Formation mechanism of coke pores is investigated based on the visualization and digital treatment of laser microscopic observation in order to estimate porosity of cokes prepared from coking and non-coking coals including their blended coals under various conditions. The estimated porosity of the cokes by multi-layered image analysis was well correlated with the coke properties including mechanical strengths previously evaluated, successfully revealing the influences of the different heating rate during carbonization and the different blending ratios on their changes, although the estimated values of the porosity by the multi-layered image analysis method were a little bit lower compared to their real values measured by JIS method. Modeling of coke pore formation in the relation to the mechanical strength is discussed based on the above results.
