Zusammenfassung:The invention relates to a coal blending and coking method for controlling the proportions of strongly caking coals. The method comprises the following steps: (1) calculating colloid mass characteristics C of various strongly caking coals in a pre-adjustment coal blending scheme; (2) classifying the strongly caking coals according to the colloid mass characteristic C and the Gieseler maximum fluidity (MF), and determining a contribution coefficient; (3) selecting substitute coal according to vitrinite average random reflectivity Rr and the MF of to-be-substituted coal in the pre-adjustment coal blending scheme; (4) determining the weight percentage of the substitute coal in an adjusted coal blending scheme according to a formula as described in the specification; and (5) adjusting the proportion. By adjusting the coal blending scheme through the method, a stable range of coke quality can be guaranteed; and compared with the pre-adjustment coal blending scheme, the adjusted coal blending scheme has the advanta
