Problems solved by technology

But, in the prior art, there is also a lack of such an energy deep well underground storage and delivery system, and there is no method for building such an energy deep well underground storage and delivery system. When building such an energy deep well underground storage and delivery system, the energy storage How to lay out the storage in the deep well, how to design the energy transmission system, and how to connect multiple energy storages are all technical problems to be solved

Abstract

The invention discloses an energy deep-well downhole storage and transport system and a building method thereof. The energy deep-well downhole storage and transport system comprises an energy storagereservoir group, an energy transport system body, a pressure stabilizing system and a controller. The energy storage reservoir group comprises a plurality of energy storage reservoir sets. Each energystorage reservoir set comprises a plurality of energy storage reservoirs. The upper portions of every two adjacent energy storage reservoirs in each energy storage reservoir set are connected throughan upper communicating pipeline, and the lower portions of every two adjacent energy storage reservoirs in each energy storage reservoir set are connected through a lower communicating pipeline. Every three adjacent energy storage reservoirs in each energy storage reservoir set are arranged in an equilateral triangle shape. Each energy storage reservoir comprises a storage reservoir main body, and an energy transport pipeline assembly is arranged at the position, under a transport roadway, of the storage reservoir main body of each energy storage reservoir. The building method comprises the steps that 1, the energy storage reservoir group under a deep well is built; and 2, the energy storage reservoirs, the energy transport system body, the pressure stabilizing system and the controller are connected. According to the energy deep-well downhole storage and transport system and the building method thereof, the stability of the energy storage reservoir group is good, and the energy storage reservoirs are stable in structure, high in strength, good in sealing performance and good in anti-seepage performance; and reasonable utilization of a mine goaf can be achieved.

Description

technical field [0001] The invention belongs to the technical field of mining and energy storage, and in particular relates to an energy deep well underground storage and delivery system 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...
