After a mine main shaft ,mine auxiliary shaft and mine ventilation shaft of Banji Mine con-structed ,water inrush and sand gushing accidents occurred in those shafts ,the mine shafts were dam-aged and a ground freezing method was applied to the water sealing and repair of the mine shafts. With a scientific and rational freezing monitoring and control plan set and a freezing monitoring and analysis enhanced ,data variation of the freezing temperature field could be timely understood ,development sta-tus of the freezing wall could be mastered and the number of the freezing refrigeration units in the freezing station could be timely adjusted. All above would not only meet the requirements of the freez-ing wall thickness and strength ,but could ensure the water drainage ,dredging and safety repair opera-tion of each mine shaft and avoid the mine shaft liner failed by the frozen-heave force. Therefore the operation cost of the equipment could be saved and good technical and economic benefits could be ob-tained.
