Abstract

This paper introduces the application of coal and rock analysis in coking plants. Coal and rock analysis can identify the quality of incoming coal through the distribution of vitrinite reflectance, effectively distinguishing between different types of coal and mixed coal conditions. This helps optimize coal blending schemes, improve the coal blending ratio, and stabilize coke quality. By combining the distribution of vitrinite reflectance and the activity-to-inactivity ratio from coal and rock analysis, it is possible to accurately predict the cold and hot properties of coke, stabilize coke quality, and guide coking coal blending. The research findings indicate that coal and rock analysis can identify the quality of incoming coal through the distribution of vitrinite reflectance, effectively distinguish between different types of coal and mixed coal conditions, thereby optimizing coal blending schemes, improving the coal blending ratio, stabilizing coke quality, and guiding coking coal blending.
