Through the engineering example, according to the data of the auxiliary shaft and return air shaft during the active freezing period of the freezing and refrigeration project in Dingjialiang Mine in Ningdong area, the two wells started at the same time, but the shallow hydrological hole of the return air shaft started to water later than the auxiliary shaft. The longitudinal temperature of the freezing device and the hydrological hole was detected in the return air shaft, and the temperature measurement data of the two wells were different was analyzed. The refrigeration data can provide an example reference for similar strata in the same area in the future.
