The Cottbus-Nord opencast mine was an open-cast lignite mine in the Lusatian lignite district , which was last operated by Vattenfall Europe Mining AG and is now owned by Lausitz Energie Bergbau AG . The larger part is located in the area of the city of Cottbus , a smaller part touches the Spree-Neisse district . Coal production started in 1981 and stopped on December 23, 2015.
Demolitions
Since the opening of the opencast mine in the north of Cottbus in 1978 (exploratory dredging), seven locations were demolished and the Lakoma pond landscape cleared up until 2010: Dissenchen (Dešank; was only recorded during the apron clearance), Groß Lieskow (Liškow), Klein Lieskow (Liškowk) , Lakoma (Łakoma), Merzdorf (Žylowk), Schlichow (Šlichow; large parts of the place are still standing) and Tranitz (Tšawnica). A total of 906 residents had to be resettled.
Reuse
After the end of mining, the post- mining landscape is to be recultivated . Small areas are planned for forestry and the flooding of large areas. With the future Cottbus Baltic Sea, the largest lake in the Lausitz open-cast mine area is to be created.
On April 12, 2019, Prime Minister Dietmar Woidke , Holger Kelch (City of Cottbus), Angelika Seidemann ( LBGR ), Harald Altekrüger (Spree-Neisse district) and the two LEAG board members Helmar Rendez and Uwe Grosser opened the lock at the intake structure with a symbolic push of a button Lakoma, to fill the future lake with water from the Spree. The process will not end until 2025.
technology
In the Cottbus-Nord opencast mine, the overburden has been removed since 1983 with the help of two bucket chain excavators that are connected to an F34 overburden conveyor bridge . The overburden was removed via the conveyor bridge and tipped on the dump side. From 1985 to 1991 a second overburden conveyor bridge of the type F34 was in use in combination with two bucket chain excavators. The second bridge was blown up in 1995. As part of the cessation of coal production at the end of 2015, the overburden conveyor bridge reached its final position in August 2015. On March 3, 2016 the last remaining overburden conveyor bridge of the type F34 was blown up. A pre-cut operation was also in use until 1995. The raw lignite was most recently extracted by two bucket chain and bucket wheel excavators and loaded directly into trains. The Cottbus-Nord opencast mine was the last lignite opencast mine in Germany with direct train loading. Coal production was stopped on December 23, 2015 with the last coal train to the Jänschwalde power plant .
