摘要: 采用阶段充填法大大提高回采率,并降低贫化率;利用选矿厂的尾砂进行充填,实现了资源的循环利用,降低了尾矿库压力,保护了矿区环境;采空区采用胶结充填后,消除了地表塌陷的危险,减少了地质灾害的发生。此采矿方法的推广使用,可以使吴庄铁矿取得良好的经济效益与社会效益,值得类似矿山借鉴。

关键词: 回采率, 贫化率, 胶结充填

Abstract: Adopt level filling method could improve mining rate greatly and reduce the dilution rate; filling by tailings from concentrator has realized resources recycling and reduced tailings reservoir pressure and protected mining area environment; dangerous of surface subsidence has eliminated and occurrence of geological hazard has reduced after cemented filling adopted at goaf. The extend and use of this mining method could get good economic and social benefits for Wuzhuang iron mine and worth learning by similar mine.

Key words: Mining rate, Dilution rate, Cemented filling
