废弃矿井改建抽水蓄能电站现状与展望

Present situation and prospect of reconstruction of abandoned mine into pumped storage power station

由于煤炭资源枯竭、资源整合以及淘汰落后产能等因素,大量的煤矿濒临关闭。为了合理地利用好煤矿开采遗留下来的可供利用地下空间,解决废弃煤矿带来的资源浪费问题,通过介绍国内外废弃煤矿地下空间改建抽水蓄能电站的现状,阐述废弃矿井地下空间改建抽水蓄能电站的基本原理与工程技术。并以此为基础,提出该技术未来需要解决的3个科学问题,首先应解决地下空间岩体稳定性影响问题,其次应关注输水系统稳定支护及密闭问题,最后应处理人员和大型设备高效与安全运输问题,为未来废弃煤矿地下空间改建抽水蓄能电站设计优化工程提供参考。

Due to factors such as the exhaustion of coal resources,the integration of resources and the elimination of outdated production capacity,a large number of coal mines in China have been closed or are on the verge of closing.In order to make good use of the available underground space left over from coal mining and solve the problem of resource waste caused by abandoned coal mines.We introduce the research status of pumped-storage power station reconstruction in the underground space of abandoned coal mines at home and abroad,expound the basic principle and engineering technology of the reconstruction of pumped-storage power station in the underground space of abandoned mines,and propose the future requirement for this technology to solve the three scientific issues:firstly,we should solve the problem of the impact of rock mass stability in underground space;secondly,we should pay attention to the stable support and sealing of the water delivery system;and finally,we should deal with the efficient and safe transportation of personnel and large equipment in order to provide a reference for the design and optimization of the reconstruction of pumped-storage power stations in the underground space of abandoned coal mines.
