calculating coal relative density

  • Coal, Kentucky Geological Survey, University of Kentucky

    If the purpose of the calculation is to obtain a general estimate for the tonnage of coal on a property or a regional average resource estimate, site-specific information (the details of coal composition) are not needed and an average coal density is commonly used for the calculation. Relative coal density is measured as specific gravity.

  • Relative density - Wikipedia

    Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. The term "relative density" is often preferred in scientific usage.

  • Coal assay - Wikipedia

    Relative density. Relative density or specific gravity of the coal depends on the rank of the coal and degree of mineral impurity. Knowledge of the density of each coal play is necessary to determine the properties of composites and blends. The density of the coal seam is necessary for conversion of resources into reserves.
