摘要
福建某多金属矿床因多年民采形成了大量空区,开采条件复杂。基于矿床开采现状,创新性地将全尾砂上向分层充填开采技术应用于残矿回采。应用结果表明,矿块生产能力达到80t/d,采矿成本180元/t,贫化率7%,并实现了全尾砂井下充填,社会、环境效益显著。
According to the current situation of mining and structural features of underground goals in a polymetallic mine of Fujian China, cut-and-fill stoping mining method with total tailing was applied. The engineering application results show that the production capacity reaches 80 t/d with a dilution rate of 7% and mining costs of 180 yuan/t, and that total tailing was filled in underground goals. The society and environmental benefits are remarkable.
