【摘要】 通过研究大红山铜矿生产矿量保有的划分、统计原则和合理的保有期限,对中厚缓倾斜矿床空场嗣后充填法地下开采提出新的生产矿量保有计算依据和方法,在保证矿山持续稳产的前提下,矿山采选能力达到设计能力的260.6%,为类似矿山持续、均衡、稳定生产和取得最佳经济效益提供参考。更多还原

【Abstract】 The studies on classification methods,statistical principals and rational remain periods of Dahongshan copper mine are introduced in this paper.The results show that new basis and methods to calculate productive ore reserves of inclined deep deposits sublevel open stoped with subsequent backfilling.In this way,sustainable and stable production can be ensured,and the practical capacity can be realized 260.6% as planned capacity,which provides reference for other similar mines.更多还原
