Abstract

Micro-Raman spectroscopy examination of 20 samples of coking coals (R_r=0.84-1.43%) was performed. Spectral parameters were correlated with the basic rank and technological properties of coals. The G band FWHM and the A_G/A_ALL ratio decrease with the volatile matter content (V^daf) decrease and the all maceral reflectance scan (R_scan) value increase. The correlations between these parameters are stronger than those, between the G band FWHM and the A_G/A_ALL ratio, and the mean random vitrinite reflectance (R_r). Coking properties are weakly related to the Raman spectral characteristics of coal. Based on the Raman parameters G band FWHM and the A_G/A_ALL ratio, it may be possible to evaluate the volatile matter content (V^daf) and the all maceral reflectance scan (R_scan) value for coking coals.
