Application Summary AI generated
This standard specifies the methods for collecting coal samples directly from coal seams, including the procedures for channel sampling and drill-hole sampling. It is applied in the mining industry for geological exploration, coal quality assessment, and resource evaluation to determine the physical and chemical properties of in-situ coal. The standard ensures representative sampling for accurate analysis of seam characteristics, such as ash content and calorific value, before extraction or processing.
