Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal. Blasting at mountaintop removal (MTR) sites also expels coal dust and flyrock into the air, which can disturb or settle onto nearby communities.
