我矿1984、1985年先后从美国埃姆科(ELMCO)国际采矿设备公司引进七台922型铲运机,又于1988年初从衡阳有色冶金机械厂购进同型号铲运机二台,用于采场出矿。另外还有江西拖拉机厂等生产的WJ—0.75及WJ—1小型铲运机八台用来掘进。 几年来,我矿应用铲运机获得了较高经济效益,使我矿提前超额完成生产任务,每年产量递增20万吨,到今年十月已安全出矿220万吨。
In 1984 and 1985, I successively imported Qitai 922 Scraper from ELMCO International Mining Equipment Company and purchased two sets of same-type scraper from Hengyang Nonferrous Metallurgical Machinery Factory in early 1988 for Stope mine. In addition there are production of Jiangxi Tractor Factory WJ-0.75 and WJ-1 small scraper eight for excavation. Over the past few years, I benefited from the higher economic benefits of using scraper for mine, which enabled mine to surpass the production task ahead of schedule. The output of mine increased by 200,000 tons per year and 2.2 million tons of ore was safely discharged by October this year.
