Abstract In view of the phenomenon of shaft wall damage and water leakage at-190 m position of auxiliary shaft in Chensilou Mine, the main reason for the damage was that the underground mining activities caused the water level to drop and leaded to surface settlement, which caused the shaft settlement and the shaft wall to be damaged. Combined with the geological conditions of the shaft, the shaft wall was supported by the well ring of the shaft wall frame, and then the well ring was fixed vertically by the track. Finally, the treatment scheme of grouting reinforcement between the walls reduced the risk of water inrush and sand gushing in the shaft, and achieved the expected treatment effect of shaft wall reinforcement and water plugging.
