Abstract：In the face of a shortage of high-quality coking coal, utilizing low volatile and lean coal with relatively abundant resources to replace other scarce coal types has become a future trend. The compatibility and compatibility between lean coal and main coking coal from different regions were analyzed, and the best main coking coal that matches lean coal were identified. Using the best main coking coal as the main coal and applying lean coal in actual production, The research results show that using lean coal coking technology can produce high-quality coke with reasonable adjustment of the ratio.
