摘要
为探索麻姑山铜钼矿 -10 0m中段采场的残留富矿石回收 ,以试验采场研究上下均为采空区的矿体回采技术条件。采用矿体“楼板”处理法顺利地回采了试验采场 -98m～ -85m之间的高品位矿石 ,回采矿量 80 0 0t,贫化率为 10 % ,回收铜金属量2 48t ,为指导 -10 0m中段其他采场日后生产积累了宝贵经验。
In order to recover the residual rich ore in -100m level of Magu Mountain Cu Mo Mine, the mining technology for the ore body between over and below mined-out areas is investigated in the experimental stope The rich ore between -98m～-85m in the testing stope is successfully mined by the horizontal pillar ore recovery process 8000t ore is recovered, the ore dilution ratio is 10%, the copper recovered is up to 248t The other residual rich ore mining in -100m level can be directed by the achievements from the testing stope
