The United Schleenhain open-cast mine is an open-cast mine operated by the Central German Brown Coal Society (MIBRAG). It consists of the Schleenhain , Peres and Groitzscher Dreieck mining fields , which were operated as independent opencast mines before the merger to form a large open-cast mine.
geography
The opencast mine located in the central part of the Weisse-Elster-Basin about 20 km south of Leipzig consists of the three mining fields Peres, Schleenhain and Groitzscher Dreieck, which functioned as independent opencast mines until 1990. In the area of the opencast mine, which is one of the large deposits in the south of the Leipzig lowland bay, four seams of high quality coal (calorific values 9.7 to 11.1 MJ / kg) with thicknesses of 2 to 30 m have been formed. It is therefore the only one in which all four minable seams of the Weisse Elster Basin are extracted.
The opencast mine is located on the area of the cities of Groitzsch in the west, Neukieritzsch in the east and Regis-Breitingen in the southeast. It is located in the Saxon district of Leipzig .
history
Schleenhain opencast mine (1949–1994)
In 1949, north of Ramsdorf, the Schleenhain opencast mine was opened up in train operation with a 900 mm gauge. The first coal from the Schleenhain opencast mine was mined in 1953. It was first transported by train to a trench bunker and temporarily stored there. From there, the coal was brought to the surface with a more than 1,600-meter-long inclined conveyor system for further train loading. The following transport to the consumers took place by means of a long-distance coal railway. The raw coal and the central spoil were removed in four to five cuts. This was done with the same mine excavators due to the irregular structure of the coal seams. Since 1956 the overburden of the opencast mine has been dumped in the already charred part in the southeast of the area. In 1982, broken mining was introduced to increase the performance of overburden extraction. The overburden was transferred from the overburden train to a conveyor system via two trench bunkers and transported to a type A2Rs-B-8800 conveyor spreader. For the later design and recultivation of the dump surface and the remaining hole of the neighboring disused opencast mine Haselbach (1955–1977), the cultivable soil was transported to the As 1120 type settlers by train. The center spoil was also fed to the As 1600 or 1120 skimmers working on the dump.
The Schleenhain opencast mine initially swiveled clockwise around pivot points 1 and 2 north of Ramsdorf. The "Löschützmühle" belonging to Hagenest was devastated in 1957/58 . 20 people were relocated. Parts of Kleinhermsdorf / Nehmitz with a total of 70 inhabitants were excavated in 1960/61. In 1967/68 the Schleenhain opencast mine reached the eponymous place Schleenhain , whereby its 270 inhabitants were resettled. Part of the Schnauder also had to be relocated through the opencast mine. In 1974 the pivot point was shifted. While this was previously located in the south-west of Heuersdorf south of the opencast mine Schleenhain, the area north of Heuersdorf was now dredged clockwise from pivot point 3. In 1982/83 they reached the town of Droßdorf (300 inhabitants) in the north of the mining area . The last place that had to give way to the Schleenhain opencast mine was Breunsdorf , which was devastated between 1987 and 1994. 450 people were relocated. When the site was demolished, the Saxon State Office for Archeology, Dresden excavated the entire area of the village with funds from the German Research Foundation .
Between 1949 and 1994 the Schleenhain opencast mine produced 325 million tons of coal on an area of 2240 hectares. For this purpose, 1.072 billion cubic meters of overburden was removed. Thus, the ratio of overburden to coal in the Schleenhain mining field is around 3: 1 on average.
United Schleenhain opencast mine (since 1995)
In contrast to most of the other open-cast mines in the Central German and Lusatian lignite district , the Schleenhain open-cast mine was spared from being closed. Up until 1991 the refining sites Deutzen and Regis-Breitingen were mainly supplied, but intensive efforts by politics and business in 1993 ensured the continued purchase of lignite from Schleenhain. With a contract to supply the new Lippendorf power plant until the end of the open-cast mine, coal production was secured until 2040. In 1995, as a result of the privatization of the opencast mines of the Central German District, the Schleenhain opencast mine and the Groitzscher Dreieck and Peres opencast mines, which were suspended in 1991, were merged by MIBRAG mbH to form the United Schleenhain opencast mine with the three mining fields of the same name. After extensive modernization work since 1999, this has been used exclusively to supply coal to the new Lippendorf power plant . According to the current planning permits, the dismantling is to continue until 2040.
Until November 2005, MIBRAG had wrestled for approval to demolish the town of Heuersdorf with its Großhermsdorf district in the south of Leipzig in order to be able to continue operating the United Schleenhain opencast mine. The inhabitants of Heuersdorf ultimately fought against this in vain. In the course of the devastation of the place, the Emmaus Church was moved to Borna .
At Neukieritzsch there was a lookout point in the opencast mine, which was moved to Deutzen in 2012 .
technology
Coal production in the United Schleenhain open-cast mine takes place in belt operation. For this purpose, 2 bucket chain excavators, 6 bucket wheel excavators and 2 spreaders are working in the opencast mine.
