The stability, monitoring, pre-alarming, and sustainability of tailings dam are crucial for mining disaster control, environment, and human beings. The paper introduces the damage of tailings dam failure by 44 typical accidents (2138 deaths in total), and then presents some developments and new insights for environmental sustainability and disaster control of tailings dam. Firstly, three kinds of methods for stability analysis of tailings dam were summarized and compared. Limit equilibrium methods (LEMs) were focused on Sweden methods, Janbu method, Bishop method, and Morgenstern-Price method. Numerical simulation methods were discussed about finite element method (FED), discrete element method (DEM), boundary element method (BEM), and finite difference method (FDM). Uncertainty methods were compared, including gray system evaluation method, reliability method, and fuzzy evaluation method. Secondly, the research progress in the field of safety monitoring and pre-alarming of tailings dam was reviewed, covering the aspects of traditional monitoring methods and coupled monitoring systems. Finally, the conception map of disaster prevention, disaster control, and environmental sustainability for safety management and environment to enhance cleaner production work in tailings dam was presented. The map for safety work and environmental sustainability achieves the goals from "lagging" to "real time", from "point" to "solid", from "surface" to "internal", and from "passive" to "coupled passive and active".
