The invention discloses a method for applying a biomass extract product to coal blending for coking as an additive. The method comprises the following steps: (1) extracting biomass with an organic solvent, and obtaining a high molecular weight biomass extract and a low molecular weight biomass extract; and (2) applying the biomass extract to coal blending for coking, namely mixing and coking at least one of the high molecular weight biomass extract and the low molecular weight biomass extract with mixed coal at the mass percent of 0.5%-3%. By mixing and coking at least one of the high molecular weight biomass extract and the low molecular weight biomass extract with the mixed coal, the coke reactivity PRI of coke particles can be lowered on the basis of common mixed coal, and the strength of the prepared coke is greatly improved, so that the use ratio of weakly caking coal or non-caking coal in the mixed coal is increased under the premise of ensuring good strength and low coke reactivity of the prepared coke; and the coking cost is reduced.
