The invention discloses a system for storing energy in deep wells and a construction method thereof. The system includes an energy reserve and an energy transmission system; the energy reserve includes a bottom component of the reserve and a reinforced roof, and a middle part of the reserve. The component or the middle component of the multi-layer storage warehouse, the bottom of the middle storage component at the bottom is fixedly connected with the top of the bottom storage component, and the reinforced roof is fixedly connected with the top of the middle storage component at the top; the energy transmission system includes energy A transport vehicle, an energy transfer pump, and a first electric three-way valve and a second electric three-way valve; the method includes steps: 1. Construction of a deep underground energy reserve; systems and controllers. The invention is easy to implement, has a stable structure of the energy reserve, high strength, good sealing performance and good anti-seepage performance; the energy storage has high security, can rationally utilize the mine goaf, and has high popularization and application value.
Description
technical field [0001] The invention belongs to the technical field of mining and energy storage, and in particular relates to a system for storing energy in deep wells and a construction method thereof. Background technique [0002] In the mining process of metal mineral resources, the goaf has the characteristics of huge spatial scale, complex geological environment and serious safety hazards. At present, the treatment measures for gobs in metal mines mainly include: treatment of surrounding rock collapse, filling treatment, permanent pillar treatment, sealing treatment and other methods. Permanently leaving ore pillars is not conducive to efficient mining of resources, and the treatment of collapsed surrounding rocks is not conducive to the protection of the surface environment, and the closed treatment has great safety hazards. Filling is an effective technical method to achieve safe, clean and efficient mining of ore deposits, and it plays a dual role in protecting the...
