he roof of the transportation roadway in No. 25 mining area of Changcun Mine was thick and weak. After mining, it was found that the two sides of the roadway were broken, and the surrounding rock was deformed seriously, which affected the normal use of the roadway. In order to solve the problem, the support system of the roadway was optimized by on-site monitoring, with analysis and research control technology, and the joint support scheme of anchor rod + anchor cable + anchor net was obtained, and the optimized scheme was numerically simulated and verified in the field. The results showed that with the optimized support scheme, the deformation of both sides and the top and bottom plates of the transportation roadway were controlled within the allowable range, which can meet the requirements of the lane ventilation and pedestrian, and ensure the normal and safe use of the transport roadway in the mining area.
