Abstract 11305 working face of Longan Mine in Taishan was taken as an example, the support optimization of roadway roof support by combining theoretical analysis, numerical simulation and field measurement was studied. By adjusting the arrangement of anchor bolt and anchor cable, analyzing the deformation of roadway and the stress of support during excavation, the optimized support scheme can effectively control the deformation of surrounding rock of roadway, thus achieve the expected support effect, improve the excavation speed, reduce the support cost, and provide technical guidance for the safe mining of roadway.
