Abstract: Suncun Coal Mine is the earlier heat harm mine of our country. Heat harm problem has became a major disaster affecting mine production from the beginning of -600 m level. Based on the analysis of deep heat harm problem, it is revealed that Suncun Coal Mine is a heat conduction mine with geothermal heat and air compression as the main heat source. For the characteristics of Suncun Coal Mine, combined with the actual situation, heat harm control technology, which is named as local refrigeration cooling and cold temperature radiant cooling technology, is put forward. This heat harm control technology is worth to be applied and popularized in deep mining and related fields.
