Density The density of a coal sample is dependent on the rank, type, mineral matter and moisture contents of the coal. The moisture content of a sample will be affected by the manner in which it has been handled, broken, dried, or analysed. The determination (best estimate) of

divided by the total volume of the wet sample; that is, dry-bulk density is the ratio of the mass of the mineral grains to the total volume. All index properties are essentially ratios of masses and volumes. Therefore, dry-bulk density can be calculated directly from mass and volume measure-ments, or by relationships with other index properties.
