Application of domestic shuttle car in tunneling of long distance large section coal roadway
Ma Jin-gong
Abstract：According to the technical characteristics of domestic SC Series shuttle car,and the engineering background of Wangjialing Coal Mine,three kinds of shuttle car collocation process were put forward for double lane parallel operation under the condition of large section and long distance(300m)coal roadway,advantages and disadvantages of different schemes were analyzed,the footage estimate related time factor and the formula of Tcirculating =max(Tcuting,Tsupportting) +Tmachine + Tassisted was proposed according to the engineering practice,the actual running time of shuttle car in excavation process and the causes were analyzed,and the revamping of roll cable device was introduced.The practice proved that the prediction formula of footage parameters is reliable,the cable guide wheel group transformation reduces the cable fault,improves the shuttle car boot time,enhances domestic shuttle car stability,thus improves the overall efficiency,practical results has important reference and guidance significance for introduction of the shuttle car in similar mining conditions.
