Abstract: The problems of water pollution in coal mining areas are especially evident, and developing circular economy is the fundamental way to solve it. By analyzing Daizhuangmine’s status of water resources, this paper summarizes thismine’s circular economy model mainly relying on wastewater cyclic utilization. On this basis, the paper makes a detailed study on water treatment and recycling of mine, sewage, power plant and coal washery. Study on Daizhuangmine’s water recycling shows that comprehensive utilization of mine waste water and significant economic benefits have been realized in this mine.
