A system for regulating a non-energy-consuming complex environment in a mine based on compressed air energy storage, comprises: a compressed air energy storage power station; an air capturing and pressure stabilizing device; an air purifying device; a flow velocity and rate regulating device; and an intelligent decision-making and coordinated control system configured to: determine an air pressure within a valve seat according to a resistance change of a contact conductor; and compare the air pressure within the valve seat with a preset pressure value and control a driving mechanism to drive a valve core to move up and down according to a comparison result such that a pressure of air output by the air capturing and pressure stabilizing device is stabilized at the preset pressure value.
