On the basis of practice，by means of testing and analyzing theproximate analysis, agglutination index, plasticity index , Audibert-Arnu dilatation, vitrinite maximum reflectance, petrographic constituents of some common coals, nine blending coals precepts are got according to different mixing proportions. Properties of coke produced from 20 kg coke oven such as quality, sieve classification constitution, shot coke reactivity, micro-strength are experimented and analyzed, and the best mixing proportion scheme is got to produce the second class metallurgical coke. Mixing some powdered coke into coal can improve the blockness and abrasiveness on condition that the caking properties is sufficient.
