湘潭锰矿红旗矿区自建成投产以来,井下生产用水一直由地表供给自来水,而井下涌出水却一律由水泵排至地表面流失.1981年9月开始,该矿区利用井下水作为井下生产用水,简单易行,供水可靠,经济效果显著.整个工程仅花资金1580元,而全年可利用井下水9.6万吨,节约排水电能6.6万度,全年共节约1.6万元,每吨矿石降低生产成本O.1元.鉴于矿区今后生产主要集中在-30米及
Since the completion of the Xiangtan Manganese Mine Hongqi Mine, the underground production water has been supplied by tap water from the surface, while the downhole water has been discharged from the pump to the ground surface. Since September 1981, the mine has used downhole water as downhole production water. Line, reliable water supply, economic effect is remarkable.The entire project only spent 1580 yuan, and the annual use of 96,000 tons of underground water, saving drainage power of 66,000 degrees, saving a total of 16,000 yuan a year, each ton of ore to reduce production costs O .1 yuan. In view of the mining area in the future mainly concentrated at -30 meters and production
