红透山铜矿自1975年开始使用机械化分层充填采矿法以来,采矿机械化水平有很大提高,但因管理工作没有跟上,使生产水平提高很慢。今年来全面加强了采场的质量管理,采取了一系列技术措施,获得很大成效。1～6月份,采场生产能力由原来日平均250吨左右,提高到400～600吨,经常稳定在430吨;采矿掌子面工效由原来的30吨,提高到50～94吨,经常稳定在56吨;贫化损 Hongtoushan Copper Mine Since mechanized stratified filling mining started in 1975, the level of mechanization of mining has been greatly improved. However, due to the lack of management, the production level has been slowed down. This year to fully strengthen the quality management of stope, adopted a series of technical measures, and achieved great success. From January to June, the stope production capacity increased from about 250 tons to about 400-600 tons per day, and was stable at 430 tons. Mining face efficiency increased from 50 tons to 30 tons, which was often stable At 56 tons; depleted
