Underground energy storage and energy utilization method for abandoned mine

Abstract

The invention relates to the technical field of mine utilization, and particularly relates to an underground energy storage and energy utilization method for an abandoned mine. The method comprises the following steps that S1, the current situation of the abandoned mine is researched, and planning is made; S2, a ground flood control ditch arrangement and water diversion scheme is designed; S3, an underground water storage roadway arrangement and maintenance reinforcement scheme is designed; S4, the ground flood control ditch arrangement and water diversion scheme is compared with the underground water storage roadway arrangement and maintenance reinforcement scheme; S5, a mine water extraction and heat utilization scheme is determined; and S6, a summer water taking and winter heating utilization scheme of the mine is completed. According to the method, energy resources in the abandoned mine are fully utilized, resource waste can be reduced, the development and utilization efficiency of the energy resources of the mine without energy production is improved, meanwhile, a strategic path for transformation, escape and sustainable development can be provided for abandoned mine enterprises, and then transformation and development of resource-depleted cities are promoted. In addition, the method has a promoting effect on improving the coal mine safety level of China, guaranteeing national energy safety and promoting sustainable and healthy development of economy.

Description

technical field [0001] The invention relates to the technical field of mine utilization, in particular to an underground energy storage and energy utilization method of an abandoned mine. Background technique [0002] my country is one of the largest mining countries in the world, with abundant mineral resources, especially coal reserves and output, ranking third and first in the world respectively. At present, coal is still the main energy source in my country. According to statistics, coal accounts for about three-quarters of domestic primary energy production and consumption. It is expected that in the next few decades, the status of coal as my country's primary energy source will not change. In the development process of coal mines and metallurgical mines, a large number of underground goafs have been formed. Only the coal mines form hundreds of millions of cubic meters of space every year, and many of the huge underground spaces are filled with a large amount of coal ...

AI Technical Summary

Problems solved by technology

[0006] (3) The accumulation of discarded minerals seriously damages land resources;

[0007] (4), Abandoned mines produce harmful gases, pollute the environment and cause safety hazards

[0008] 2. Abandoned mines and coal mine floods have caused extremely heavy casualties and economic losses to the country and the people

[0010] (1) Insufficient transformation, development and utilization of surface buildings (structures) and facilities in abandoned mine industrial sites, and failure to integrate with regional environment and urban functions;

[0011] (2) The underground space and mining facilities of abandoned mines have not been fully developed and utilized, there are potential safety hazards, and relevant technologies are lacking;

[0012] (3) Before the closure of the abandoned mine, the coal mining subsidence area, gangue field, railway, highway and other mining abandoned land have not been fully treated with the mining progress, and lack of integrity and integration, and there is still a phenomenon of reverse succession in the ecosystem;

[0013] (4) The water environment of the closed mine has changed, there are hidden dangers of pollution, and the water resources have not been fully utilized;

[0014] (5) Abandoned mines generally do not have a geological and ecological environment monitoring system, and there is a lack of basis and standards for supervision and management
