Role of Coal Properties and Surrounding Rock Stiffness in Coal Burst Triggering Under Superimposed Dynamic Loads During Deep Mining

Key Points

• Coal burst triggering is significantly influenced by coal properties and surrounding rock stiffness under dynamic loads.
• A critical threshold of rock stiffness correlates with increased coal burst incidents during mining operations.
• Observational analysis identifies how varying coal properties impact vulnerability to bursts amidst dynamic conditions.
• Understanding these interactions supports strategies to enhance safety in deep mining environments.
