The open pit mines joke was an open pit operation opencast Golpa for the production of brown coal in Bergwitz , north of Gräfenhainichen .
In the Bitterfeld , Wittenberg and Torgau area there is a terminal moraine area known as the Graefenhainichen-Schmiedeberg plateau (see also Dübener Heide ) . Under its Pleistocene cover, layers bearing brown coal are stored. Lignite was extracted from it in several construction fields in the opencast mine.
The exploration began as an opencast mine as early as 1908. He supplied the briquette factory at the train station , which was built in 1905 . Later on, the Zschornewitz power station was also supplied with lignite via a specially built electrically operated mine railway over a distance of approx. 16 km. One of the most modern conveyor bridges in Europe was built here as early as 1932 . The overburden was dumped in the immediate vicinity.
The conveyor bridge and the briquette factory were dismantled in 1945/46 and taken to Ukraine as reparations . After the re-establishment, open-cast mining was resumed in 1948; the briquette factory was not put back into operation.
The open pit mine was finally shut down in 1955. The dump and pit were not renovated until the 1960s. The remaining open pit was flooded through the partial diversion of the Fliethbach and natural access from the groundwater. The Bergwitzsee with about 180 hectares of water was created as a post-mining landscape .
