Research and application analysis of mine waste heat utilization technology
The heating of the air shaft site and buildings by the waste heat from mine ventilation air methane(VAM)and water inflow.Taking Shaanxi Shanmei Caojiatan Mining Industry Co.,Ltd.as an example,the heat demand,heating status,and residual heat of the mine were analyzed.A design scheme for waste heat utilization system was proposed by combining a direct cooling deep enthalpy heat extraction exhaust heat pump with mine water inflow waste heat utilization technology,and the operating effect,economic and environmental benefits of the system were analyzed in detail.The results indicated that the waste heat from mine VAM and water inflow could meet the heat demand of the mine and achieve significant economic and environmental benefits.
