Abstract

In order to evaluate rockburst in deep mining, with Tiaoshui river Phosphorite Mine being taken as an example, a comprehensive evaluation system of 3 rockburst proneness indexes e0 / ec 、e1 / ec 、ec / et were put forward, and comprehensive weight method which was able to eliminate cloud atomization was adopted to develop an improved finite cloud evaluation model for roof multi-index rockburst proneness. Then, stress value of the stope was calculated by FLAC3D, and parameter values of e0 / ec 、e1 / ec 、ec / et were obtained. Finally, evaluation experiment on Tiaoshui river Phosphate Mine was carried out, and rockburst proneness of its top slab was determined according to the principle of maximum membership. The results show that the roof of its deep stope has a weak rockburst proneness, which is consistent with actual situation. Compared with the results of other methods, this model features good accuracy. Moreover, control measures, like identification, supporting and monitoring of rockburst hazard areas, are proposed. © 2022, Editorial Department of China Safety Science Journal. All rights reserved.
