In these three mining areas, lignite is exclusively extracted at opencast mines. In 2018, a total of 880 million cubic metres of overburden were moved during mining an average overburdentocoal ratio of cubic metres per tonne.
Opencast mining is also known as openput mining, opencut mining, surface mining and also as strip mining, the later term being commonly used in the for opencast mining of coal.

The opencast coal mining technique is used in areas were the coal reserves are scattered in shallow and thin seams and cannot be extracted by deep mining methods (Beynon et al., 2000). The opencast process starts with exploration activities to identify where there are deposits of coal
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity.
