分层充填采矿法在中厚以上矿体开采中的运用

Application of cut and fill mining method in mining medium thick ore body

平底结构浅孔留矿法适合对倾斜薄矿体进行,但是针对开采超过四米的矿体,使用此类方法存在着很高的贫化率,采场的生产力较小,机械化程度低,劳动强度大,而且运行安全方面偏低,因此,在后期开采工作中,其逐渐被盘区机械化分层充填采矿方法代替。基于此,本文就云南黄金集团红牛铜矿工程概况与地质开采条件,分析采矿方法的使用,提出机械化盘区上层水平的分层填充方法,仅供参考。

Flat bottom structure shallow hole shrinkage method is suitable for mining inclined thin ore body,but for mining ore body more than four meters,using this method has high dilution rate,small stope productivity,low degree of mechanization,high labor intensity,and low operation safety.Therefore,in the later mining work,it is gradually replaced by panel mechanized slicing and filling mining method For you.Based on this,this paper analyzes the use of mining methods according to the general situation and geological mining conditions of hongniu copper mine of Yunnan gold group,and puts forward the layered filling method at the upper level of mechanized panel,which is only for reference.
