Abstract：During a freezing construction period of the mine main shaft in Dingjialiang Mine ,the water level in the hydrogeological hole was varied abnormally and could not directly reflect the time of the freezing wall connection. According to the problem ,based on the analysis on the data of the measured temperatures ,an analysis was conducted on the water level ,pressure ,water flow quantity variation and other conditions of the hydrogeological hole ,the time of the freezing wall connection was deter‐mined. Then with the observation on the longitudinal temperature of the freezer ,the freezing wall con‐nection could be verified to provide scientific basis to the safety excavation and lining of the mine shaf t.
