A process method of coking coal dust forming chiefly aims at settling the problem about a second dust emission in the course of transportation. First, the large quantity of small smut produced by a fluidized bed can be collected by a dust precipitator, be conveyed to a smut collecting storehouse, and constantly transmitted into a high pressure molding machine by an incessant closed conveyer. The feeding mouth of the high pressure molding machine is provided with a repressing screw to ensure the smut entering a high pressure rolling pair to be with certain pressure. Then the smut can be extruded into effigurate briquette, which at last is conveyed into a production coal conveying system after the molding. The process can prevent the production coal from producing the second dust emission during the transportation, thus reducing the engineering investment and environmental pollution with the advantages of less floor space and increasing the coke yield produced by coke oven.
