摘要
铜绿山铜铁矿－２４５ｍ中段Ⅲ号矿体５线南矿段原设计采用ＶＣＲ法开采，后根据该矿段的开采技术条件和现场的实际情况，改用上向盘区进路充填采矿法开采，可比原设计的采矿方法降低贫损指标，提高生产能力，减少工程量，节省基建投资，其优越性是十分明显的。
ccording to the original design,VCR stoping was used to mine line 5 south section of No.3 orebody at -245m level in Tonglushan CopperIron Mine.However,in order to adapt the mining conditions of this ore section and the site circumstances,the original design has been changed with using upward panel access fill stoping,which can lower the targets of ore dilution and loss,increase the production capacity,reduce the quantity of mining works,save the cost of preproduction construction,with a very remarkable advantage.
