ActiveMacrolithotype classification for brown coals and lignites
褐煤宏观岩石类型分类
Application Summary AI generated
This standard provides a systematic classification method for the macroscopic rock types of brown coals and lignites, based on physical characteristics like color, luster, and fracture. It is applied in the coal mining and geological exploration industries to standardize field descriptions, resource assessments, and quality evaluations of low-rank coal deposits. The classification aids in correlating coal seam properties with utilization potential, such as for power generation or gasification.
