Sedlitz opencast mine

from Wikipedia, the free encyclopedia

The Sedlitz open-cast mine was an open-cast lignite mine in the Lusatian lignite district, which was operated in the Cottbus district from 1921 to 1980 . It was in the Senftenberg district . In the course of recultivation , the Sedlitz Lake is being created as a post-mining landscape .

geography

The Sedlitz opencast mine was located in Niederlausitz in the so-called Niederlausitz lignite area. Lignite was mined from the Lausitz lower seam (2nd Lusatian seam horizon), which was cut into a large number of fields by the Pleistocene erosion of the ice age meltwater.

The open pit was northeast of the city of Senftenberg and southeast of Großräschen . In the west it was limited by the Grossenhain – Cottbus railway line and today's federal highway 169 .

history

In 1921, the drainage work began for the opencast mine, which was opened up in 1926 as the Ilse-Ost mine by Ilse Bergbau AG . Coal production in the main field began in 1928, the north and south side fields continued to be opened up. In 1931 the conveyor bridge F35, one of the largest overburden conveyor bridges in Germany, was put into operation. The conveyor bridge as well as the bucket chain excavator and the bucket wheel excavator were dismantled in 1945 as reparation payments for the Soviet Union.

Coal production began again in 1947. The Ilse-Ost open-cast mine was renamed Tatkraft open-cast mine . It developed in train operations to the north and south field Sedlitz. This resulted in the Sorno pivot point for the Sedlitz main field by 1960. From 1960 to 1978 a conveyor bridge association worked clockwise around the Sorno pivot point. For this purpose, conveyor bridge F34 number 23 was put into operation in 1960.

In the secondary fields south and north, coal production was discontinued in 1961 and 1963. Coal mining began in the Sedlitz bridge field in 1963. On March 18, 1963, an accident occurred when the dump jib of the conveyor bridge hit the dump and was severely deformed. For this reason, raw coal production was partially stopped. On May 1, 1963, the conveyor bridge went back into operation.

On March 1, 1978, the conveyor bridge near the village of Lieske was brought into its final position. In 1980, work in the Sedlitz opencast mine was stopped.

Conveyor bridge association

The conveyor bridge F34, manufactured by VEB Bagger-, Förderbrücken- und Gerätebau (BFG) Lauchhammer , was built from March 10th to August 11th, 1960. It had a span of 180 meters and a 75 meter long tailings jib. A bucket chain excavator 640 Ds 1120 was connected to the bridge. Another single- chain excavator of the type 622 Ds 1120, which was used in the north field from 1957 to 1962, was relocated in August 1962 for use with conveyor bridges. In the two-way excavator operation, up to 65,000 cubic meters of overburden could be moved daily.

The bucket chain excavator 640 was replaced by the bridge association in October 1977 and moved to Hörlitz. The conveyor network then worked in single-excavator operation. On February 19, 1978, the conveyor bridge was shut down. On March 10, 1978 it was handed over to the Bitterfeld lignite combine, which dismantled the bridge in order to rebuild it in the Delitzsch-Südwest opencast mine . Here the bridge with the newly built bucket chain excavator 1297 went back into operation on December 21, 1979.

Brown coal

The extracted lignite was supplied to the surrounding briquette factories and power plants in Senftenberg, Großräschen, Lauta and Schwarze Pumpe .

A total of 267 million tons of raw brown coal was mined.

Site and land use

The open pit took up an area of ​​2639 hectares. 975 million cubic meters of overburden were moved. The villages of Rosendorf in 1971 and Sorno in 1972 were devastated and 340 residents were resettled. Sedlitz was demolished from 1962 to 1963, and Lieske was demolished from 1962 to 1967 with 35 resettled residents.

Redevelopment and tourist use

Emerging Lake Sedlitz

The Lausitzer und Mitteldeutsche Bergbau-Verwaltungsgesellschaft (LMBV) rehabilitated the area of ​​the former opencast mine. The tipped embankments were flattened, former landfills removed or secured, infrastructure created and former open-cast mines dismantled. The open pit water was also raised and cleaned.

The Sedlitz Lake is created as a post-mining landscape by flooding the remaining hole . It is to be connected to the Großräschener See via the Sorno Canal and to the Partwitzer See via the Rosendorfer Canal . These two lakes were also created from former open-cast mines, the Großräschener See from the Meuro open-cast mine and the Partwitzer See from the Skado open-cast mine . The renovation work on Lake Sedlitz should be completed by the end of 2019.
