A method is claimed for charging coke ovens with coal by: passage of coal through charging holes and simultaneously withdrawing gases evolving from the coal charge through the middle charging holes thereof; holding the coal charge over a period of time sufficient for a coal-charging machine to deliver a next batch of said coal charge for charging the next successive coke oven; completely charging said coke oven while simultaneously charging the next successive coke oven through its extreme charging holes; withdrawing through said middle charging holes of said coke oven being completely charged, said coke-oven gases; and introducing a gas inert to said cokeoven gas in an amount of 15-20% of the total amount of the cokeoven gas being withdrawn. There is also provided a coal-charging machine for carrying out this method comprising a frame with undercarriages, hoppers for containing the coal charge, the number of hoppers corresponding to the number of the charging holes of the coke oven, coal feed devices disposed in the upper portion of the hoppers.
