Abstract: In order to accurately and reliably predict rockburst disasters, AHP was optimized based on importance of analysis index of RF, and an RF-AHP weight calculation method was constructed. Then, a prediction model of rockburst intensity classification based on RF-AHP-Cloud model was established. Finally, through literature survey, a database containing 301 groups of engineering instances was established as sample data for rockburst prediction, and prediction results of 25 sets of samples were analyzed. The results show that the proposed model has an prediction accuracy of more than 88%, and it can determine rockburst intensity grade of samples. And rationality of RF-AHP index weight calculation method as core of prediction model is also verified.
