利用废弃矿洞建设抽水蓄能电站初探

Preliminary Study on Construction of Pumped Storage Power Station by Using Abandoned Mines

废弃矿洞建设抽水蓄能技术是一项对我国未来能源产业结构调整有着巨大促进意义的新兴技术。本文多方面阐述了利用废弃矿洞建设抽蓄电站的意义,在构建全地下和半地下两种矿洞抽蓄概念模型的基础上,梳理了国内外利用废弃矿洞建设抽蓄电站的研究、设计及实施进展,同时从地下空间利用、稳定支护及密闭、地下水源及防渗、地下工程布置4个方面初步分析了矿洞抽蓄电站建设的技术问题,为进一步研究和探讨利用废弃矿洞开展抽水蓄能应用技术提供有益指导。

Underground pumped hydro storage is a new emerging technology, which has great significance to promote adjustment of energy industrial structure in China in future. This paper explained the multi benefits of constructing underground pumped hydro storage in abandoned mine cavern. Based on the dedicated designed conceptual models of underground and semi underground pumped hydro storage, the research, design and implementation progress of underground pumped hydro storage at home and abroad are reviewed. The technical design scheme for the construction of typical underground pumped hydro storage is preliminarily analyzed from the aspect of underground space utilization, stable support and airtight, underground water source and seepage prevention as well as underground engineering layout. It provides useful guidance for further research and discussion on the application of pumped hydro storage technology in abandoned mines.
