Abstract: Pointing to the problem that a period of the new auxiliary shaft wheel-dreven bypass in Tianzhuang coal mine of Linyi Mining Group deformed too largely under the double effect of the soft rock and fault, the deficiencies of the original “U Steel+bolt-mesh-coshot” supporting method was analyzed, and a scheme of using grouting reinforcement to governance this period of roadway and using anchor cable to strengthen support as the assistant was put forward. The results showed that using this method to repair the damaged section of bypass can make the broken rock pieces back into a whole, the strength and stability of surrounding rock were improved, water and air erosion of surrounding rocks was stopped, and that the safe use of bypass in its service period can be sure.
