The open pit coal mine topography is mostly rugged and uneven. In general, it is a few kilometers wide and more than 50 m deep. In the case of deep open pits, the depth may be as high as 300-400 meters. The complexity arises due to the presence of overburden dumps, construction of access roads and blasting activities.
Along with changes in land-use, open cast coal mining also changes the topography along with the drainage pattern of the region. It was observed that majority of the increase in opencast mining area (53%) and built-up area (85%) took place between 2003 and 2010 for the present study area (BCCL Annual Report 2013–2014).
