In addition, a large amount of dust, gas and other pollutants are also generated during the underground mining process, posing a threat to the safety of workers and production safety. Therefore, it is very necessary to cool down the high-temperature underground coal mine environment.

[0003] At present, the measures for cooling the mine are mainly divided into non-artificial refrigeration and artificial refrigeration.
