Abstract

Using the self-developed real triaxial rock burst experimental system and the established rockburst experiment method, the rockburst experiment of granite with different loading types was carried out. Ejection fragments were screened and carried out statistics, and the particle size distribution of the ejection fragments under different loading types was obtained. The size of crumb is divided into coarse granular, medium granular, fine granular and granular debris, and the scale ratio of coarse granular debris is calculated. The geometrical characteristics of ejection fragments of granite biaxial rockburst test under different loading types were compared, and the similarities and differences were found. The research results can be used as the basis for identification of biaxial rockburst and identification of rockburst.
