    OverviewRisksEnergy generationSee alsoExternal links

    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. It 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. However, coal dust is hazardousto ers if it is suspended i

  • What Is the Environmental Impact of Mining and Burning Coal

    Burning coal emits large amounts of carbon dioxide into the atmosphere. Coal is composed almost entirely of carbon, so burning coal unleashes large amounts of carbon dioxide (CO 2) into the atmosphere. These emissions have been shown to increase the greenhouse effect in the atmosphere and lead to global warming. Subsurface coal mining is dangerous.
