This coal mine was put into operation in 1977. Both the architectural style and the interior of Bergwerk Blumenthal clearly date from the 1970s. The coal company was taken over several times by other companies before finally being decommissioned in 1999. The mine shaft itself is six by six meters wide and extends over 1,100 meters underground. Together with the nearby second mine shaft of the same company, 3 million tons of coal were extracted annually. In 2015, the shaft was filled with 37,000 m³ of concrete.
