Coal Mine Ventilation

In coal mines, accumulations of coal dust must be prevented as the substance is both highly flammable and explosive. Many major disasters have been caused by coal dust explosions initiated either by a small methane explosion or other sources of ignition. ... A mine ventilation system must prevent the release of dust into the GBA, and remove air ...
