Introduction to coal sampling

Introduction. All testing and analysis results that define the quality of a quantity of coal are obtained from a sample. It could be a 60,000 tonne shipment, a day's production, a 10,000 tonne train load, a 100,000 tonne stockpile, or any other quantity of interest. Sampling is an unavoidable feature of the coal industry.
