Shortage of coking coals has led to increasing interest in identifying suitable coals for coking blends. In many countries vitrinite reflectance measurement has been used for on-line assessment of charge characteristics. In the USSR this method is gaining in popularity and the paper quotes an example involving reflectance measurements at 100 points on a polished seam sample section, using microscope and multiplier, to produce a histogram. Four blends were prepared, each corresponding to standard gas coal (35%) and fat coal (65%) requirements, to define blend components. The fat coal showed vitrinite reflectance between 0.85 and 0.97%, and the gas coal >0.97%.
