The construction of Pumped storage power station entails large investment, strict requirements on environment, society, economy and safety, thus its site selection is highly influenced by numerous factors.Abandoned mines have natural elevation difference and space resources, which could save cost and shorten construction period for project modification of abandoned mines into pumped storage power stations.Based on the threshold theory, this paper puts forward the preliminary screening model for the location of abandoned mine pumped storage power station, comprehensively evaluates and optimizes the selected mines by using the coupling model of expert opinion and triangular fuzzy TOPSIS decision-making, and puts forward the multi-stage decision-making process and method system for the location of optimal pumped storage power station in combination with the requirements of sustainable development and resource reuse.The results show that the key indicators of site selection decision are mine water volume, water head, the distance from power grid, underground space, earthquake frequency, underground surrounding rock support stability and local power consumption.The natural conditions of the mine itself play a decisive role in the transformation of the pumped storage power station.Amony the alternative, Shigejie Coal Mine is the most suitable mine for the site of the pumped storage power station.
