    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 is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.
