摘要

Coal Dilatation Measurement Method, Coal Specific Volume Estimation Method, Interparticle Space Fill Capacity Measurement Method and Coal Blending Method The present invention relates to a coal expansion dilatation method which includes: loading a coal into a dilatometer tube; inserting a piston into the expansion tube; heating the coal so that the rate of temperature rise in the plastic coal stage is 6 ° c / min or greater; measurement of a piston displacement; and obtaining coal expansion from displacement.
