Hydrogeology of Indian Coalfields A A Case Study Underground Coal Gasification Project Merta Road Rajasthan analysis of the hydrogeological data of the experimental site, the following conclusions were drawn – the hydrogeological conditions of the experimental site has changed considerably due to extensive water pumping resulting in drawdown in aquifer ‘A’ ( saturated thickness 4 m). No need of dewatering operation in Aquifer ‘A’ Aquifer ‘B’ below Lignite seam is multilayered thick system Advanced dewatering required for Aquifer ‘B’,
