During Jingchuan's second period of mining development engineering for trackless haulege ramp at 1150 level, poor geological conditions, roadway with large cross section area, pressing time schedule and other restrictive conditions make it the only choice to use track equipment for operation. Since there are no raise chutes for unloading when U-shaped mine trucks are used for haulege, a track mechanical production line for excavation is adopted, which is dominated by bucket rear-dump muckers, shuttle trams, shuttle transfer cars together with smooth blasting, metal nets shotcrete rockbolt support. Excavation of single face with large cross section in poor rock formations has been carried out for three months running, forming 50m roadway for each month, thus offering a new approach to increase excavation speed of drifting in Jingchuan.
