Explore the development context and research hotspots of coal workers' pneumoconiosis in China in the past two decades. Based on the data source of 1,485 related research literatures on coal workers' pneumoconiosis collected by CNKI, CiteSpace was used to draw a visualized knowledge map of authors, publishing organizations, and keywords, and the relevant literature was reviewed. The results show that since 2000, the number of publications has increased first and then decreased, and coal workers’ pneumoconiosis related research has entered a cooling period; the research hotspots are pathogenesis, treatment, diagnosis, and epidemiological research. Based on the hot content and development context of coal workers' pneumoconiosis research, it is recommended to continue to strengthen the research on the pathogenesis and diagnosis and treatment measures of coal workers' pneumoconiosis. At the same time, based on the actual life of patients, we are committed to improving the quality of life of patients in an all-round and full cycle.
