The Saar mine was a hard coal mine with its main location (cableway and coal extraction and processing) in Ensdorf and another location (cableway) in Lebach-Falscheid in the Saarlouis district . It was the last active mine of RAG Deutsche Steinkohle AG in Saarland . It was created on January 1, 2004 by merging the two mines Warndt / Luisenthal and Ensdorf to form an organizational unit with still two production sites. On June 17, 2005, hard coal mining was stopped at the Warndt / Luisenthal site .
After a rock attack in February 2008, there was a heated public discussion about the future of Saar mining, also against the background of the general end of mining for German hard coal. The mine operators and politicians decided to discontinue production in the Saar mine at the end of June 2012.
history
Coal mining in the Ensdorf / Schwalbach area is documented for 1730; At that time, farmers extracted coal from outgoing seams in open-cast mining . In 1815 the Griesborn and Schwalbach mines came into the possession of the Prussian mining treasury , who systematically exploited the coal seams: the mining administration had day-care facilities built and in 1826 the first day shaft (Schwalbach shaft) was sunk in the Prussian part of the Saar area . Saarland shipping initially played an important role in the sale of coal . For this purpose, the Ensdorfer tunnel, a two-kilometer long transport tunnel to the banks of the Saar, was created in 1842 . In 1857 the Griesborn shaft was sunk; In 1861 it was connected to the Saarbrücken – Trier railway line . As a result, production and sales increased by leaps and bounds, so that more shafts were sunk: Ensdorfer Schacht (1866), Ostschacht (1867, later renamed Ney-Schacht after the Saarland-French Marshal Michel Ney ), Knausholzschacht (1873) and Wilhelmschacht (1877) . In 1910 the Ensdorfer tunnel was closed; In 1913, the Saar shaft (later renamed Duhamel shaft after Jean Baptist Duhamel ) was excavated as the new main shaft . From 1936 the Elm shaft was sunk. After heavy damage in World War II, which was promoting resumed 1946th In 1957 the merged Duhamel and Griesborn facilities became the Ensdorf mine .
In the 1970s, the Duhamel ( depth : 868 meters), Ney (651 meters), Elm (281 meters) and Dilsburg (632 meters) shafts were in operation. The main extraction level was at a depth of 608 meters; more than half of the mined coal seams had a thickness of about three meters. By 1976 all struts were converted to shield support . Due to the mining in a large area with only a few seams, there were over 100 kilometers of open stretches in the 1970s . Between 1975 and 1978, the Barbarastollen, a 3,500 meter long inclined shaft , was built, which overcomes a height difference of 610 meters. The Barbarastollen was used for extraction from the northern field; for this purpose it was equipped with a conveyor system that could transport 1,400 tons per hour. The north shaft was also sunk in the 1970s, which was sunk further to 1751 meters by January 13, 1997 and connected to the 24th level (1712 m depth). The north shaft can still be navigated to a depth of almost 1400 meters using an auxiliary drive system. So it is still the deepest and next to the Reden IV / V shafts and the Duhamel shaft one of the last still open shafts on the Saar.
The dump of the Saar mine near the Duhamel shaft in Ensdorf is colloquially known as Mont Duhamel or Monte Schlacko . With an approximate height of 140 meters, it is the highest in the Saarland. It has been open to the public since 2004 and is used by paragliders, among others. In 2005, the art project Kunst auf der Halde was exhibited on it, but only a few of these were to be permanent exhibits. This includes the 15-meter-high heavenly ladder , which, however, was sawed off by strangers on the night of August 25, 2011. After the end of the Saar mining industry in 2012, the 30-meter-high Saar polygon , an accessible steel sculpture , was built on the heap and opened in September 2016.
With almost 4,000 employees, the Saar mine achieved a turnover of around 517 million euros in 2006. In 2007, the exploitable was promoting around 3.5 million tons of steam coal . The daily output averaged around 14,400 tons.
The mine has hit the headlines in recent years due to mining-related earth tremors. After a severe earth tremor with a magnitude of 4.0 on the Richter scale on February 23, 2008, the Saarland state government ordered a mining stop for the Saar mine. Around 3,600 miners were initially released from work by RAG Aktiengesellschaft.
In response, the supervisory board of RAG Deutsche Steinkohle decided on March 14, 2008 to end production in the Saar mine by 2012. Until then, operations should continue in a reduced form. The mining in the Primsmulde Süd field , which was probably the trigger for the tremors on February 23, 2008, and in the Schwalbach seam should no longer be started. Instead, hard coal should only be mined in the Grangeleisen and Wahlschied seams. This reduced the output to a third of the previous one. 3,000 jobs were thus retained for the next few years. In the earthquake year 2008, only around 1 million tons of hard coal was mined, which corresponded to a turnover of more than 300 million euros.
At the end of June 2012, hard coal production in the Saar mine ended and thus after several centuries the hard coal production in Saarland. Some of the employees will take over the underground dismantling of the systems and the securing of the shafts. Additional employees who are too young to take early retirement will be transferred to the remaining RAG locations.
