摘　　要：针对平里店矿区缓倾斜残留矿产资源的分布情况,建立FLAC3D模型,模拟分析研究原生矿柱与充填矿柱支撑下残留矿体围岩区域应力场分布规律、位移大小、垂直应力分布规律及其破坏场等。结果表明,得出采用充填矿柱置换原生矿柱的方案可行。According to the distribution of flat-grade residual mineral resources in Pinglidian,the distribution law of zone stress field,the displacement,the distribution law of vertical stress,damage field of the residual orebody surrounding rock under the support of juvenile pillar and back filling pillar are investigated by simulation with FLAC3D model.It is feasible from the numerical simulating analysis that juvenile pillar is replaced by back filling pillar.
