Application of Geo-Informatics for Environmental Health Assessment (EHA) on Iron-Ore Mines area, Noamundi Block, Jharkhand, India

摘要

The impact of mining and mineral extraction activities have very significant role for land, air and water bodies in any operational mines and its surrounding areas. Multispectral satellite data have demonstrated its ability to detect, monitoring of geo-environmental change based on remote sensing applications. The Noamundi iron-mine in the Paschim Singhbhum district of Jharkhand is one of the important mining areas since the eighteenth century. The main iron-ore in this area is hematite. The use of normalized difference vegetation index (NDVI), measures the amount of greenery/ vegetation in the area. At the present time, it has become obligatory to study and analyze the impacts of mining on its surrounding area with the use of remote sensing (RS) and geo-spatial information system (GIS) to generate thematic maps for environmental impact assessment (EIA) over the mining affected area. Therefore, it can be concluded that increase in mining activities is damaging the vegetation, land, and environment. The present study can be useful to identify the degraded area due to mining activity and necessary environmental management plan (EMP) with their societal aspects can be taken up to mitigate the problem.
