Overview

Multiphase dust transport dynamics and water mist suppression techniques improved dust removal efficiency in tunnels.

Key Points

  • Dust exhibits vertical stratification based on particle size, affecting its migration during tunnel blasting.
  • Numerical simulations and model tests reveal how nozzle angle and flow rate impact dust removal efficiency.
  • Eddy formation at the working face can be mitigated by adjusting the distance of the air duct outlet.
  • Findings suggest optimizing airflow through careful adjustments can enhance overall dust suppression measures.
