摘　　要：全球废弃矿井数量已超过100万座,到2030年,我国废弃矿井数量将达到1.5万座,如何合理利用废弃矿井地下空间资源成为当今能源环保领域热点议题。可利用废弃矿井的地下巷道、硐室或采空区等废弃空间建设抽水蓄能电站地下水库。但其狭长密闭、纵横交贯的地下空间水域完全不同于常规抽水蓄能电站地表水库的开敞空间水域,抽水蓄能电站建成运行时其地下水库的水力特性将完全不同于地表水库的水力特性。为此,本文分析了抽水蓄能电站地下水库的模式及特点;总结了国内外抽水蓄能电站地下水库建设进展;提出了抽水蓄能电站地下水库的关键水力学问题。研究成果可为科学利用废弃矿井建设抽水蓄能电站地下水库提供指导。There are more than 1 million abandoned mines in the world,and the number of abandoned mines in China will reach 15,000 by 2030.How to rationally utilize the underground space resources of abandoned mines has become a hot topic in the field of energy and environmental protection.The underground reservoirs of pumped-storage hydropower can be constructed by using abandoned spaces such as tunnels,chambers,or mined-out areas.However,because of its narrow and closed underground spaces,it is completely different from the open spaces water area of the surface reservoirs of conventional pumped-storage hydropower.The hydraulic characteristics of the underground reservoirs are completely different from those of the surface reservoirs when the pumped-storage hydropower is built and operated.Therefore,this paper analyzes the mode and characteristics of the underground reservoirs of pumped-storage hydropower.The progress of underground reservoir construction of pumped-storage hydropower at home and abroad is summarized.The key hydraulic issues of the underground reservoirs of pumped-storage hydropower are put forward.The research results will provide guidance for the scientific use of abandoned mines to build underground reservoirs of pumped-storage hydropower.
