摘　　要：不断优化巷道布置方式,降低巷道掘进率,是矿井开采设计过程中的一项非常重要任务。合理布置巷道,降低巷道掘进率,可降低吨煤成本,提高经济效益。龙湖煤矿的具体措施是:加大采区工作面的长度,采用倾斜长壁采煤方法,实施上下山联合开采,推广沿空留巷方法,采用机轨合一巷和机轨合一上(下)山的布置方法。Optimizing roadway arrangement way unceasingly,reducing the tunnel drivage ratio is an important task in the mine mining design process.Selecting the reasonable roadway arrangement method,reducing the roadway drivage ratio,may reduce the ton coal cost,raise the economic efficiency.The specific measures in Longhu Coal Mine are： enlarging the length of face in working area,using the inclined long wall coal-mining method,on the implementation united mining with up-downhill, promoting retaing roadways along goaf,using the machine-track-one roadway and the machine-track-one up-downhill arrangement way.
