南京铅锌银矿全尾砂胶结充填试验与系统改造

Whole Tailings Cement Filling Test and System Transformation at 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、尾泥无法进入采场 ,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 ,实行了全尾砂的充填。在满足充填体强度等要求的情况下 ,解决了细粒尾砂的排放问题。

In view of the problem that due to the low filling density and low cement filling strength of the original filling system,the tailings could neither come into the stope nor be allowed to be discharged into the ground environment,whole tailings cement filling technology was researched and whole tailings filling realized.It has not only met the requirement of the strength of filling body,but also solved the discharge problem of fine tailings.
