Model device for simulating operation of waste mine compressed air energy storage system

The invention discloses a model device for simulating operation of an abandoned mine compressed air energy storage system. A gas storage chamber structure comprises a glass fiber reinforced plastic sealing layer, a sliding layer, a prefabricated segment concrete lining layer and a surrounding rock layer, the two ends, in the length direction, of the gas storage chamber are each provided with a sealing coaming, and a stress loading system, a confining pressure loading monitoring system, a stress-strain monitoring system, a displacement monitoring system, a temperature and humidity monitoring system, an in-hole imaging system and an external air compressor are arranged; real-time acquisition and analysis of multiple parameters such as pressure borne by the model, generated strain, displacement, temperature and humidity are achieved respectively, and meanwhile energy storage and energy release are achieved through two dynamic processes of energy storage and energy release under the working conditions of differen
