The Klettwitz opencast mine was an opencast lignite mine in the Lausitz lignite mining area in what is now southern Brandenburg , which existed from 1949 to 1991. It was named after the community of Klettwitz in what is now the Oberspreewald-Lausitz district.
history
The Klettwitz opencast mine was opened in 1949. It mainly served to supply the briquette factories in Klettwitz, Schwarzheide-Ost , Hörlitz , Brieske , Lauchhammer and Plessa . Since the open pit Schwarzheide ( "Friedlander") ceased its operations, the digestion of the carried out of the mine Klettwitz in the immediate vicinity pit Anna-south -west of the local situation of Schipkau whose overburden conveyor bridge type F 25 as reparations dismantled in 1947 and the Soviet Union had been spent . This made it easier to move the Schwarzheider overburden conveyor bridge, type 45, that was now vacated in the new mining field in 1954. However, mining operations in Klettwitz had already started two years earlier.
The F 25 went into operation in the Klettwitz opencast mine on July 1, 1954. In the following year, a pre-cut operation was set up, for which up to four bucket wheel excavators were in use until 1958 . Lignite mining came to a standstill in the winter of 1958. A slide in the bridge dump caused the F 25 to collapse on February 9, 1958. Before it was destroyed , this conveyor bridge had moved 92.8 million m³ of overburden in the Klettwitz opencast mine in the four years.
In October 1958, another overburden conveyor bridge, the F 20, went into operation. This had already been in operation in the Wildgrube and Tröbitz opencast mines, but was nowhere near the capacity of the F 45. While the F 25 had an annual maximum output of 28.2 million m³ in 1956, the F 20 achieved its highest output in 1959 with 6.6 million m³. They were taken out of operation a few years later. In 1964 it was dismantled by blasting .
Since the thickness of the overburden in the mining field was now over 100 meters, the follow-up bridge was redesigned specifically for use in Klettwitz. The F 45 went into operation in Klettwitz in 1962. There was also a pre-cut operation here. Thanks to continuous modernization and reconstruction of the technology on the bridge itself and in the surrounding area, it was able to continue to operate until 1990. In that year it had reached its planned final position near the local area of Kostebrau and as a result ceased operations.
The mining of the remaining coal in the Klettwitz opencast mine continued until June 1991. And while the F 45 was blown up in October 1991 and finally scrapped, most of the remaining large-scale technology was implemented in the Klettwitz-Nord opencast mine, which was opened in 1988 , where a conveyor bridge of the type F 60 should be used.
By the end of the open pit in 1991, almost 5,200 hectares of land had been dredged over and 362 million tons of lignite extracted. The three conveyor bridges in use alone moved 1,324 million m³ of overburden.
Among other things, he fell victim to part of the local situation of Klettwitz, which was devastated in 1963/1964. 1200 inhabitants were resettled, 200 of them within the village. In addition, the Kostebrauer districts Römerkeller (1980) and Wischgrund (1983) were devastated.
