With the purpose of making full use of the energy of heat water flowed during m ining in underground metal mines,this paper analyzes underground heat water sour ces in eastern Shandong,points out the ways and methods to utilize geothermal wa ter in the mine,analyzes the advantage of heat pump in application to mines.The underground hot water source in some metal mine,Qingdao,is ntroduced also.Accord ing to the actualities of the mine,a heat pump exchange system was designed for the indoor heating of nearby buildings.Compare with heating with coal,the heat pump exchange system can reduce cost of indoor heating by 33%.
