Effective ventilation in underground mines is essential to reduce hazardous dust concentrations. This study develops a non-stationary mathematical model of airflow velocity and dust transport in mine corridors based on momentum conservation and convection-diffusion equations. The results show that increasing the pressure difference from 30 to 45 Pa increases the airflow velocity from 2.8 m/s to 3.1 m/s (10-11 %). Correspondingly, the maximum dust concentration decreases from approximately 1 mg/m 3 to 0.82-0.85 mg/m 3 (15-20 %). Numerical simulations in MATLAB confirm the analytical results. The proposed model provides a basis for optimizing ventilation systems and improving safety in underground mines.
