The reuse of abandoned mines is not a pure ecological project but a complex social public project. While it is unsustainable to reuse abandoned mines without ecological restoration, such restoration without comprehensive resource utilization will cause a serious waste of resources. Therefore, to reduce the contradiction between ecological restoration and resource utilization in the process of reusing abandoned mines, there is an urgent need to research the classification, grading development, and utilization evaluation index system of abandoned mine resources. Based on the concept of “energy, resource and functionalization” three-dimensional coordinated development and utilization, this paper analyzes the value connotation of abandoned mine reuse and constructs an evaluation index system for the reuse value of abandoned mine resources, including resource conditions, ecological conditions, and development conditions. Secondly, according to the priority needs of abandoned mine reuse, the minimum factor method is used to design a development sequence that can take into account the reuse of abandoned mines and the coordinated development of the ecological environment and the region. On this basis, the value of abandoned mine reuse is divided into four grades and three development stages. Taking the Jingxi Mining Area as an example, corresponding development and utilization suggestions are proposed, and the guiding value of the evaluation index system in assessing resource potential and optimizing of development paths is verified. The research results can provide scientific decision support for planning the development and utilization of abandoned mine resources. They also have practical significance for constructing green development technology standards and promoting ecological restoration and industrial transformation and upgrading in mining areas.
