全尾砂胶结充填技术在杨山铁矿的应用

为最大限度的回收矿产资源,保证矿山安全生产,实现矿山绿色开采,本文针对杨山铁矿床地质及开采技术条件进行了简要分析,提出采空区采用嗣后全尾砂胶结充填。并说明矿山采用嗣后胶结充填的矿石回采率比不进行充填的矿石回采率高18%左右。

To recover the mineral resources maximum, ensure the safety of mining production and realize green mining, this article gives a brief analysis on Yang Shan mining’s ore deposits geology and mining conditions and proposes to take Cemented full tailing backfill in the goaf. And explain that the recovery rate of ore to take Cemented full tailing backfill is 18% higher than the one that didn’t fill.
