Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, [1] is a surface mining technique that extracts rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin. In contrast, deeper mineral ...

The open-pit mine was put into operation in 1978. Every year, about 0.3 cubic kilometres are moved, so that coal and soil with a volume of about 18.6 km 3 will be mined by the time the coal runs out in 2040. By April 2009, the overburden was being transported by conveyor belt to refill the now-exhausted Bergheim mine.
