对细粉碎后贫瘦煤，与气肥煤、肥煤、1/3焦煤及焦煤按重量比1:1 进行配伍共结焦实验。研究结果表明：在保证焦炭质量的前提下，要提高贫瘦煤的配入量，必须有充足的肥煤和气肥煤配入量，适度限制焦煤和1/3焦煤的配入量；1/3焦煤在结焦过程中的膨胀性和流动性远远低于气肥煤和肥煤，因此其与贫瘦煤共结焦结果不同于常规的结焦机理。
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.
