Scope

This document specifies the basic technical requirements, operating procedures, and methods for automatically determining the pore structure of coke and the random reflectivity of vitrinite in raw coal using petrographic microscopy analysis methods, as well as the instruments and equipment required. This document is applicable to methods that collect microscope field images through image sensors and automatically identify the pore structure of coke and the vitrinite in raw coal using computer software. However, it is not applicable to the identification of single mixed coals or the determination of the proportion of components in blended coals.
