摘要
根据大红山铜矿实际情况,采用有限元数值软件对3种矿柱回采方案进行了数值模拟,以寻求最佳回采方案。结果表明,在留有矿柱支持顶板的情况下,安全系数相对较高,考虑回收率等因素,采用方案三进行回采是比较合理的。为该矿安全高效回采矿柱资源提供技术支持。
According to the actual situation of Dahongshan Copper Mine, the FEM software is used to simulate three kinds of pillar mining plans in order to find the best stoping method. The results show that the third pillar mining plan is reasonable by considering higher safety factor and high recovery rate of pillar in the case of leaving pillar to support the roof. The simulation provides technical support to the safe and effective mining of the pillar.
