摘　　要：结合关岭山煤业有限公司3#煤层复采工作面的工程地质情况,提出对旧采区进行残煤复采的同时回收部分断层煤柱的方案,通过数值模拟合理确定回采巷道在断层和采空区之间的位置,并给出巷道的支护方案。Based on the engineering geological condition of the secondary coal mining face of 3# coal seam in Guanlingshan coal industry Co., Ltd., the scheme of recovering part of the fault coal pillar in the old mining area for residual coal mining at the same time is put forward. The numerical simulation is used to determine the location of the mining roadway between fault and mined area, and gives the roadway support program.
