1973年以来,云南有色矿山在平巷掘进机械化方面投入了大量人力、物力和财力,自制和购置了大量专用设备。伹由于设备实际应用于生产的很少,多年来设备数量虽然增加不少,但矿山机械化程度并未提高。在掘进各环节中都使用机械化设备的掘进队为数很少,其中,云锡马拉格掘进八队应用效果较好,它已形成了一条稳产作业线,由1978～ Since 1973, Yunnan Nonferrous Mines has invested a great deal of manpower, material and financial resources in the mechanization of roadway driving and has made and purchased a large amount of special equipment.伹 Due to the fact that the equipment is actually used in production, although the number of equipment has increased a lot over the years, the degree of mine mechanization has not increased. There are only a few excavation teams that use mechanized equipment in each step of the tunneling. Among them, the eight teams of the Yunxi-Mallag tunneling have good effect and have formed a stable production line,
