摘　　要：为开展废弃矿井地下空间物理储能方式对比优选,在总结分析废弃矿井抽水蓄能、重力储能和压缩空气储能原理及发展现状的基础上,采用层次分析法选取6个一级指标(资源条件、技术方案、经济效益、环境影响、安全保障及能耗水平)、19个二级指标以及3种储能方案,建立了废弃矿井地下空间物理储能方式评价指标体系。以山西白家庄煤矿为例,基于专家打分法分析了各指标及方案层权重,获得一二级指标中的主控因素及影响程度,并基于此分析对比3种物理储能方式的优劣。结果表明,在一级指标中,安全保障权重占比最高,环境影响次之,之后依次是资源条件、经济效益、能耗水平和技术方案;在二级指标中,权重最高的3个指标分别是技术保障、自然生态、资金投入;在3种方案中,重力储能最具优势,其次是抽水蓄能,最后是压缩空气储能。研究结果可为废弃矿井地下空间物理储能方式的选择提供参考。In order to carry out the comparison and optimization of physical energy storage methods in underground space of abandoned mines,on the basis of summarizing and analyzing the principles and development status of pumped storage,gravity energy storage and compressed air energy storage in abandoned mines,the analytic hierarchy process was used to select 6 first-level indicators,19 second-level indicators and 3 energy storage schemes,and the evaluation index system of physical energy storage methods in underground space of abandoned mines was established.Taking Baijiazhuang Coal Mine in Shanxi Province as an example,based on the expert scoring method,the weights of each index and scheme layer are analyzed,and the main control factors and influence degree of the primary and secondary indicators in the evaluation system are obtained.Based on this analysis,the advantages and disadvantages of three physical energy storage methods are compared.The results show that among the first-level indicators,the weight of safety and security is the highest,followed by environmental impact,an then resource conditions,economic benefits,energy consumption level,and finally technical solutions.Among the secondary indicators,the three indicators with the highest weight are technical support,natural ecology and capital investment;among the three schemes,gravity energy storage has the most advantages,followed by pumped storage,and finally compressed air energy storage.The research results can provide reference for the selection of physical energy storage methods in underground space of abandoned mines.
