司家营铁矿残留矿体回收方案设计

Scheme Design for Recovering Residual Orebody in Sijiaying Iron Mine

结合唐钢司家营铁矿北区Ⅲ采场即将由露天开采转为地下开采的实际和N2-N4线间残留矿体的赋存状况,对残留矿体的回收方案进行了设计。

In light of the reality that No. 3 pit in north area of Sijiaying Iron Mine will proceed from open pit mining into underground mining and the occurrence of the residual orebody remaining between N2 and N4 lines, a scheme for recovering the residual orebody is designed.
