The exploitation of coal mine resources has greatly contributed to China’s economic development, but it has also caused damage to the surrounding ecological environment. With the adjustment and optimization of the national energy structure, many small or unqualified mines have been closed in recent years. Thus, the environmental treatment and ecological restoration of these closed coal mines need to be carried out urgently. In this study, the causes of closed coal mines are analyzed from the perspective of macro policy. Then, the key technical difficulties of comprehensive and systematic restoration and treatment of geological and ecological problems are discussed from multiple perspectives. Finally, the successful restoration and treatment cases of closed coal mines locally and globally are showed. The findings of this study provide ideas and methods for ecological environment restoration and management of closed coal mines.
