Abstract: With the site investigation and theoretical calculation,the available heat sources and features of the industrial square in Wutongzhuang Mine were analyz ed and the evaluation on the stability of the available heat sources was conducted.The study showed that available heat sources of Wutongzhuang Mine mainly include the mine drainage water, Ordovician limestone water,mine ventilation,water drainage from bathroom and cooling water of air compressor.Among those,the available heat of the mine ventilation would be the largest and the most stable.The Ordovician limestone water and mine drainage water would be the second,but the heat supply quan tity both would not be stable. The heat supply from water drainage from bathroom and cooling water of air compressor would be quite stable,but the heat value was smal l.According to the features of the high heat loading in the mine,a multi heat sources combination plan was proposed to provide a low rank heat value to the heat pump s ystem in order to meet the heat supply requirements of the industrial square.
