Method for building underground gas storage by backfilling strip mine pit and underground gas storage
The invention belongs to the technical field of compressed air energy storage, and provides a method for building an underground gas storage by backfilling an open pit and the underground gas storage.The method comprises the steps that deep digging is conducted at the bottom of the open pit till part of bed rock is excavated, and the underground gas storage is built on the bed rock; a vertical shaft is built, the bottom of the vertical shaft communicates with the underground gas storage, a plurality of gas conveying pipelines communicating with the interior of the underground gas storage are laid in the vertical shaft, and meanwhile artificial surrounding rock is built at the bottom of the mine pit to wrap the underground gas storage and the bottom of the vertical shaft; and the stripping waste slag close to the mine to be mined is backfilled into the open-air waste mine pit to form a backfilling area, the top of the vertical shaft is exposed out of the top of the backfilling area, and a plurality of gas pipelines in the vertical shaft are connected with a compressor and an expansion machine on the earth surface. The problems that a traditional gas storage chamber is high in construction cost and difficulty can be solved, and the problems of consumption, ground disaster prevention and treatment and ecological restoration of the adjacent stripping mining slag can be solved.
本发明属于压缩空气储能技术领域，提供一种露天矿坑回填建造地下储气库的方法及地下储气库,包括在露天废弃矿坑的底部深挖至挖除部分基岩，在基岩上建造地下储气库；建造竖井，使竖井的底部与地下储气库连通，在竖井中铺设若干与地下储气库内部连通的输气管道，同时在矿坑底部建造人工围岩，包裹地下储气库和竖井的底部；将临近待采矿山中的剥采弃渣回填至露天废弃矿坑中形成回填区，并使竖井的顶部从回填区的顶部露出，使竖井内的若干输气管道与地表的压缩机和膨胀机相连。本发明可以解决传统储气硐室施工成本大、难度高的问题，又可以解决临近剥采矿渣的消纳、地灾防治和生态修复问题。
