Abstract: In view of the poor utilization of high exhaust air in the cooling system of independent mines, this paper proposes the integrated system including shallow ground heat storage, water source heat pump and mine cooling, which is mainly composed of shallow underground heat exchanger, mine cooling system, multi-functional and variable condition of water source heat pump units.The paper introduces the heat removal utilization of mine cooling system in non-heating season, the working process of buried pipe heat storage and the cooling tower auxiliary cooling, the working process of heating from ground source heat pump system operation. Based on the analysis, it is concluded that heat storage through cooling under the theoretical refrigeration cycle in non-heating season would save the energy of 26.5% compared with non-heat storage, which demonstrates the favorable economic advantages.
