Abstract: With the adjustment of China's energy structure, decentralized coal mining has been transformed into refined, centralized and precise mining, which greatly reduces the number of coal mines in China.And a large number of coal mines with exhausted resources and backward production capacity are facing closure or abandonment.This transformation will confront China, at present and for a long time in the future, with a "post-mining" era similar to that in Germany.From the development trend of the transformation of China's energy structure and the macro strategy of coal resource development, there is no possibility to re-develop those coal mines that have been closed or will be closed.The closed mines not only cause environmental problems such as water and air pollution, but also social and economic problems such as difficulty in relocating employees and disposing fixed assets.Therefore, in view of the problems after the mining area is closed or abandoned, the treatment plans for post mining and the sustainable development strategy of resources in post mining industrial zone in Germany are referenced in this paper.Compared with the treatment schemes of closed mining areas in China, the concept that the utilization of resources after the closure of mining areas should be included in the top-level design of the whole mine development, and the idea of comprehensive utilization of coal underground space, mine water and other resources are proposed.Although various forms of abandoned mine utilization schemes have been put forward at home and abroad, the overall utilization rate is not high.It is still necessary to further explore the basic theories and methods of resource utilization in closed mining areas, as well as the corresponding education and technical personnel training measures to meet the development of these areas.
