Annotation:

Analytical method of calculation of the heat flow from the rock massif into mine tunnel located in it taking into account the formation of a cylindrical heat equalizing shell of rocks around the tunnel due to its thermal conductivity was worked out. By means of MathCAD 11 Enterprise the heat equalizing shell thermal resistance was determined and values of specific heat flux for the main types of rocks of deep horizons were calculated. Some ways and means of reduction of heat flow into the tunnel located in the massif are suggested.
