REGULATION OF THERMAL REGIME OF COAL MINES IN CRYOLITHIC ZONES
Abstract
Results of research into the choice of rational parameters of thermal regime in coal mine workings of the permafrost zone which are minimizing energetic and economic expenses of creation of normative parameters of mine microclimate are presented. It is determined that there is an optimal temperature to which the air in the coal face should be heated. It is demonstrated that the most rational method of air heating is the one employing heating devices distributed along the length of the coal face. Basic criteria of choice of tempera-ture in the mine workings are justified.
