Abstract: Mine ecological restoration is an significant part of the integrated management of "mountains-rivers-forests-farmlands-lakes-grasslands", and the treatment and disposal of municipal sludge is also a key research direction in urban environmental issues. Given the lack of soil for mine ecological restoration substrate and the limited disposal options for stabilization products of municipal sludge, more and more researches have begun to focus on the possibility of applying municipal sludge to mine ecological restoration. This study reviews the application prospects of stabilization products of municipal sludge in mine restoration and analyzes the ecological benefits, including improving soil physical and chemical properties, preventing leaching pollution in mines, and enhancing the remediation effect of plants on soil containing heavy metals. It is suggested that the application of stabilization products of municipal sludge in mine ecological restoration also has certain secondary pollution risks. The accumulation of ecological toxicity may significantly reduce the survival rate of mine plants, and leaching of substances such as nitrogen and phosphorus may pose a risk of groundwater pollution. Therefore, it is necessary to control the usage and dosage of stabilization products of municipal sludge. The research shows that further clarifying the long-term impact of municipal sludge application on the physical and chemical properties of mine soil, deepening the mechanism of fixation of heavy metals by municipal sludge stabilization products, clarifying the optimal application amount and application method of municipal sludge stabilization products, and establishing the pollution assessment method after municipal sludge application are important research directions in the future.
