Estimation of gross calorific value of coal: A literature …
was found that the ultimate analysis of coal is the best predictor. Begum, Chakravarty, and Das (2019) used proximate data and coal's spectral reflectance data to estimate the GCV of coal. The models were created using the MLR approach. Ash, moisture, and volatile matter content are the proximate analysis of coal results.

Along with moisture and ash contents, the percentage of volatile matter in a coal sample is needed to calculate the fixed-carbon content of a coal. Many electric utilities prefer coals within a narrow range of volatile matter (25 to 35 percent) for optimal flame stability in the boiler (Thomas, 1992).

What is the difference between ARB and GAR in Coal Analysis?
What does ARB stand for in coal specification? ARB stands for "As-Received Basis" in coal specification. This means that the coal sample is analyzed without any alteration, including its moisture content. ARB is often used to evaluate the energy content and other properties of coal as it is actually delivered.
