Abstract

The open cast mining has, in some places, extended below the groundwater table. impact of mining may affect availability of groundwater, and this has become a matter of concern because villages in that region (near open cast mines_ suffer from water scarcity during dry periods. Exploitation of an enormous amount of ore may result in groundwater depletion. However, these effects are dependent mainly on the geological formations in the region and mining method. In some places, groundwater table occurs at shallow depth from the surface and some places underlying strata are impervious clay layers, which may be above groundwater table. In most places, clay layers exist above groundwater table. Due to presence of impervious clay layers above the groundwater table, extraction of ores will most likely not affect surrounding hydrological regime of those areas. This paper aims to highlight the significance of Ground Penetrating Radar (GPR) Survey prior to excavation in areas where impervious clay layers occur as underlying strata. GPR will be very helpful to check groundwater depletion in open cast mines indirectly after exploring the subsurface. geological scenario. Hydrological regime of the mining areas will be saved with the help of GPR by distinguishing between groundwater and clay.
