Abstract: The meager lean coal, after fine crushing, coked compatibility with gas-fat coal, fat coal, 1 / 3 coke coal and coking coal by weight ratio of 1:1. The results showed, to ensure quality of coke, if the mixture ratio of meager lean coal was improved, the blending coal must have amount of fat coal and gas-fat coal and moderate to restrict the amount of coking coal and 1/3 coking coal; In the coking process, the expansion and mobility of 1 / 3 coking coal is far less than the gas-fat coal and fat coal, so when it coked with the meager lean coal, the result was different from the conventional coking mechanism.
