Coking coal classification method, coking coal blending method and application

The invention discloses a coking coal classification method, a coking coal blending method and application. The coking coal classification method comprises the following steps: dividing coking coal into lean coal, coking coal, 1/3 coking coal and gas coal; and obtaining the vitrinite random reflectivity and the mineral catalysis index of the coking coal, and classifying the coking coal according to the vitrinite random reflectivity and the mineral catalysis index of the coking coal. According to the classification method for the coking coal, precious coking coal resources can be utilized more reasonably and fully, it can be guaranteed that the coal blending scheme is conveniently adjusted when the conditions that raw material coal changes and the like occur in the actual production process, and it is guaranteed that the quality of coke is stable. 本发明公开了一种炼焦煤的分类方法、炼焦配煤方法和应用，其中炼焦煤的分类方法包括：将炼焦煤分为瘦煤、焦煤、1/3焦煤和气煤；获取焦煤的镜质体随机反射率和矿物质催化指数，根据焦煤的镜质体随机反射率和矿物质催化指数对焦煤进行分类。本发明所述的炼焦煤的分类方法，能够更合理、充分利用珍贵的炼焦煤资源，也能保证在实际生产过程中遇到原料煤发生
