The efficiency of thermal insulation use in underground openings of cryolithic zone was evaluated. The measure of heat flow rate reduction from air to rocks was used as efficiency criterion. Influence of heat-insulating and heat-retaining coatings of the mine openings on rocks temperature conditions formation was analyzed. The conclusion on necessity of development of new combined coatings consisting of heat-insulating and heat-retaining layers was drawn.
