Millisecond Delay Time Optimization and Its Effect on Blasting Vibration Reduction in an Open Pit Mine

Key Points

• Blasting vibration reduction was achieved with optimized millisecond delay time, enhancing operational efficiency.
• The study showed a significant decrease in vibration levels by up to 20% in response to delay time adjustments.
• Observational analysis in an open pit mine demonstrated the relationship between delay timing and vibration impact.
• Optimization techniques may enable safer blasting practices for surrounding infrastructures, reducing damage risk.
