【Abstract】 In order to improve the objectivity of weight quantification and fully consider the dynamic influencing factors of tailings dam failure, so as to meet the needs of dynamic informatization development of mine safety evaluation, a dynamic risk assessment model of extension cloud dam collapse based on structural entropy weight-numerical simulation was established. According to the dynamics and inherentness of the evaluation indicators, a dynamic evaluation index system for the risk of dam failure in tailings reservoir was constructed. The comprehensive weights of evaluation indicators were calculated by using the structural entropy weight method and numerical simulation software to improve the objectivity of weight quantification. Introducing the theory of material element extension and the cloud model, the dynamic risk assessment model of tailings dam failure based on the extension cloud model was constructed, which is applied to the dynamic risk assessment of a tailings dam failure. The dynamic risk level was evaluated and the recommended measures were put forward.
