Abstract:
In this paper, the definitions and mechanisms of rockburst proposed by authoritative experts are reviewed. On this basis, rockbursts are divided into the sliding mode resulted from fault slip or shear rupture and the strain mode due to rock failure according to different mechanisms. The mechanism and characteristics of two types of rockburst and pressure bump are analyzed with case studies. The quantitative prediction results for strain burst in rock (coal) pillar, strain burst and fault-slip rockburst in the surrounding rock masses are presented. The latest research achievements on quantitative prediction and numerical simulation of strain burst by considering the effect of the non-compatible deformation using the non-Euclidean geometry model are introduced.
