The data and information, retrieved in the past ten years with "mining heritage " as keywords, was visualized and analyzed through the theory of knowledge graph by Citespace software. Different maps were illustrated, such as the keyword spectrum, the keyword time-zone view analysis map, co-occurrence map, emergence diagram. Research hotspots and forecast prospects were further summarized, so as to promote the theoretical progress and practical optimization of mining heritage. It could be found that mining heritage should focuses on its ecological restoration, value evaluation, comprehensive utilization of underground space, and research on tourism development models. This study believes that the future of mining heritage should be developed from the following aspects: 1. Strengthen the research on the management of mining heritage ecological environment design, implementation and reform; 2. Strengthen the research on the goals of mining value, and promote the establishment of a "National Mining Heritage List"; Natural resource tourism development, exploration of the development mechanism and integration model of cultural tourism; 4. Systematized research on the tourism development strategy of mining heritage; 5. Strengthen the heritage perception of cross-regional and cross-industry types related to mining heritage, such as coal transportation Genetic corridors, etc.
