当前,在全国有色金属矿山中,从数量上说,有百分之八十五的矿山、从生产能力来说,有百分之六十五的矿山为地下开采矿山。大力革新有色金属地下采矿方法及其工艺设备,提高有色金属地下开采矿山的生产水平,对多快好省地发展有色金属工业,具有重要的现实意义。近年来,遵照毛主席“开发矿业”的伟大教导,各有色金属地下开采矿山,认真贯彻执行“采掘并举,掘进先行”的方针,大打矿山之仗,取得了新的成绩。与此同时,在矿山设
At present, among the non-ferrous metal mines in the country, in terms of quantity, 85% of mines have 65% of mines underground for their production capacity. Vigorously reforming non-ferrous metal underground mining methods and process equipment to improve the production level of non-ferrous metal underground mines is of great practical significance for the development of non-ferrous metal industry in a fast and economical manner. In recent years, following the great teachings of Chairman Mao’s “mining development”, each non-ferrous metal mine has been mined underground and conscientiously implemented the principle of “taking the lead in both mining and excavation” and struck a battle over the mine and achieved new successes. At the same time, set up in the mine
