Failure evolution mechanisms and coupled static-dynamic loading of multiple thick hard strata in 10 m ultra-large mining height

Key Points

• Failure mechanisms evolve significantly under static and dynamic loading conditions, affecting mining safety.
• The analysis revealed key behaviors of hard strata under different loading scenarios, emphasizing the importance of understanding these mechanisms.
• Assessment of interaction between static and dynamic loading provides insights into potential structural failures during mining operations.
• Understanding these mechanisms is crucial for improving safety measures and mining practices in ultra-large height operations.
