Embodiment Construction
[0128] Such as figure 1 As shown, the energy transmission and storage method for storing energy in deep wells of the present invention comprises the following steps:
[0129] Step 1. In the process of filling the goaf of the deep well, the energy storage group is constructed in the goaf of the deep well;
[0130] In this example, combined with Figure 2 ~ Figure 6 , the energy storage group described in step 1 includes a plurality of energy storage groups 48, each energy storage group 48 includes a plurality of energy storages 26, and two adjacent energy storages in each energy storage group 48 The upper part of 26 is connected by upper communication pipeline 43, the lower part of two adjacent energy storage warehouses 26 in each energy storage warehouse group 48 is connected by lower communication pipeline 44, and the adjacent three energy storage warehouses in each energy storage warehouse group 48 26 is arranged in an equilateral triangle. The energy storage 26 includes a...

The invention discloses an energy transportation and storage method for storing energy in a deep well underground. The energy transportation and storage method comprises the following steps that 1, anenergy storage cavern group is built in a deep well goaf; 2, an energy transportation system is built on the ground and is connected with the energy storage cavern group; 3, a pressure stabilizationsystem is built on the ground and is connected with the energy storage cavern group; 4, a controller is built on the ground and is connected with energy storage cavern group, the energy transportationsystem and the pressure stabilization system; 5, the energy transportation system delivers energy to the energy storage cavern group for storage under the control action of the controller, and in theprocess of energy transportation and storage, the pressure stabilization system performs balancing control over the internal pressure of the energy storage cavern group under the control action of the controller; and 6, the energy transportation system can output energy from the energy storage cavern group to the ground under the control action of the controller. The energy transportation and storage method has high energy storage safety, can realize reasonable utilization of a mine goaf, and provides a new idea for energy storage cavern exploration.
Description
technical field [0001] The invention belongs to the technical field of mining and energy storage, and in particular relates to an energy transmission and storage method for storing energy in deep wells. 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 the mined-out areas of metal mines mainly include: treatment of surrounding rock collapse, filling treatment, treatment of permanently leaving ore pillars, and closed treatment. Permanently leaving ore pillars is not conducive to the efficient mining of resources, and the treatment of caving surrounding rocks is not conducive to the protection of the surface environment, and 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 ...
