摘　　要：针对国内某大型铅锌矿露天转地下开采的开采技术条件,通过研究分析确定了地下开采方法为上向进路充填法。该文的研究对于露天转地下开采控制露天边坡稳定、促进矿产资源经济合理开发,提高资源回收率具有一定的指导作用。According to the study of technical conditions of a large-scale lead-zinc mine’s underground mining shifts from open-pit mining, the upward drift filling method is determined. The study in this paper offers reference for the open slope stability control of such mining shift, economical and rational exploitation of mineral resources and improvement of resource recovery.

关 键 词：露天转地下开采 上向进路充填法 资源回收率
