Аннотация
Abstract—For Kuznetsk Basin coal of different metamorphic stages, the fundamental difference between determining the limiting wetting angle of a coal surface by means of a hanging bubble and a sitting droplet is determined. The influence of surface preparation (briquetting of powder, plane cleavage, or surface polishing after plane cleavage) on the limiting wetting angle is investigated. The methodological features of sample preparation that affect the determination of coal wettability are identified.
