摘　　要：一八九○煤矿是焦煤集团生产骨干矿井之一,原设计采煤工作面平均倾斜长度为120m,工作面搬家次数较频繁,为提高矿井原煤产量,对采煤工作面巷道布置进行优化设计,采煤工作面倾斜长度由120m增加至250m。为此需要解决超长采煤工作面坚硬顶板处理技术,经过合理设计掘进一条深孔巷,在深孔巷、运输巷和回风巷采取布置长距离老顶孔和端头孔,实施深孔预裂爆破技术处理坚硬顶板。1890Urum qiisone ofthe backbone ofthe m ine coalproduction ofcoking coalgroup,the originaldesign ofa coalface with an average slope length of120 m eters,the working face m oving frequently tim es,in orderto im prove the outputofraw coal,to optim ize the design of roadway layoutcoalface,inclined length from 120 m eters to 250 m eters to increase coalface.This need to solve the long coalm ining face of hard roofprocessing technology,through the reasonable design ofa deep excavation roadway layout,take long distance and the roofhole head hole in deep roadway,roadway and return airlane,the im plem entation ofdeep hole presplitting blasting technology to dealwith hard roof.
