Research on Thermal Energy Recycling Utilization in High Temperature Mines

This paper designs an integrated system of mine cooling and thermal energy utilization with high temperature mines as the object of the research. The system can not only run in the refrigeration condition to provide low temperature cold source for cooling in high temperature mines, but also run in the heating condition in winter to provide heat source for ground buildings by recovering the thermal energy in the mine. This integrates the technology of heat pumps and mine cooling, involving in both mine cooling and heat recovery utilization in the mine. One system meets the dual demand for both high temperature mine cooling and ground building heating, which realizes the great reduction of equipment investment and operating cost as well as the recycling of energy.
