Claim:
A method for compacting coal into coal compacts which exhibit reduced coking time in a coke oven chamber, comprising pressing and compacting coal with a moulding pressing device into one or a plurality of coal compacts, wherein the moulding pressing device comprises a mould that shapes the surface of the coal compacts to provide a structured shape on the surface that is not planar and thus possesses an increased surface area in comparison to coal compacts which are not structured on the surface, and the moulding pressing device is provided with plates mounted perpendicularly on it from four sides so that an enclosure is created which is filled for compacting and pressed with other moulding plates, and the laterally mounted plates also bear structure-providing moulding elements at the inner walls and the plate on the non-frontal side of the coal cake is also provided with structure-providing moulding elements.
