Zusammenfassung:FIELD: drying solid materials. ^ SUBSTANCE: method comprises pilling raw coal, allowing the pile to stand for a time interval wherein the coal slips down, breaking the layer of dried coal on the slope, and removing the dry fine coal. The natural angle of the slope of the raw coal is 55-65°. The duration of drying on the southern slope is 5-6 days, and on the northern slope is 7-10 days. Before removing the dry fine coal, a layer of 100-120 mm thick is broken down. ^ EFFECT: enhanced efficiency and quality of drying. ^ 1 cl, 2 dwg
