摘　　要：谦比希铜矿东南矿体属于缓倾斜薄至中厚矿体,其1号矿体0线以北矿区矿体埋深已近千米,给安全高效开采带来了较大的难度。本文根据东南矿体北采区3^#盘区的开采技术条件,提出了预护顶进路分段空场嗣后充填法、进路分段空场嗣后充填法、进路阶段空场嗣后充填法三种布置形式,经过技术经济详细对比,结合谦比希铜矿开发的当地环境,从采场顶板管理和采场出矿安全性考虑,优先选择预护顶进路分段空场嗣后充填采矿法。The southeast orebody of Chambishi copper mine is a slight inclined and medium thick orebody,the depth of the 0-line north of No.1 orebody is nearly one kilometer,so it is difficult to realize safe and efficient mining.According to the conditions of No.3 area in the north of southeast mine,this paper will put forward three mining methods,including sublevel open stoping with pre-protected roof and backfilling,sublevel approach-open sstoping with backfilling,open stoping with backfilling,etc,after compared with detailed technical and economy,considered the local environment of Chambishi copper mine,and conbined with the roof management of the stope and the safety of stope mining,finally,sublevel open stoping in pre-protected roof and backfilling will be preferred.
