ABSTRACT
The heat pump technology utilization for the geothermal heat waste heat recovery from mining water and ventilation air is one of the most promising solutions to the problem of coal and iron mines heat supply. The heat pump technology distinguishes its high energy efficiency and ecological friendliness but requires essential investments for its realization. Because of that the decision as for a heat pump unit assembling must be made on the bases of economic criteria (Samusia 2013).
