Technology of determination on location of freezing wall water outlet for internal temperature measurement of freezer

In order to accurately judge a freezing wall water outlet location of the mine auxiliary shaft freezing project in Yili No. 1 Mine,atemperature measurement wa S conducted in internal longitudinal direction of the freezer in the main freezing hole. According to a heattransfer law of a single frozen soil pillar after the freezing hole stop ped its freezing operation,a mathematic calculation model of the freezingtemperature field distribution within the freezing soil pillar after an instant stop of the freezing was established. With the internal longitudi-nal temperature measured data of the freezer,the internal longitudinal temperature distribution law of each freezer in main freezing h ole ofthe mine auxiliary shaft in Xinjiang Yili No.1 Mine was obtained. The Maple mathematic calculation software was applied to the analysison the internal longitudinal te mperature data of each freezer in the main freezing hole of the mine auxiliary shaft in Yili No. 1 Mine. Thusthe location of the water outlet in the freezing wall was accuratel y judged and could provide a scientific basis to treat the water leakage ac-cident of the freezing wall.
