Overview

Numerical simulation identifies key factors affecting dust removal time in tunnel blasting, highlighting ventilation's role.

Key Points

  • Reducing roadway dust concentration to 10 mg/m3 takes about 53 minutes after blasting.
  • Main factors affecting dust removal time include tunnel length, airflow rate, and ventilation distance.
  • A predictive model established the relationship between dust removal time and ventilation factors.
  • Validation shows the model’s high accuracy, suggesting practical applications in tunnel ventilation optimization.
