Taking the mining area of Tongkeng Mine transition from caving method to filling method as the research object, the thickness of vertical isolation pillar and horizontal isolation pillar calculated by Bieniawski pillar strength formula and K. B. Rupeneyt theory should be less than 9.0 m and 9.36 m, respectively. A three-dimensional fine ore body mining model was established based on FLAC3D, and the influence of the entire mining process on stope stability under different thicknesses of isolation pillar was analyzed. The numerical simulation results show that, when the thickness of vertical isolation pillar is 10 m, the vertical displacement of the stope is less than 0.1 m, the maximum principal stress is 50 MPa, the minimum principal stress is 7.5 MPa, and the safety factor is greater than 8.0.When the thickness of vertical isolation pillar is 8 m, the displacement around the stope increases obviously, the plastic failure zone scope increases obviously, and the safety factor decreases slightly. Therefore, it is recommended that the thickness of the vertical isolated pillar in the mining area of the caving method to the filling method in Tongkeng Mine is 10 m.

以铜坑矿由崩落法转充填法开采区域为研究对象，运用Bieniawski矿柱强度公式和K.B.鲁佩涅依特理论，计算得到垂直隔离矿柱和水平隔离矿柱厚度应分别不小于9.00 m和9.36 m。基于FLAC3D构建三维精细化矿体开采模型，分析在不同隔离矿柱厚度下回采全过程对采场稳定性的影响。数值模拟结果表明，垂直隔离矿柱厚度为10 m时，采场竖向位移小于0.1 m，最大主应力为50 MPa，最小主应力为7.5 MPa，安全系数大于8.0；垂直隔离矿柱厚度为8 m时，采场周边位移明显增加，塑性破坏区范围明显增大，安全系数略有下降。因此，推荐铜坑矿崩落法转充填法开采区域的垂直隔离矿柱厚度为10 m。
