冬瓜山铜矿二步骤采场回采方案的研究

冬瓜山铜矿经过五年的不断开采,目前52线～54线、54线～56线盘区的一步骤采场,大部分已经回采并充填结束。为了保持矿山生产的衔接和均衡性,现在开始进入二步骤采场回采阶段。本文结合冬瓜山的开采技术条件和二步骤采场回采条件及采准工程布置和凿岩、爆破等方面对二步骤采场回采方案进行了研究,收到了良好的技术经济和安全效果。

Study on Extracting Scheme of Two Step Stope in Dongguashan Copper Mine

After five years of continuous mining,the panel stope between exploration line 52 and 54,54 and 56 has largely been filling at present in Dongguashan copper mine.In order to maintain convergence and proportionality production of the mine,now the two step stope will been mined.In this paper,combined with mining technical conditions of Dongguashan copper mine,two step stope mining conditions,the engineering layout and drilling,blasting,and so on,the scheme of two step stoping is researched.This has received t...
