A method of charging coal into a chamber furnace-type coke oven. The coal is fed from a table feeder from a coal hopper so as to be dropped and charged into a carbonization chamber of the coke oven, through a charging cylinder. The coal fed from the table feeder is accelerated by rotation vanes at the initial stage in which the coal starts to drop. The vanes have a rotation center which is located upward on the exterior of a locus of the stream of free fall gravitated by the coal. The rotation speed of the vanes is progressively increased in the latter half of charging of the coal. The coal is thus allowed to accumulate in the carbonization chamber so that the bulk density of the coal in the vertical direction can become uniform. Also disclosed is an apparatus for charging coal into a chamber furnace-type coke oven. The apparatus includes a coal hopper for storing the coal therein. A table feeder feeds the coal from the hopper. Rotation vanes increases the speed of the coal fed from the feeder at the initial stage in which the coal drops from the feeder. The vanes have a rotation center which is located upward on the exterior of a locus of the stream of free fall gravitated by the coal. A charging cylinder guides the coal, which has been accelerated by the vanes and dropped into the carbonization chamber.
