substoping and caving

In accordance with the geological conditon of 5's mineral lode of Hao chang mine field of Guyi Iron ore, raising the sublevel caving design scheme and some suggestions in using the mining method.

针对故驿铁矿蒿场矿区5号矿体的地质特征,提出无底柱分段崩落采矿法的设计方案,并就该采矿方法的具体使用提出几点建议。

In addition, sublevel caving without sill pillar fit for the few orebody which are thick enough and multi layered.

分段空场法主要用于开采厚度大于5m的矿体,盘区房柱法主要用于开采厚度小于5m的矿体,对于有覆岩条件的局部多层位矿体采用无底柱分段崩落采矿法。
