Remote sensing (RS) and Geographic Information System (GIS) is a powerful tool for managing and planning the mining activities and has an advantage of synoptic view, temporal capability and can observe the inaccessible areas. Open cast mining activities has direct impact on earth surface which can be studied and quantified using remote sensing technology. In the present paper, we examined the areal expansion of the coal mines and their impact on the surrounding area of Wani using RS and GIS technique. The LANDSAT, IRS and High resolution satellite data of Google, having resolution of 30m, 23m, and 50cm respectively have been used. Changes in the crop land due to mining activities were calculated using heads-up interpretation of satellite data using ArcGIS software. Present study has shown that in Wani area crop land has decreased by 6.46% in the span of 26 years following the expansion of mining activities in the area.
