大厂铜坑矿低品位矿产资源开发利用思路

Development and Utilization Ideas for Ore Resources in Low Grade in Copper Ore

铜坑矿针对不同的矿体地质特征,采用不同的勘探和开采方式。根据锡多金属低品位矿体特点,采用坑探为主,探采结合的方法减少成本,提高回采率;针对锌多金属低品位矿体特点,采用以钻代坑,从一个主中段突破,减少探矿工程,采用集约机械化开采,加强综合回收研究,增加伴生矿产价值,对节约资源、延长矿山年限具有积极的作用。

Focusing on different ore's geologic characteristics,the copper ore uses different exploration and mining methods.Since the ore characteristics are that the tin content is high but the ore body's grade is low,usually pit prospecting is adopted.The method combining prospecting and mining can reduce cost and improve the rate of recovery.For the ore characteristics that the zinc content is large but metal is in low grade,it uses drilling to replace pit prospecting to make a breakthrough in main middle segment to reduce prospecting.Concentrated mechanization is used for mining to strengthen comprehensive recovery study.Associated mineral values is added.And it has positive functions to save resource and extend mine's age limit.
