Abstract

The invention discloses an underground gas storage and a site selection and transformation method for reconstructing the underground gas storage by using a waste mine hole, high-pressure gas is sealed and stored by fully utilizing good sealing performance, low permeability and underground water pressure of a natural stratum, and the construction cost of sealing measures of the underground gas storage can be greatly reduced; meanwhile, underground waste spaces such as the goaf of the waste mine cave and various waste caverns are utilized, and the utilization efficiency of the underground waste spaces is greatly improved; in addition, the abandoned mine cave roof determined according to the site selection step has the advantages of being good in deformation resistance, high in strength and the like, and therefore large-scale reinforcement treatment does not need to be conducted on an original abandoned goaf and a roadway of the original abandoned goaf, and the construction cost of project reconstruction is greatly reduced. The anti-seepage structure is simple, the engineering construction process is simple, the construction technical difficulty is small, and the construction technical level of reconstructing a large-scale underground gas storage by using the abandoned mine can be further improved.

Description

technical field [0001] The invention belongs to the field of underground gas storage, and in particular relates to a site selection and reconstruction method for reconstructing an underground gas storage by utilizing abandoned mines, and an underground gas storage. Background technique [0002] For the mining of various minerals buried deep underground, it is necessary to excavate a series of tunnels or chambers, and a large number of goafs will be left after the minerals are mined. For goafs with good roof rock mass, backfilling is generally not performed after mining; at the same time, the underground spaces such as prepared tunnels and open tunnels constructed for underground mining will also remain after the mining work is completed. [0003] The utilization methods of abandoned mine space are divided into two types: single development and utilization and multiple development and utilization. Single development and utilization is to transform the abandoned mine cave spa...
