Zusammenfassung:The invention discloses a large-scale coking coal cake tramping method. The method comprises the following steps: taking coking coal, 1/3 coking coal, rich coal, meagre coal and gas coal as raw material coals, performing coal preparation according to a preset coal blending scheme and granularity requirement, tamping according to the set tamping condition, tamping the height of the coal cake to a height being 7.1 meters, and successively pushing into a coke oven, wherein, the collapse rate is lower than 0.3%. According to the invention, the method can greatly reduce the usage amount of high-quality coking coal, coal with weak caking property and coal with non caking property are doped, so that high-quality coking coal resource can be protected, cost is reduced, pollution is reduced, and production capacity in a single charing chamber can be increased.
