Abstract:
Using a self-developed impact rockburst equipment, the rockburst phenomena of surrounding sandstone of elliptical caverns under true triaxial loading were reproduced. The stress acquisition system, real-time video recording system and acoustic emission(AE) system were used to investigate the sandstone rockburst failure. Specifically, the failure characteristics such as stresses, fragments, rockburst pits, velocity field and AE were discussed in detail.
