The experiment was designed to study the coking coal swelling characteristics as a function of particle size distribution and density under thermal shock. During the cokes making process, coking coal pass through the fluidity zone at specific temperature. Cokes characteristics can be caused by physicochemical properties at fluidity zone. Three kinds of coking coal was used for experiment and each coal has different swelling characteristics. Softening and swelling characteristics was analyzed through the permeability test. Permeability test was performed by measuring the differential pressure of nitrogen. Finally, It compared blending effect by the swelling characteristics. Three kinds of coking coal was blended A with D and D with G in specific ratio. Coal "D" is standard of comparison. As a result, D:A blended coking coal has generally low permeability characteristics (1.0~1.2bar). Because It strongly combined with each particle after mesophase zone. This characteristic derives from FSI and volatile matter contents. And D:G blended coking coal test results seem to decrease with coal "G"contents. It means, coal "G" has not sufficient swelling characteristics.
