Abstract: Based on the characteristics of deep mine thermal pollution in China, the research status of deep mine thermal environmentin inrecent years has been summarized. The current research situation of underground thermal source was analyzed. It mainly in cluded the heat dissipation of surrounding rock, mechanical and electrical equipment, air compression, transportation, oxidation, water, the atmosphere and so on. For the thermal environment, the research of theoretical research, numerical calculation and indoor test has been reviewed. The evaluation of thermal environment was also analyzed.It gave several understandings on the research work which were presented in prospect of further study and discuss in the future: the coupling effect of multiple heat source should be considered in the theoretical predictions of air temperature; the large-scale similarity model test should be carried out and it can fit the actual to guide the production practice; the improvement of evaluation index of thermal environment.
