急倾斜极薄矿脉采矿方法的选择及应用

Selection and Application of Mining Methods for Steeply and Extremely Thin Veins

为了减少矿山投资压力,通过综合对比,选择结构和工艺简单且生产技术和管理水平成熟的浅孔留矿法,对矿山+1 060~+375 m范围内急倾斜极薄矿体进行开采,缩短了建设工期,加快了资金的回收,为矿山取得了一定的经济效益。

In order to reduce the mine investment pressure, through comprehensive comparison, the shallow hole retention method with simple structure and technology and mature production technology and management level is selected to mine the sharply inclined extremely thin ore body within the range of +1 060~+375 m, which shortens the construction period, speeds up the recovery of investment funds, and achieves certain economic benefits for the mine.
