  • Coal Density

    Coal is a porous material and, thus, the porosity and surface area of coal have a large influence on coal behavior during mining, preparation, and utilization. As already noted with respect to coal density the porosity of coal decreases with carbon content and has a minimum at approximately 89% w/w carbon followed by a marked increase in porosity.
