ABSTRACT OF THE DISCLOSURE A method of restricting dust formation when coal, and particularly preheated coal, is fed into coke ovens is disclosed. According to one aspect of the method, the coal is contact with an aqueous solution containing between 30 and 70 percent by weight of a substance which is capable of binding dust-like coal particles. The contacting operation is performed prior to the introduction of the coal into the coke ovens. The solution is used in quantities of 0.5 to 1.0 parts by weight per 1000 parts by weight of the coal. The solution may include a surfactant and, further, may be mixed with coal tar. According to another aspect of the method, the coal is simply contacted with 0.5 to 3 percent by weight of coal tar be- fore being introduced into the coke ovens. Preferably, the coal tar is derived from the coking of the same type of coal or coal mixture as is to be fed into the coke ovens. The coal tar is fav- orably heated prior to being contacted with the coal. The coal tar likewise serves to bind dust-like coal particles. - 1 -
