目前,对于我国绝大多数矿井，轨道运输仍是井下大巷的主要运输手段，我国现有煤矿轨道近万千米，由于井下工作条件差、行车密度大、光线弱等原因，致使机车运输通过能力差且事Forthevastmajorityofourmine,railtransportisstillthemainmeansoftransportoftheundergroundroadway,ourexistingcoalminetracktenthousandkilometersundergroundworkingconditions,trafficdensity,weaklightandotherreasons,resultinginthemotorcycletransportthroughcapacitypoorandfrequentaccidents.矿井轨道运输的这种状况,将直接影响到煤炭的生产情况。
