With the site investigation and theoretical calculation, the available heat sources and features of the industrial square in Wutongzhuang Mine were analyzed 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 quantity 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 small. 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 system in order to meet the heat supply requirements of the industrial square.%通过现场调研及理论计算,分析了梧桐庄矿工业广场可利用的热源及特点,并对可用热源的稳定性进行了评价。研究表明：梧桐庄矿可用热源主要有矿井排水、奥灰水、矿井排风、洗浴排水、空气压缩机冷却水,其中矿井排风可利用热量最大、最稳定;其次为奥灰水、矿井排水,但两者供热量均不稳定;洗浴排水和空气压缩机冷却水供热量较稳定,但热量较小。根据该矿热负荷较大的特点,提出了多种热源联合为热泵系统提供低品位热量的方案,以满足了工业广场供热需求。
