PROBLEM TO BE SOLVED: To provide a method of charging a coke oven with coal which can increase the quantity of contraction of coke in the neighborhood of the oven mouth on the coke discharge side to smooth thrusting of the coke without adversely affecting productivity of coke, and a method for producing coke. SOLUTION: A scraper 10 is installed movably up-and-down and rotatably above a belt conveyor 2 which leads coal to the center of a coal tower 1, and with the use of this scraper, coal is accumulated so as to bring about the segregation of grain sizes in the oven lengthwise direction in the coal tower in such a state that the grain diameter of the coal on the coke oven discharge side is rendered small, and the coal is loaded onto hoppers of a coal charging vehicle in the above state and is successively fed into a coke oven carbonizing chamber while maintaining the segregation of grain sizes between the hoppers as it is.
