摘要：

There are tens of thousands of abandoned coal mines in China, reforming the left space into pumped storage power stations can improve the installed capacity, stabilize electrified wire netting, consume new energy, promote energy conservation and emission reduction, which can realize the recycling of abandoned mine resources. It is of great economic benefit, ecological value and social and environmental significance to carry out the study on the key technologies and engineering demonstrations of new energy storage in abandoned mines. In this paper, resources of abandoned coal mines are analyzed based on the principles especially the site selection of pumped storage, and a multi-energy complementary utilization model of pumped storage power stations in abandoned mines is proposed considering the concept of whole life cycle utilization in coal mine. Taking the Shitai Coal Mine as an example, a detailed scheme for the multiple energy sources is carried out based on the comprehensive analysis of mine hydro-geology, resource conditions, and new energy resources. The feasibility of reforming the abandoned mines as pumped storage station is demonstrated from the perspectives of resource conditions, technical level, and economic and social benefits. Suggestions are proposed for the construction of pumped-storage station in Shitai Coal Mine. The research results enrich the utilization modes of abandoned mines, which has great significance for the sustainable utilization of the space resources left in abandoned mines, as well as the transformation and upgrading of energy-oriented cities. © 2023 China University of Mining and Technology.
