Open pit disk

from Wikipedia, the free encyclopedia

The Platte opencast mine , in Upper Sorbian Šibojska jama , was an open-cast lignite mine that was operated from 1985 to 1996 east of Hoyerswerda in the Lusatian lignite mining district. In 1986/1987 the eponymous town of Scheibe and the expansion of the town of Burg to the north had to give way to him. After the end of the coaling process, the Scheibe See emerged as a post- mining landscape .

geography

The densely wooded previous construction landscape was assigned to the Muskauer Heide or the Oberlausitzer Heide and pond area . Several small ponds, some of which had already silted up, were located south of the opencast mine and had to be drained. The landscape relief was between 114 and 122  m above sea level. HN , through inland dunes locally up to 127  m above sea level. HN .

history

The Ministry of Coal and Energy East Germany decided in March 1980 short-term disruption of the open pit disc, mainly to hedge the coal demand of the gas combine Schwarze Pumpe . The estimated 53 million tons of coal were supposed to secure the coal supply for what was then the largest lignite refining combine in Europe by the end of the 1990s. This required the relocation of the existing infrastructure, and a new river bed had to be built over a length of five kilometers for the Kleine Spree .

The drainage work began as early as 1982 and exploration dredging began in April 1984. In October 1984, dredging began in the 1st cut and in March 1985 in the 2nd and 3rd cut. On November 15, 1985, raw coal mining began.

By parallel degradation, the open pit from east to west developed, whereby a waste tilting to 1987 at the outer tip of the eastern mine Lohsa was made possible. This was followed by internal tilting, with the internal tilting being completely covered with water after flooding. Since 1991, the overburden has been transported to the rehabilitation area of ​​the Spreetal opencast mine on a seven-kilometer conveyor system .

On October 16, 1995, the 1st cut and on August 9, 1996 the 2nd and 3rd cut were phased out. The overburden operation thus reached its end position. Coal production was stopped on November 25, 1996 after eleven years and complete coal depletion. During the period, 225.2 million cubic meters of overburden were moved and 52.58 million tons of raw brown coal were extracted. The open pit took up 758.1 hectares for mining purposes.

The open pit mine was operated by BKW Welzow and its successor company LAUBAG . On July 1, 1994, it was taken over by LBV, which merged in 1996 to form LMBV . She rehabilitated the remaining open pit after the mining operations ended. The most striking remnant is the Scheibesee , which covered the inner dump in 2010.
