Heating of atmospheric air in cold period and its cooling in heat period is offered in special ventilation channels due to the heat exchange with deads. Channels are placed in neutral layer, combining their horizontal axils with horizontal axile of neutral layer. Taking into account the cross-section, air consumption and timbering of channels, their length is calculated, taking into account the provision of the size of required heating (cooling) of mine supply air. Parameters of ventilation channels were calculated for conditions of potassium mine, placed in Volgograd Oblast (Russian Federation). These calculations have shown that in case of application of offered methodology of temperature control of underground excavations supply air, depression in ventilation channels is increased approximately by 10% from total mine. Increasing of length of ventilation channels makes possible to provide the normative temperatures of mine supply air with lesser and higher temperatures of atmospheric air. Ventilation channels, situated on the depth of neutral layer of Earth, make it possible to realize the heating of mine (shaft) supply air in cold period of year, and cooling in the warm period, without application of any installations and means, but due to rational use of laws of nature. In comparison with existing methods of heating and cooling of mine (shaft) supply air, the capital and exploitation costs are significantly lower.
