The aim is to understand airflow and dust behavior in blind tunnels of underground hard-rock mines.
Investigated gas-solid flow using Euler-Lagrange computational methods.
Released fine dust particles under various turbulence and thermal conditions.
Analyzed airflow velocity, pressure, temperature, and turbulence effects.
Observed non-uniform airflow with localized high-speed jets reaching 62.5 m/s.
Dust simulations indicated fine particles stayed suspended in low-velocity zones.
Hybrid-duct configuration generated highest turbulent kinetic energy around 9.4 m²/s².
