Abstract: Under the backdrop of the "Dual Carbon" strategy, China faces unprecedented opportunities and challenges in shutting down the development and utilization of mining resources. This paper reveals the current state of sustainable development in closed mines in China through a multidimensional analysis of policies and regulations, environmental governance, socio-economic impacts, and technological management. By incorporating typical case studies, it summarizes the research achievements in areas such as ecological restoration, underground space utilization, and the development of other potential resources in closed mines, and identifies existing problems in the sustainable development of closed mines. Through the study of existing policies, regulations, and standard norms regarding mine closure and withdrawal, comprehensive utilization of mine water, underground thermal energy development, environmental impact assessment, land reclamation, and ecological restoration, the paper suggests continuously strengthening political leadership and improving regulatory policies, accelerating the establishment and enhancement of resource standard evaluation systems, enhancing inter-departmental collaboration and institutional innovation, and promoting the integration of policy innovation with technological advancement. These measures aim to provide policy support and crucial guarantees for the sustainable development of closed mines.
