Annotation:

Authors developed analytical method for calculating the heat flow from the rock massif into located in it tunnel which takes into account formation of a cylindrical heat equalizing shell of rocks around tunnel due to their thermal conductivity. Using MathCAD 11 Enterprise it is defined thermal resistance of heat equalizing shell for heat flux and it is calculated values of specific heat flux for the main types of rocks of deep horizons (sandstone, shale and limestone) during cooling of the rock mass by air flow moving in the tunnel with different speed. Authors proposed some ways and means of reducing heat flow incoming into the tunnel from the mine rock massif.
