摘要
铜山口铜矿在采切工程、充填系统不断优化分段空场嗣后充填法,先后应用-160 m中段6个采场,采切比降低了170m^(3)/万t;综合贫化率、损失率分别降低了2.23%、2.42%,采场生产能力提高了80.5 t/d,坑采车间直接成本降低了44.2元/t,优化后取得了明显好的效果,值得推广。
The sublevel stoping with post filling method has been continuously improved in the operation of Tongshankou Copper Mine,both in mining and backfilling.The method was applied consecutively in 6 stopes at Level-160 m,with operation indicators markedly improved:ratio of cutting/preliminary development and mining tonnage reduced by 17 m^(3)/kt,overall dilution and loss rates reduced by2.23%and 2.42%,stope production capacity improved by 80.5 t/d,direct cost of stope operation reduced by 44.2 yuan/t.The optimization thus serves as a good reference for the promotion of the mining method.
