Evolution and mechanism of rockburst induced by structural plane based on GDEM

Meitan xuebao, 2023
In the process of deep underground rock excavation, the surrounding rock of cave wall often causes some rockburst geological disasters due to the weakening of structural plane. In order to reveal the influence of the existence of structural plane on the rockburst induction mechanism, in this paper, adopting the finite element and discrete element ...

Dynamic buckling mechanism of pillar rockbursts induced by stress waves

Journal of Rock Mechanics and Geotechnical Engineering, 2019
Rockbursts are sudden and violent rock failures that can lead to huge production and equipment losses, injury or death of mining workers. Buckling has been regarded as one of the key mechanisms of rockbursts, which are often induced by dynamic loads from mining excavations, such as drilling and blasting in underground mining.
