下垄钨矿左拔矿区围岩破碎及矿脉密集采场回采技术研究

On the Stoping Technology in the Rock-broken and Vein-intensive Stope of Zuoba Mining Region

通过对采场结构参数与回采顺序调整、采场内点柱留设以及强化现场管理,对下垄钨矿左拔矿区围岩破碎及矿脉密集采场回采进行了现场试验研究,安全高效地回收了矿山资源,取得了较好的经济效益。

This paper studies the stoping technology in the rock-broken and vein-intensive stope of Zuoba mining region by adjusting structural parameters and mining sequence,leaving ore pillar points and improving stope management.The mining resources are recovered safely and efficiently with favorable economic benefits.
