Abstract: For the problems of serious deformation and failure of the roadway under the influence of multiple mining activites in the close distance coal seams in Cuijiazhai Coal Mine in Hebei Province, we analyzed the reasonable position of the close distance mining roadways under the influence of mining by the theoretical analysis and the numerical simulation. According to the actual site conditions of E12503 working face of Cuijiazhai Coal Mine, we determined the combined support technology of anchor-net-rope, and determined that the relative horizontal distance between the mining roadway and the upper coal seam residual pillar should be greater than 25 m, and the width of the roadway pillar in the working face should be 20 m by the numerical simulation. It can be seen that the optimized design scheme has better application effect from the mine pressure observation, the maximum displacement value of the left side of the E12503 roadway 1^# station is 22 mm and the maximum displacement of the right side of the roadway is 8 mm and the maximum displacement of the roof is 5 mm after the influence of the multiple mining activites.
