Sampling of Coal: Sampling of coal is a crucial process used to determine the characteristics and quality of coal. It involves collecting representative samples from different parts of a coal deposit, shipment, or stockpile to analyze its properties. The collected data helps in assessing the coal's suitability for specific applications, determining its value, and ensuring compliance with various quality standards. The purpose of collecting and preparing a sample of Coal is to provide a test sample which, when analysed, will provide test results representative of the lot sampled. This helps ensure an accurate characterization of the coal from which the sample is taken. Proper sampling and sample preparation are critical for accurate analysis. Statistically, about 80% of the total variances involved at the different stages of sample collection, preparation and analysis come from errors during its collection. There are two criteria that must be followed when sampling to ensure t...
