中国废弃矿山地下抽水蓄能电站技术要点与可行性分析

Technical key points and feasibility analysis of underground pumped storage power station in built abandoned mines in China

为应对全球气候变化、化解资源环境危机,中国需推进能源结构调整与优化,逐步提高可再生能源开发利用比例,加快解决可再生能源存储的瓶颈问题。中国废弃矿山数量巨大,利用废弃矿山遗留下来的大量地下空间建造抽水蓄能电站为中国可再生能源存储提供了新的思路。基于德国利用废弃金属矿山和煤矿地下空间建造地下抽水蓄能电站的实例,从岩石力学、矿山规划、机械构置、能源系统规划、法律、环境影响以及经济性等方面深入探讨了中国利用废弃矿山建造地下抽水蓄能电站的相关评价原则与技术要点,并进一步提出了中国废弃矿山地下抽水蓄能电站研究的基本方向和主要内容。

In order to cope with the global climate change and the resource and environmental crisis,the energy structure in China should be adjusted and optimized,to gradually increase the proportion of the renewable energy development and utilization,and to solve the bottleneck problem of the renewable energy storage.In China,there are a large number of abandoned mines,which provide a large underground space to construct underground pumped storage power stations for the renewable energy storage.Based on two examples in Germany,this paper reviews related issues from the viewpoints of the rock mechanics,the mining planning,the mechanical settings,the energy system planning,the legal,environmental impacts,the economic applicability,the evaluation principles and other technical key points.The basic directions and the main contents of the related researches are discussed.
