Models of Spectral Classes of Coal

摘要

Models are developed for spectral classes of GZh and Zh coal concentrates based on diffuse-reflection IR spectra, by independent modeling of class analogs. The spectral classes derived for such coal are shown to be clearly distinct. Individual models of spectral classes for samples of GZh and Zh concentrates from different enrichment facilities are created and compared. On the basis of the spectral classes, which reflect the chemical structure of a limited mass of coal, the coal rank may be established, and concentrates from different enrichment facilities may be compared and contrasted. In addition, rapid quality control is possible.
