The application discloses a coking coal caking index determination method based on granularity compensation and belongs to the technical field of detection. R.I. When G is 18, the coking coal caking index G is accurately determined through the following formula I: G=G R.I. -a*(35-A) I, wherein A is the proportion of coal samples with a granularity of 0.1mm-0.2mm in the sample, the value of A is 20-35, the value of a is 0.11 or-0.18, G R.I. is the caking index determined according to the coking coal caking index determination method in GB / T 5447-2014, and the formula for determining the coking coal caking index is constructed on the basis of considering the granularity, the G value result is accurately reported, and it is very necessary to reduce the quality abnormality of both supply parties.
