Long-term, extensive overexploitation of coal mining resources has negatively impacted the ecological environment while bringing about economic prosperity. This has resulted in frequent mining geological disasters, particularly coal mining collapses, endangering the lives and property of locals and necessitating an urgent need for ecological restoration and all-encompassing management. For ecological restoration and thorough management, it is necessary to map out information on coal mining collapse on a national scale, including the location, scale, and waterlogging situation. On a national level, however, relatively few academics have examined coal mining collapse until this point. This study uses domestic high-resolution remote sensing data to track coal mining collapse across the country. The findings reveal that by the end of 2018, there were 35,453 coal mining collapse areas with an area of 21,957 km2 ; the area of collapse pits was 14,859 km2 , the area of waterlogged collapse pits was 1,716 km2 , the area of restoration and treatment of collapse pits was 2,712 km2 , and the overall rate of restoration and treatment of collapses was 15.43%. The ecological restoration models of coal mining collapses may be essentially categorized into five categories: the reclamation models for agriculture and forestry, fisheries and ecological wetland, landscape management, urban development, and new energy industry. The findings of this study can, to some extent, be used as data support for the supervision and thorough prevention and control of coal mining collapse in China as well as a source of reference for the ecological restoration of coal mining collapse, both of which have research significance.
