摘　　要：红透山铜锌矿经过多年的开采,目前矿山面临着边、远、窄等恶劣的开采作业环境。窄脉采矿场贫化指标一直居高不下,一度高于30%,甚至达到40%。给选矿厂的选别工序带来很多困难,同时也影响了有用金属的回收率。本文论述了针对红透山铜锌矿窄脉开采中贫化指标的超标,在确保采矿效率、作业安全的同时,采取有效措施,降低贫化率指标,并取得一定效果。After so many years of mining,Hongtoushan Copper Zinc Mine now is confronted with the bad mining environment of far,narrow and difficut to reach.Narrow vein stope depletion index has been very high,once more than 30%,and even reach to 40%.It brings a lot of difficulties to seletive process of dressing plant,at the same time also affectes recovery of useful metal.According to reseaching the problem of exceed standard of depletion index in narrow vein mining,and ensuring mining efficiency and operation safety,some effective measures were taken to reduce the dilution rate index,certain effects were obtained.
