Abstract: Petrographic analysis of coal and charge was carried out in reflectogram mode. It is shown that reflectograms are an effective means of quality control of coals supplied for coking. Changing the shape of the reflectogram allows you to predict possible changes in the production process when using various charges.
Reflectogram analysis of coals for coking in combination with petrographic indicators and with the consideration of the petrographic heterogeneity of Kuznetsk coals makes it possible to determine most accurately their properties when compiling coal charges and this contributes to the choice of the direction of blending, thus ensuring the rational use of coal concentrates. This is especially important when the concentrates are represented by several grades or types of coals that have similar quality indicators, but with different sintering properties.
