A method for the preparation of coal charge for coking comprises batch preparation from coal concentrates, determination of optimal fragmentation size according to content of class 0-, charge dozing, and its grinding. At batch preparation a grade composition is formed, providing maximum possible value of optimality coefficient of charge grade composition, calculated according to the equation. Coefficient values characterizing base content of coal of different grades are determined according to results of reflectogram analysis during periods of high quality coke production at particular coke-chemical enterprise. |
