STUDY ON THE SYSTEM OF UTILIZING AQUIFERS FOR COLD ENERGY STORAGE IN FATHERING DEEP MINE HEAT-HARM

Deep exploitation is the trend of development of resources in China.But the deeper of mining depth becomes,the more heat-harm is in deep mining,which results in miners working in a dangerous mine.Foreign large refrigerator units may reach the goal of cooling under mine,but they consume vast electric energy,so they can not be used widely in China.As a representative of new resources utilization technologies,geothermal energy utilization technology has many traits,such as economical operation cost,environment-protected and reliability,so the technology is developed and utilized.This paper takes Jiahe mine as an example,utilizing the technology of aquifers for cold energy storage,low enthalpy geothermal energy and wind energy are combined to store the cold energy in winter into shallow aquifers.Together with the HEMS,heat-harm is to be fathered.
