冶金部于1981年4月13～15日在辽宁红透山铜矿召开了DC-2-6型底侧卸式矿车技术鉴定会。该矿车是由北京有色冶金设计研究总院和西华山钨矿,在端底卸式矿车的基础上,共同研制成功的。它适用于平巷运输,通过的最小巷道断面为2.2×2.4米。这种矿车1980年8月在红透山铜矿正式投入工业试验,截止1981年1月底,共运矿石35011吨。每台矿车平均运行1296趟,折算为1945吨一公里,已超过了部规定的试验运矿量指标。试验证明,该矿
The Ministry of Metallurgy held a technical appraisal meeting of DC-2-6 bottom side unloading tub at April 13-15, 1981 in Hongtoushan Copper Mine, Liaoning Province. The mine car by the Beijing Nonferrous Metallurgy Design and Research Institute and the West Huashan tungsten mine, in the end of the bottom of the unloading car, based on the successful development. It is suitable for road transport, the smallest roadway through 2.2 × 2.4 meters. This kind of mine car officially started its industrial test at the Hongtoushan copper mine in August 1980. By the end of January 1981, it had shipped 35,011 tons of ore. The average operation of each mine 1296 times, converted to 1,945 tons a kilometer, has exceeded the Ministry of the provisions of the amount of test transport indicators. Test proved that the mine
