The analysis of the result of the regression analysis of the modeling of the quadratic relationship of germanium with the ash content of the coal seam с8в of the "Dniprovska" mine clearly indicates the existence of a relationship between the maximum values of the germanium content in coal and the ash content interval within 5-10 %, which reflects the so-called "sorption optimum". It was established that, all other conditions being equal, with a decrease in the thickness of the formation as a whole, the contribution of its areas enriched in germanium to the total content of this metal in the considered formation will increase. At the same time, in some cases, these enriched layers will be join and the entire coal seam will be a continuous zone of enrichment. This explains the limitation of almost all abnormally high values of germanium content to areas of the seam with a thickness of no more than 0.4 m.
