Coal exploration modelling using geostatistics in Jharia coalfield

The Jharia basin is considered as one of the Gondwana outliers in peninsular India. The oval shaped coalfield has an areal extent of about 458 sq. km (Fig. 1) with about 40 km long in east–west direction and about 20 km wide in the north–south direction (Chandra, 1992). The coalfield displays a thick sedimentary sequence of about Abstract. China produced 17.1 billion cubic meters (BCM) of methane sourced from coal seams in 2015, of which 4.43 BCM is from wells drilled from the surface.

Coal mining Prospecting, Exploration, Mining Britannica

Prospecting and exploration. The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been discovered,
