The primary purposes of ventilation are to dilute respirable coal dust, to remove explosive concentrations of coal dust and methane from the working faces, and to remove methane from mined-out areas. In addition to supplying fresh air and exhausting noxious and explosive gases and dusts, mine ventilation systems must furnish paths of escape in the event of an underground fire. Ventilation …
