“…4a, b). Similar observations are made elsewhere (Ryan 1992;Pophare et al 2008;Karmakar et al 2013;Panwar et al 2017;Kumar et al 2015). It can be concluded from coal properties linear relationships that coal is inferred to have good enough methane gas in its seams.…”

The increasing demand for cleaner source of energy forces India to explore various energy sources, and in this process, coal bed methane gas attracts lot of attention for its favourable characteristics including abundance of coal, clean gas, mitigation of greenhouse gases, reduction in hazard in mines, etc. However, the challenge faced during exploration and production varies from depth of seam, heterogeneity in coal characteristics, rank, sorption capacity, saturation, etc. So the detail analysis of various properties is important for economical extraction of gas. The present paper investigates coal properties and their influence on coal bed methane potentiality. Samples from core wells have been analysed in laboratory using proximate and ultimate analyser. Linear correlations between coal constituents and vitrinite reflectance as well as sorption capacity of coal have been established statistically. Mutual relations among proximate parameters are developed.

“…In past studies, gas content has been used as a proxy to the amount of methane that be mitigated from such mines ( Kholod et al., 2020 ). Although our analysis did not particularly evaluate the gas content of the 108 mines, previous analyses have shown that the gas content may be ∼60% in an average gassy coal mine ( Singh and Hajra, 2018 ; Panwar et al., 2017 ). As such, we have assumed that 60% of methane emissions may be mitigated from Degree-II and Degree-III mines in the form of CMM.…”

Methane content in a coal seam is a necessary parameter for evaluating coal bed gas, and it poses an environmental risk to underground coal mining activities. Keeping in pace with comprehensive studies of coal bed gas, 12 coal samples were selected from the Sitarampur block of Raniganj Coalfield for analysis. The Petrographic examination illustrated that significant values of reactive macerals present in samples demonstrate that organic matter is dominated by the prominent source of aromatic hydrocarbons with a minor proportion of aliphatic hydrocarbon, which falls in the region of (Type III) kerogen, confirms the suitability for the potential of hydrocarbon generation. “A” factor (aliphatic/aromatic bands) and “C” factor (carbonyl/carboxyl bands) value concluded that the sample has the lowest aromaticity and the highest hydrocarbon-generating potential, which was also validated by the Van Krevelen diagram. The Van Krevelen diagram plots between the H/C and O/C ratio indicate that coal samples lie in the type III kerogen, and bituminous coal (gas prone zone) is present in the block, which is confirmed by the cross-plot between desorbed and total gas (cc/g). The in situ gas content values are high enough to produce methane from coal beds. The overall study concludes that the Sitarampur block from Raniganj Coalfield is suitable for hydrocarbon generation and extraction.
