摘要
针对云锡公司采选分公司31-1#矿体的赋存条件及矿柱的特点,结合地压控制理论和回采工艺,优选了九个矿柱回采方案,采用三维有限元软件3D-σ对各矿柱回采方案进行了数值计算模拟研究。通过对各回采方案计算结果对比分析,优化了矿柱回采方案,对矿山实际工程具有重要的意义和参考价值。
Based on the habitat and characteristic of pillar and occurrence conditions of 31-1# ore body in Mining and Mineral Processing Plant of Yunnan Tin Company Ltd. , combined with ground control theory and mining technology, this paper proposes nine recovery mining jamb programs. By three-dimensional finite element software, numerical calculation studies of each program are carried out. Through the comparison and analysis of calculated resuits, the recovery mining jamb programs are optimized, which has an important meaning and reference value to the actual mine project.
