Abstract Most of the ground buildings in the industrial square of coal mines are multi-storey buildings, usually not more than 20 m, but there will be 1 or 2 high-rise buildings ( more than 50 m ). In order to solve the heating problem of high-rise buildings, the fixed pressure should be increased, resulting in pressure overpressure of low-rise buildings. Moreover, the cylindrical coal bunker is often far from the computer room, and the cost of adding a single high-rise heating system is very high. In order to solve this problem, the application of direct connected pressurization and decompression circulation device in the heating system of multi-storey and high-rise joint buildings in coal mines was introduced, and the practice was carried out in Ciyaogou Coal Mine of Hequ County. The results show that these devices solve the problem of overpressure in high-rise heating system, save cost and prolong the working life of equipment.
