Coal industry is very important for developing countries like India. India has a vast reservoir of coal in the world, come on the world’s fifth-largest coal proved reserves including Lignites (Approx. 100 billion tonnes). Coal is a mixture of heterogeneous rock materials, including organic as well as inorganic contents in it, that’s why the most advanced technology is used for its characterisation to meet as per the demand in thermal industries. In the thermal industry of India, coal grade is analysed by the Proximate analysis & Gross Calorific Value (GCV). The investigation area is Sohagpur coalfield of Gondwana group. Coal bearing formation of Sohagpur coalfield is Barakar formation. The average value of moisture% is 2.8, Ash% is 15.12, Volatile matter% is 26.71 & Fixed carbon% is 55.32 in coal samples. Relation of ash% in coal & its grade is inversely proportional to each other, that’s why ash content should be lower for producer & consumers also. According to the joint work of XRD & FTIR, we know about the characteristics minerals, organic group & bonding present in coal. This study will unveil the reason of grade variation in coals, which will be helpful in thermal industries. The inorganic content (Minerals) & sulphur amount in coal tells us the allocthonous deposition in Mahanadi Basin of the Gondwana group. In this paper we are trying to know the reason in grade variation of coal, these studies can unveil to very minute details present in coal for gradevariation.
