Abstract: According to the recent development of the third-generation geothermal engineering technology and the development of ground source heat pump technology, the connotation of SEST was proposed and the basic principle of SEST process system was presented. Combining with traditional shallow geothermal energy utilization technology and deep stratum energy storage technology, considering the features of coal mine, three energy storage models of energy storage system available in coal mine were given and also the mathematical analysis was done on model by adopted heat-transfer mechanism, the application in coal mine was analyzed through engineering application.

Key words: Stratum Energy Storage Technology, Energy Storage system, Energy Storage Model
