摘　　要：文章通过对松散介质力学性质、放矿椭球体理论再认识总结出在具有压实状态下矿岩松散体流动规律,提出狮子山铜矿主矿体振机采场放矿工艺,放矿现场制度,达到增加采场放矿纯矿石回收量,降低采场贫化率、损失率指标。Based on mechanical properties of loose media and the theory of drawing ellipsoid, the flow pattern of loose ore and rocks under compaction state is investigated. The technique and roles for ore drawing are worked out and proved to be successful in increasing recovery of pure ore and reducing the dilution and loss of ore at the mining area.

关 键 词：间歇式 斜面推进 放矿椭球体 主矿体
