| 摘 要： | 结合矿山的实际情况,借鉴国内其它相似矿山的矿柱回收经验,对白山泉铁矿一中段的矿柱进行回收利用,并根据现场情况对采空区进行处理,保证下阶段矿房回采的安全性。矿柱回收采用分段凿岩间柱一次性爆破顶柱和间柱的方案,采空区处理采用下向平行深孔崩落顶柱充填采空区的方法,实践证明,矿柱回收方案是合理的,经济效益和空区处理效果良好,可为国内类似矿山提供参考。

| Abstract: | Combined with the actual situation of mine and the other similar mine residual recovery experience, the recovery technology and mine-out area processing were proposed of Baishanquan mine to guarantee the next ore mining security. The Recovery technology of ore residual was sublevel drilling rib pillar and one-time blasting crown pillar and rib pillar. The parallel deep drill blasting crown pillar was used to fill the mined area. The practice results showed that the ore residual recovery technology and the mined area processing were reasonable. The reference of ore residual recovery technology and the mined area processing were provided to similar mines. |
