High-temperature Heat Harm Control Method of Deep Mining

In view of the increasingly salient high temperature heat harm problem in deep mining process, the paper briefly analyzes the causes of high temperature, and puts forward a series of high temperature control methods accordingly. That is to take conventional nonlabor cooling and the artificial refrigeration cooling method as well as the use of new geothermal energy cooling and thermoelectric cooling technology. Through the practice research on heat harm governance of Dingji Coal Mine, the study achieves the expected goals of cooling except hot.
