义兴寨金矿“零隐”号脉采矿工艺研究

Study on Mining Process of "Ling-ying" Range at Yixingzai Gold Mine

分析了义兴寨金矿“零隐”号脉开采地质条件和主要技术问题。该矿体使用传统的浅孔留矿法采矿工艺存在诸多缺陷,采用人工分层底柱下向分层采矿法技术可行、经济合理、安全性高。

The characteristics of the existence of ore body and main technological proposes in Lingying Mountain Range of Yixingzai Gold Mine were analyzed. Traditional mining process of shorthole shrinkage stoping in the ore bady has some problems.With useing the mining method of bottom-pillar downwards lamination, the better technological and security and economic profits were achieved.
