摘　　要：基于武钢金山店铁矿矿柱现状,运用弹塑性有限元理论对矿柱开采可行方案进行了仿真模拟,对不同方案矿柱开采过程中围岩和地表的稳定性进行了分析。在对矿柱开采覆岩移动及地表变形规律进行总结的基础上,对金山店矿柱采用不同方案开采地表破坏区域进行了圈定,确定了合理的矿柱开采方案。Based on the pillar status of Jinshandian iron mine in WISCO,the feasibility scheme of the pillar mining is simulated by using elastic-plastic finite element theory and the stability of the surrounding rock and surface among the mining process by different scheme is analyzed.Based on all summaries about the pillar mining strata movement and surface deformation law,the damaged area in the surface during Jinshandian pillar mining with different mining schemes is delineated.Then,the reasonable pillar mining scheme is determined.
