摘要
为了减少巷道掘进工程量,降低巷道掘进率,论述了加大采区尺寸和增加工作面长度,倾斜长壁采煤法,上下山联合开采,沿空留巷,机轨和一和机轨合一上(下)山等具体的降低巷道掘进率的方法,这些先进的采煤技术的应用,增加采区服务年限,保证矿井生产采区的正常接续,同时可降低生产成本,提高企业的经济效益。
In order to reduce roadway digging amount, decrease roadway digging rate ,the article discusses the ways of decreasing the roadway digging rate that increase size of mining area and increase the length of working face, the method of inclined long-wall mining, up-pit and down-pit mining, retaining roadways along goaf, and so on. These advanced coal technology applications increase the mining area＇s service time limit and guarantee the continuous normal operation of production area and at the same time improve the economic efficiency of enterprises.
