Study on Risk Assessment Method for Tailings Pond Disaster Based on Improved Index Weight Method

Abstract:

In order to evaluate the risk degree of the tailings pond’s dam-break disaster reasonably, according to statistical analysis of the tailings pond’s dam-break failure and "the tailings major hazards classification method" of our country, the improved "index weight method" is worked out, and the index partition method and weight assignment of the "index weight method" are analyzed and researched detailed. Combining with an engineering example to verify the improved "index weight method", and the sensitivity of index weight is discussed. The results of the analysis show that "index weight method" for the judgment of the risk degree of the tailings pond’ s dam-break disaster is more reasonable. It is more feasible for safety department to make division of attention to supervision level of the tailings pond according to the determination results.
