Against the background of growing global energy demand, the rate of extraction of various types of mineral resources is accelerating. However, with the increase of mining depth, the problem of high temperature and heat damage is gradually highlighted. The high temperature and heat damage not only affect the normal operation of various types of machinery and equipment, but also pose a serious threat to the safe production of the mine. The causes and effects of heat damage in mines were analyzed. At the same time, taking a hard rock uranium mine in the south of China as an example, through numerical simulation and other methods, the thermal and physical parameters of the surrounding rock of the mine, the geothermal field of the mine and the deep thermal environment were studied in depth, and on this basis, the existing problems of the mine were analysed, and the cooling technology was proposed.
