The major risk factors on break-dam were identified by using the Delphi method,and the risk evaluation index system of break-dam was established. The index weights of break-dam in mine tailings pond were calculated by using GA- AHP. The evaluation index was classified to establish the risk assessment model based on the GA- AHP and cloud-matter element model. The established model was applied to practical case,and the Matlab software was used to calculate the subordinate degree. The results showed that the risk of break-dam in the mine tailings pond is normal and the evaluation results are consistent with the practice. mine tailings pond; break-dam risk evaluation; GA-AHP; cloud-matter element model; subordinate degree |
