摘要
狮子山铜矿大团山ＸＩ＃２矿体系深部厚大矿体，采用分段空场法开采。在实践中，针对原设计的采矿方法存在的一些不足，对采场拉槽、采场底部结构，回采爆破等进行了一些改进，使采切工程量、大块率大大降低，而采场日出矿能力得到了较大的提高。
Datuanshan XI # 2 orebody at shizishan copper mine is a deep large size orebody,mined by the sub level open stoping method.According to some disadvantages of the mining method designed originally in the practical operation,some improvements of stope slotting,stope bottom structure and production blasting have been made to decrease the quantity of development and opening work and the ratio of large fragments,so that the daily ore removal of stope is increased greatly.
