摘　　要：通过经验公式计算和三维有限元数值模拟,确定了云驾岭铁矿嗣后充填采矿中永久矿柱留设的合理参数,使其地表沉降在地表建筑物允许的范围内,既保护了地表建筑物不被破坏,又能最大限度的回采村庄下的矿产资源。An empirical formula and 3D finite element numerical simulation are used to determine rational parameters for permanent mineral pillar set for filling mining of Yunjialing Iron Mine so as to make sinking of the earth＇s surface in the allowable range of ground buildings. It can protect the earth＇s surface buildings and stope mineral resources under the villages as far as possible.

关 键 词：充填采矿法 永久矿柱 矿产资源
