南京铅锌银矿全尾砂胶结充填

Full Tailings Cemented Filling Technology in Nanjing Lead-zinc-silver Mine

针对南京铅锌银矿原有充填系统充填浓度低、胶结充填强度低、细粒级尾砂无法进入采场,且地表环境不允许尾砂排放的问题,开展了全尾砂胶结充填技术研究,实现了全尾砂充填。

In order for solving the problems of the low backfilling density, low cemented filling strength, of the original backfilling system, and the fine fraction tailings neither coming into the stope nor being allowed to be discharged into the ground environment in Nanjing Lead-zinc-silver Mine, the full tailings cemented filling technology is investigated and full tailings backfilling is realized.
