Determining the cause-and-effect relationships responsible for coal Properties 4. Assessing the influence of mineral impurities on the organic mass of coal

Abstract

Coal may be regarded as an organic–mineral complex formed by the accumulation of sediments and their metamorphic transformation to sedimentary rock. On that basis, Kuznetsk Basin coal may be analyzed in terms of the corresponding genetic characteristics of gelification and reduction and the chemical composition of its ash. The influence of mineral impurities on the organic mass of coal may best be assessed on the basis of integral characteristics: the oxide moduli in assessing mineral impurities; and the genetic benefit K^gb for the organic mass. The genetic benefit provides information regarding the molecular structure and mineral composition of the coal.
