Coal inherent factors except for the moisture and particle size which affects coal bulk density were investigated by using sieved coal particle. Circularity of particle is wide ranged among coals, and bulk density becomes larger in higher circularity coal. Packing property of coal also seemed to be affected by porosity of coal.
