Abstract

The invention discloses a system for storing energy into a deep well and a construction method thereof. The system for storing energy into the deep well comprises an energy storage warehouse and an energy delivery system. The energy storage warehouse comprises a storage warehouse bottom member, a reinforced top plate, and one layer of storage warehouse middle member or multiple layers of storage warehouse middle members. The bottom of the storage warehouse middle member at the lowest layer is fixedly connected with the top of the storage warehouse bottom member. The reinforced top plate is fixedly connected to the top of the storage warehouse middle member at the topmost layer. The energy delivery system comprises an energy transport vehicle, an energy delivery pump, a first electric three-way valve and a second electric three-way valve. The construction method comprises the following steps that 1, the energy storage warehouse in the deep well is constructed; and 2, the energy storagewarehouse, the energy delivery system, a pressure stabilizing system and a controller are connected. According to the system for storing energy into the deep well and the construction method thereof,the realization is convenient, the energy storage warehouse has stable structure, high strength, good sealing performance and good impermeability; the energy storage security is high, rational utilization of mine goaf is realized, and the popularization and application value is high.

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...
