Abstract: Maintaining a given thermal regime is the most important factor in creating comfortable working conditions for miners and safe operation of equipment at mining enterprises. Regulation of the thermal regime of modern mines requires a large amount of energy to heat the air. The article presents the results of comparative tests of thermal and hydraulic characteristics of three promising layouts of heating installations. Designs of water heaters of different types are presented. It is shown that a higher heat transfer coefficient for the layout of the heater of the new design can significantly reduce the metal consumption and dimensions of the heater installations. An obvious further step in the rational use of finned pipes in air heating devices is to optimize the layout of heaters and ensure the rational flow of heat carriers.
