摘要：
The properties of mixed coals were studied on the basis of known various properties of the injecting coals in the treatise. The structure of the injecting coals was optimized and put into practical application. It was found that the ignition point was lowered with mixed coals, however, both combustibility and grindability were improved, and explosibility of the mixed coals were decreased as well. Hence, mixed coals injection not only can improve the amount of the injecting coals greatly, but also improve the economical and technical indexes of the blast furnace.
