Abstract

The utilization of abandoned mines to build compressed air energy storage (CAES) power stations can fully utilize land and space resources and reduce excavation costs. It possesses substantial economic and ecological advantages and has garnered widespread attention in recent years. Therefore, the construction of CAES for gas storage is introduced, the development prospects are systematically analyzed, the advantages and existing problems of CAES in abandoned mines are discussed, and then a novel pipe layout design for CAES technology in abandoned mines is proposed (using large-diameter seamless steel pipe as gas storage space, adding loose filling bodies into the gaps to hold pressure).Numerical simulations were conducted to analyze the surrounding rock stability and structural deformation under long-term creep loads for different types of gas storage. The results indicate that this scheme has the following advantages: ① it reduces the site selection requirements of the power station and increases the site selection range; ② it reduces the difficulty of constructing gas storage facilities; ③ it avoids the risk of gas leakage; and ④ it avoids the impact of corrosion on the gas storage facility, which increases its durability. This study provides novel ideas for the development of abandoned mine CAES technology and has the potential for large-scale promotion and application.

管布置式废弃矿井压缩空气储能技术的新概念及稳定性分析

利用废弃矿山建设压缩空气储能电站，可以充分利用土地和空间资源，降低开挖成本。它具有巨大的经济和生态优势，近年来受到广泛关注。为此，介绍了储气CAES的建设，系统分析了储气CAES的发展前景，讨论了废弃矿山CAES的优势和存在的问题，提出了一种新的废弃矿山CAES技术管道布置设计（采用大直径无缝钢管作为储气空间，在空隙中加入松散充填体保压）。通过数值模拟分析了不同类型储气库在长期蠕变荷载作用下的围岩稳定性和结构变形。结果表明：该方案具有以下优点：①降低了电站选址要求，增加了选址范围；②降低了储气设施的建设难度；③避免了燃气泄漏的危险；④避免了对储气设施的腐蚀影响，提高了储气设施的耐久性。本研究为废弃矿山CAES技术的发展提供了新的思路，具有大规模推广应用的潜力。
