operation in Beixinyao Coal Industry,which brings serious hidden trouble to the safety of fully mechanized mining operation in coal mine,the high density electric method is used to explore the water accumulation in the goaf.The effective treatment of water in goaf is realized by using the waterproofing technology of surface pumping in goaf and drainage hole in goaf in coal mine.
