GB/T 8899-2013
ActiveDetermination of maceral group composition and minerals in coal
煤的显微组分组和矿物测定方法
Application Summary AI generated
This standard specifies the microscopic method for determining the maceral group composition (vitrinite, liptinite, inertinite) and mineral content in coal. It is applied in coal geology, mining, and coal preparation industries for resource evaluation, coal rank classification, and predicting coal behavior during combustion, coking, or liquefaction. The method is used by laboratories and quality control facilities to analyze polished coal pellets under reflected light microscopy.
