The lignite opencast mine Reichwalde ( Upper Sorbian Rychwałdska brunicowa jama ) is an opencast mine of Lausitz Energie Bergbau AG in the southeast of the Lausitz lignite mining area in Saxony and was named after the place Reichwalde in the municipality of Boxberg / OL ( district of Görlitz ). The opencast mine was opened in the 1980s and served exclusively to supply the nearby Boxberg power station .
geography
The previous mining area of the opencast mine extends over an area of 5 by 3 kilometers between the diverted course of the Weißen Schöps and the Oberlausitz military training area in the north, the municipality of Rietschen in the east, the village of Reichwalde in the south and Kringelsdorf and Boxberg in the west.
The open-cast mining area is now part of the communities of Rietschen and Boxberg.
Brown coal
The lignite is stored in the Reichwalde opencast mine up to 85 meters below the surface. The seam is nine to twelve meters thick. The reserves amount to 366 million tons of brown coal.
history
In 1980, the development of the easternmost opencast mine in the Lusatian district began. Field drainage began in a more densely populated area south of the Nochten opencast mine, which has been mining since 1973 . 1987 saw the first lignite mining in Reichwalde.
Funding was deferred in 1999 for reasons of profitability. In 2007, work began on recommissioning, which, according to Vattenfall, cost around 350 million euros. Among other things, all conveyor equipment was renewed, including the F60 conveyor bridge . Since the beginning of April 2010, excavated material has been moved again in Reichwalde in order to create the necessary coal exposure for mining operations. In December 2010, lignite production was resumed, and mining was planned to take place by around 2045. Due to the coal phase-out in Germany , which should be completed by 2038, it can be assumed that production will end sooner.
On April 25, 2018, the exposed coal seam caught fire. The fire quickly reached an extent of up to 2000 × 100 meters and burned for several days, as the fire had been kindled again and again by the prevailing wind. As of April 29, it had not yet been deleted. The coal conveyor belt over a length of several hundred meters and several fire engines were damaged while fighting the fire. As a measure against the fire (as of April 29, 2018 00:21), the operator LEAG is filling the burning area with the help of the overburden conveyor bridge. It is still unclear why this fire could occur. Coal production resumed on May 25, 2018.
Site and land use
The entire municipality of Wunscha ( Upper Sorbian Wunšow ) with its districts Publick (Publik) , Reichwalder Schäferei (Mosty) and Schadendorf (Pakosnica) had to give way to the Reichwalde opencast mine in the 1980s . A total of 173 residents were resettled here. In addition, the natural course of the Weißen Schöps, the confluence with the Schwarzen Schöps and large parts of the Reichwalder ponds were dredged over and destroyed. The river itself was diverted and now passed the mine as a canal on its northern edge. In order to be able to continue the open-cast mine in a north-easterly direction, the White Schöps was relocated again until 2014, so that it now flows south of the open-cast mine into the Black Schöps and flows into it shortly before Reichwalde.
For the expansion of the opencast mine in an easterly direction, the villages of Mocholz , Viereichen , Zweibrück and Altliebel , which had been in the brown coal reserve for years , were evacuated between 1993 and 1995 and then dismantled. However, the temporary shutdown of operations in 1999 meant that the places had not been dredged until 2013, but could still be found as devastation. A large part of the population had left the settlements before the evacuation. The ponds near Hammerstadt are also affected by the continuation of operations in Reichwalde .
All evacuated or excavated villages belonged to the central Sorbian settlement area and in the 1880s still had a share of over 90% Sorbian-speaking inhabitants.
According to the lignite plan, a large part of the Upper Lusatia military training area and the Berlin – Görlitz railway line will also be affected in the long term by the expansion of the northern open pit from 2010 . In the latter case, the ten-kilometer section between Weißwasser and Rietschen is to be relocated parallel to federal highway 115 to the east by 2026. In the future, the open-cast mining area will extend to Hammerstadt and the B 115. This would quadruple its current size.
