Mechanism and practice of structural modification to lateral overlying strata in gob-side entry for rockburst prevention [PDF]

open access: yes
Pillarless (or small-pillar) mining method has been widely used. With increasing mining depth, the hard rock in the overlying strata leads to high stress concentration, extensive damage, and frequent high-energy dynamic events, which has become a major ...

Research on the Outburst–Rockburst Coupling Disaster Law Based on True Triaxial Unloading Tests

open access: yes
The coal and gas outburst and rockburst coupling disaster is becoming increasingly serious due to deep mining. To clarify the mechanism inducing the outburst–rockburst coupling disaster, a true triaxial single-sided unloading mechanical test was ...

Self-initiated static-dynamic state transition behavior and triggering mechanism of strain rockburst using three-dimensional discrete element method

open access: yes
The accurate understanding of rockburst mechanism poses a global challenge in the field of rock mechanics. Particularly for strain rockburst, achieving self-initiated static-dynamic state transition is a crucial step in the formation of catastrophic ...
