永煤集团城郊煤矿年产原煤5 Mt,矿井采用立井2水平上、下山开拓方式。随着生产规模的扩大,采深加大,矿井采掘接替加快,需要做大量的岩石巷道。为提高岩巷单进水平,确保采掘正常接替,该矿于2007年组建了一条由全液压掘进钻车、侧卸式装岩机和电机车组成的岩巷机械化作业线。1 工程概况城郊煤矿-495 m水平西翼轨道运输巷承担着西翼采区的主要运输和通风作用,同时也连接着-800 m水平的运输大巷,承担一定的-800 m水平的运输,该巷道能否快速施工完成直接决定着该矿的正常采掘
Coal in Yongjiao Group Coal Mine produces an annual output of 5 Mt of raw coal, vertical shaft 2 mine shaft, down the mountain to develop ways. With the expansion of production scale, deep mining, mine mining to take over, need to do a lot of rock roadway. In order to improve the single-entry level of rock roadway and ensure the normal succession of excavation, the mine set up a rock mechanized mechanization line consisting of fully hydraulic drilling rig, side-mounted rock loader and electric locomotive in 2007. 1 Project Overview Chengjiao Coal Mine -495 m horizontal West wing rail transport lane bear the main West West mining area and the role of ventilation, but also connected to the -800 m level of the transport lane, to assume a certain level of -800 m of transport, The rapid construction of the roadway can be completed directly determine the normal mining of the mine
