褐煤显微组分分类
Application Summary AI generated
This standard provides a systematic classification system for the organic microscopic components (macerals) found in brown coals and lignites, defining specific groups and sub-groups based on their optical properties and morphology. It is applied in coal geology, mining, and coal preparation industries for resource evaluation, quality assessment, and utilization planning, particularly in contexts such as coal petrology analysis, combustion behavior prediction, and coke-making feedstock characterization.
