摘　　要：针对银山铅锌矿采场难以达到上采高度的问题,提出了采场内留点柱的支护方案。通过三维有限元数值模拟,得到了采空区与两帮应力、位移、安全率等分布的特征和规律及采场内留点柱的规格和位置。工程实践表明,该方案有效可行。In order to increase the stope height in Yinshan lead zinc mine, the support plan of remaining point pillars was proposed. 3D-FEM numerical simulation was carried out to analyze the characteristics and regularities of stress, displacement and security rate of mined-out areas and the sides. The size and position of point pillars in stope was obtained. Practice demonstrated that the support plan was effective.
