The Warndt mine was a hard coal mine near the Großrosseln district of Karlsbrunn , which was built by Saarbergwerke AG. It was the youngest mine in the Saar district.
Location and geography
The mine is located in the middle of the Warndt on the L276 between the districts of Karlsbrunn and Dorf im Warndt in the municipality of Großrosseln. Here are the seams of the Merlebacher Saddle in the Saar coal basin and the Lorraine coal basin. The Warndt mine had minable coal reserves of around 190 million tons, calculated down to a depth of −1100 meters above sea level. The thickness of the seams varied between one and six meters.
history
As early as 1938, a large mine was planned in the Warndt to extract hard coal. But the Second World War prevented the start of mining. With the Saar Treaty of 1956, the construction and operation of a mine in the Warndtkohlengebiet was allowed. The mining fields leased by France were returned to Germany, including the St. Charles-Vuillemin field (Großrosseln-Emmersweiler field) with the St. Charles shaft.
Work on the new mine began on 14 March 1958, the Warndtschacht was in the same year sunk . The concrete tower hoisting system was built in 1960/61 by the Mannheim branch of Philipp Holzmann AG, and in 1963 the pit began to produce. The shafts of the Velsen mine were taken over as external shafts in 1964. Fatty coal from the Sulzbach strata was mined , which was used as coking coal to supply the Saarland steel industry.
The Warndt tunnel was excavated from 1963 to 1965 with a cross-section of 13 m² and a length of 2100 m. In 1964, the Warndt-St. Charles hit. In 1981 another tunnel was excavated, which led with a length of 2550 m to the former Ludweiler shaft. In 1998, a 2500 m long transport tunnel was excavated, which was supposed to transport the tailings that were produced in the Warndt processing plant when the coal was washed to Merlebach , France .
In 1978, an additional agreement to the contract of 1957 allowed the French coal mines to continue to mine fat coal in an area of the Merlebach field that was difficult to access for the Warndt mine. For this purpose, rent was paid for each ton of usable production.
The Saarbergwerke's supervisory board resolution to merge the Warndt and Luisenthal mines had already taken place in 1981 . In 1988 both pits were combined and Verbund West was created. On July 18, 1994, the Warndt / Luisenthal composite line broke through. The route is around 3.2 kilometers long and runs at a depth of 1,100 meters. The first mining of Luisenthal coal in Warndt took place in November of the same year.
In September 2003, for economic reasons, RAG announced the end of coal mining in the Warndt mine for the beginning of 2006. On January 1, 2004, the two remaining mines Warndt / Luisenthal and Ensdorf were merged into an organizational unit with two production sites ("Saar mine") . On June 17, 2005, coal production in the Warndt was stopped, and on January 1, 2006, “Verbund West” was completely shut down. The warning shaft was then filled with concrete.
Shafts
The main shaft was the Warndt shaft (−1160 m above sea level) in Dorf im Warndt, which also served as a cable car and material shaft. The 931 m deep Lauterbach shaft was an extending weather shaft. The devil's scaffolding from 1979 still stands here. Gustav 2 shaft of the former Velsen mine in Großrosseln was used as a weather and cableway shaft. The depth is -1095 m. The truss frame is from 1915.
With the return of the St. Charles-Vuillemin mining field, located on German territory but leased to France, on January 1, 1962, the Warndt mine received the St. Charles shaft, which was named St. Charles IV shaft from 1949 to 1953 by the Lorraine mine operator Houllier du Bassin de Lorraine (HBL) had been sunk on Großrosseln district.
Factory settlement
A new district, the so-called residential town, was built as a factory settlement for the Warndt mine workforce in Überherrn, about 20 km away .
Architecture of the day facilities
In terms of architectural appearance, the Wanrdt mine differs from the other Saarland mines through its modern appearance, as it was the youngest mine in Saarland and was thus based on structures that had not grown. When planning, value was placed on creating a clear and self-contained system with the possibility of later operational and technical expansion. The architectural design was given a high priority. The arrangement of the open-cast structures was also determined by specific factors such as the location of the shaft, the terrain and the routing of the railroad siding “Großrosseln – Warndtschacht” as part of the Rosseltalbahn .
At the entrance to the mine there is a 65 kV open-air switchgear that supplied the mine with electricity. In the center of the system is the reinforced concrete headframe, visible from afar, with a box-shaped disc structure and a height of 69.70 m. The access was past a porter's house with a coffee kitchen, switchboard and office space. Clothes lifts were installed in the wash house for around 3,900 miners. A two-storey connecting corridor led to the colliery house with the colliery hall and operations offices. On the first floor, a closed bridge led to the Lampenkaue and on to the winding tower. The over 100 m long magazine building was built as a flat building and has covered loading ramps on both long sides. Finally, the workshop building was erected to the northwest next to the winding tower in the longitudinal axis of the magazine. All buildings are made of reinforced concrete frame construction and faced with Birkenfeld clinker. The huge building with sifting and coal washing plant was located above the mine station and has since been demolished.
The Institute for Regional Studies in Saarland rates the preserved buildings as "important and valuable technical evidence of the era around 1960 [...] which are of particular importance for the Saarland. In addition to this rather regional importance, the Warndt mine also joins the ranks of the few completely new mining facilities in the Federal Republic of Germany at the national level. In this respect, the Warndt mine owns an important building unit that documents the economic and technical development in mining in a particularly impressive way. "
The preserved daytime facilities of the Warndt mine and the St. Charles mine are listed as historical monuments. The system was the first in Saarland to have a vessel conveyor and, due to its modern technical standard, is an example of the development of mining in the post-war period. As the “last uniformly designed and unchanged large mine of its time in Germany”, it is of particular importance.
Current usage
Large parts of the daytime facilities have been preserved. Only the coal preparation, the mine station and the tracks were demolished or removed. Parts of the daytime facilities are used by commercial operations. A solar power plant was built in the area of the former track systems, the mine station and the coal store . In 2009/10, the SaarForst regional company built a biomass cogeneration plant . SaarForst also operates the central fuel yard there.
