In this article, by theoretical analysis, field-surveying research and numerical simulation analysis of heat-and-humidity environment of working face, we obtain the formation mechanism and distribution rule of the heat dissipation on high temperature mines' working face: the temperature field along track roadway to double track haulage roadway is linearly increased along the air flow. The thermal curve has three turning points, which is basically linearly increased. The wall rock and coal bed radiation, exothermic reaction and electromechanical device radiation are the main reasons of heat dissipation, which should be the key factor of controlling the heat hazard. The research method employed in this article possesses a very good practical value.
