Optimum design of the open cast mine pit slope is important from both stability and economic point of view. Hence, the aim of the design of an open cast mine is to provide the best possible outline of excavation with respect to safety, ore recovery and financial return [].The most crucial part of the design is to find the optimum slope angle …

The Kolubara Coal Basin is the largest coal-producing area in Serbia. It is administratively comprised of several open-cast mines: Field A, Field B, Field C, Field D, Field E, Field F, Field G ...

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).

This study evaluates the changes in vegetation around Milas-Ö ren open-cast lignite coal mining site, Türkiye, between 1984 and 2023, using Landsat images and Google Earth Engine.

Open cast mining has been practiced in South Africa since the late1970s under near ideal geotechnical conditions. In the past decade, with the exhaustion of the traditional South African coal fields, geotechnical conditions have deteriorated.
