The article deals with the suction method of ventilation of the mine. Fresh air in the mine is supplied by air supply shaft (or shafts), and part of the air in the cold season, warm air heating installation in and through the hot-air channel flows into the shaft. The results of the process of mixing hot and cold air streams in the air-supply shaft, as well as air traffic on the trunks, taking into account the temperature and velocity, which are made on the mathematical model developed in the software package Solidworks flow simulation. The temperature in the hot-air heating air channel must be adjusted depending on the outdoor temperature. In the article the option of air heating installation of air heating, in which the air temperature in the air heater is channel 9 °С at ambient temperature of –20 °С. Considered air mixing process and the depth of the barrel depending on the reinforcement (channel width is less than the barrel diameter). It is also considered an option at the hot-air channel width equal to the diameter of the barrel, which characterizes the process airflow temperature changes in the depth of the trunk. The third option of using air heating installation, discussed in the article suggests the location of air heating installation in walls pithead. It is shown that heating of the air passing through heat exchangers installed on the perimeter of a building, provides necessary temperature of the air in the shaft.
