浅孔溜矿回收间柱顶柱底柱回收方案

Recovery scheme of bottom column of column top column in recovery of shallow hole ore slips

在对有色金属矿山进行开采过程中,面对具有稳固的矿岩以及矿石无结块或天然急倾斜、薄及中厚以下的矿床,通常通过浅孔溜矿法进行开采作业,然而在具体实施阶段,存在非常明显的矿柱回收问题,造成非常大的损失,因此,备受采矿界的关注。文章以吉林海沟金矿为背景,对浅孔溜矿回收间柱顶柱底柱回收方案予以分析与探讨,旨在为矿柱回收问题提供参考。

In the process of mining non-ferrous metal mines, in the face of ore deposits with solid ore and rock, ore without lump or natural steep, thin and medium thickness, mining operation is usually carried out through shallow hole mining method. However, in the concrete implementation stage, there is a very obvious problem of recovery of pillar, causing very large loss. Therefore, it has attracted much attention from the mining industry. Taking the Jilin Hai Gou Gold Mine as the background, the paper analyzes and discusses the recovery scheme of the bottom column of the column top column in the shallow hole ore recovery, which is designed to provide reference for the recovery of the pillar.
