Coal accounts for 55% of the country's energy needs. Coal is of four main types and each type of coal has different levels of organic content, ash content, and moisture. These cause a variation in the calorific value from different mines or parts of any mine. Besides, the variations also impact the environment differently. Thus analysis of coal provides information on its best usage. In addition, the calorific value and other parameters determine the monetary value of the coal. Therefore, coal is sampled and tested. Coal sampling is done to have a reasonably accurate representation of the entire lot. Handling, storing and transporting coal samples is essential and must preserve the sample's integrity. Variations in coal quality have a significant impact on its commercial value and do contribute to corruption. Independent coal sampling and analysis is the accepted method for sellers and buyers to avoid disputes.
