Abstract: The mine exhaust wind contains abundant low temperature thermal energy. Under the non-extreme weather conditions, the low temperature residual heat in the mine exhaust wind can be used to meet the thermal demand of the well head.In order to use the heat in mine exhaust air to solve the problem of heat used in wellhead anti-freezing, a separation type power heat pipe waste heat recovery and utilization system is proposed. This paper introduces the form of the system and analyzes the system configuration by taking a specific project of a coal mine in taiyuan as an example.The initial investment and operating cost of the system are low and the environmental and economic benefits are good.It provides a new method to solve the problem of mine anti-freezing.
