大型矿山金属矿石高效开采技术研究

Research on high efficiency mining technology of metal ore in large mine

金属矿石作为我国紧缺且不可再生的宝贵资源,对其高效开采技术的研究是学者专家研究的重点课题。对大型矾山磷矿山的开采在总结前人经验和成果的基础之上,采用上向分层点条柱法,实现尾矿的循环利用,落实矿山绿色发展的最终目标。矾山磷矿西区还利用尾砂充填采空区,符合国家循环经济产业政策,对我国相似条件下金属矿石的开采工作具有良好的示范和指导意义。

Metal ore is a scarce and nonrenewable resource in China. The study of its high efficiency mining technology is a key subject for scholars and experts. On the basis of summing up the previous experience and achievements, the author uses the upward slicing method to realize the circular utilization of tailings and the ultimate goal of green development of mine. The use of tailings to fill the mined out area in the west of the mountain phosphate mine is in line with the national industrial policy of circular economy and has good demonstration and guiding significance for the exploitation of metal ore under similar conditions in china.
