Abstract: There are a lot of low temperature heat energy in mine return air, and the temperature and humidity are basically constant. This part of heat energy has considerable use value. In this paper, a combination of heat pump technology and return heat recovery unit is proposed, and a small amount of electric energy is used to convert low level heat energy into high heat energy in the return air of the mine, thus replacing the traditional coal-fired boiler system, providing heat source for heating, wellhead antifreeze, and living hot water in the whole year, reducing the use of coal mine in mining area. Reducing the discharge of pollutants has realized the ecological concept of coal mining without coal in the real sense. The research project is located at 20km, west of Fengtai County, Anhui province. The administrative divisions belong to yuezhang Town, Fengtai county. This paper, based on the principle of the mine air source heat pump system, expounds the composition and characteristics of the system, and finally analyzes the economic and social benefits of the project. As the coal mine air source heat pump system uses the waste heat of the mine, the utilization cost of energy is far lower than that of other forms of energy supply. Therefore, the mine return air source heat pump system has good benefits in both social and economic sense. It is worth extensive research and research.Abstract: There are a lot of low temperature heat energy in mine return air, and the temperature and humidity are basically constant.
