特殊条件下综采工作面巷道布置及开采实践(作者:孔军峰)在井田边界、地质构造附近以及受老空、小窑等特殊条件下,采用风、机两巷平行、工作面不等长的布置方式,可以提高资源回收率,减少工作面搬家次数,提高单产水平,提高经济效益,确保矿井安全生产,并延长矿井服务年限。灵新煤矿自2008年以来,先后在四采区L4306综采工作面、L4406综采工作面,五采区051502综采工作面、目前正在回采的051602综采工作面使用此方式布置工作面,共安全回采原煤
Roadway - mechanized mining practice special conditions and arrangement (OF: Kongjun Feng) under special conditions minefield boundary, and by the geological structure near the goaf, small kiln, using air, two plane parallel to the roadway, unequal Face Arrangement, can improve the recovery rate of resources, reduce face moving times, improve yield levels, improve economic efficiency, ensure mine safety, and extend the service life of mine. Since 2008, Lingxin Coal Mine has set up working face in L4306 fully mechanized face, L4406 fully mechanized face and 0551502 fully mechanized face in No.4 mining area, A total of safe recovery of coal
