黄金矿山缓倾斜薄至中厚矿体采矿方法研究

缓倾斜薄至中厚矿体在黄金矿山占有相当大的比例。这类矿体顶板稳定性差，普遍存在采矿生产能力低、损失贫化大、作业安全性差等问题。近年来此类矿体采矿方法研究与试验取得了较大进展，一些应用效果好的采矿方法分别在湘西金矿、秦岭金矿和鱼儿山金矿试验成功。本文介绍这些新的采矿方法，并分析其发展趋向。

RESEARCH ON MINING METHODS OF GENTLY INCLINED OREBODY WITH THIN-MEDIUM THICKNESS IN GOLDMINE

There are quite a lot of gently inclined orebodies with thin-medi-um thickness in gold mines. As roof stability is worse in these orebodies,the problems such as lower mining capacity, high ore loss and dilution,and worse safety etc. generally exist in the production of the mine. In pastyears,great progress have been made in the research and experiments on the mining methods for these orebodies.Some mining methods have been success-fully used in Xiangxi Gold Mine,Qinling Gold Mine and Yuershan Gold Mine.These successful new mining methods are introduced and the development trends of these methods are analysed.
