铜录山矿是大冶有色金属公司的主要生产矿山,储量大,品位高,建设条件好。该矿一期工程于一九六五年开始建设,设计规模为日产矿石4000吨,其中露天开采和坑内开采各2000吨。自一九七○年投产以来,由于坑內开采长期达不到设计能力,采矿损失率又很大,因而出现两种意见:一种意见认为,全部改用大露天开采;另一种意见仍维持小露天加坑內联合开采。上述两种意见,经过多次现场会议 Copper recorded mine is Daye Nonferrous Metals Company’s main production mines, reserves, high grade, good construction conditions. The first phase of the mine was started construction in 1965 with a designed scale of 4,000 tons of ore per day, of which 2,000 tons are for open pit mining and pit mining.
