摘要
确定合理的矿柱尺寸直接关系到矿井的安全和高效生产,通过数值模拟分析软件UDEC4.0对矿层的开采方法进行优化分析,在采场围岩稳定的条件下,确定矿房宽6 m与矿柱宽6 m的方案为最优方案,采出率比现场实际方案提高12.9%。
The reasonable size of pillars bears to mine security and highly effective production. CanTing on the optimized analysis through numerical simulation analysis software UDEC4.0 to the method of exploitation, under the surrounding rocks stable condition, the chamber extends 6m and pillars extends 6m is the optimal project and the mining rate is enhanced 12.9% compared to practical plan.
