摘　　要：我国是世界上用冻结法凿井穿过深厚表土层的国家之一,基于某煤矿实例,通过数值模拟分析研究利用冻结管作为地源热泵换热器地埋管的可行性,并提出以冻结管作为地源热泵换热器可实现深部地层冷量和热量的利用,实现冻结孔废物利用,开辟了煤矿热泵技术中一种新的取热途径。China is one of the countries of using freezing method to sink through thickest topsoil in the word. Based on a coal mine in- stance, the feasibility of using freezing tube as ground source heat pump heat exchanger is analyzed by the numerical simulation tech- niques. Research results show that it can achieve cold and heat utilization of deep strata, and also achieve the waste utilization of freez- ing hole, which opens up a new heating way of the heat pump technology in coal mine.
