The United Hörder coal mine was a colliery association in the area of ​​what is now Dortmund 's Brackel and Asseln districts . The facilities belonged to the Hörder Bergwerks- und Hütten-Verein .


In order to make itself as independent as possible of the market conditions when purchasing fuel, the Hörder Bergwerks- und Hütten-Verein acquired a number of mine fields at Brackel and Asseln from 1854 , which were consolidated under the name Hörder Kohlenwerk in 1859 .

Immediately after the acquisition, two were in Brackel civil engineering bays for the promotion and the dewatering drilled . The mine was later named Schleswig . At a depth of 197 m, coal mining could begin in 1859. In 1860 ropeway was set up in the Schleswig I / II shafts . Initially, the coal was only shipped to the Hermannshütte , in later years it was also used in the Hörder Verein's blast furnace.

Hörder coal mine Schleswig shaft

Because of the increasing demand, a new shaft was sunk in Asseln from 1874. In 1877 mining began on the Holstein I shaft , above which an iron headframe was erected in 1892 . Both mines were expanded further and its deepest sole (m Schleswig at a depth of 540 Holstein 510 m) through a 1.8 km long straightening path connected. In 1913, the Hörder coal works achieved the highest annual output with 627,581 t .

On September 16, 1924, when the mining dump was being removed from the Schleswig colliery, a gas explosion occurred in which eleven workers were killed. The closure of the Schleswig colliery (July 15, 1925) and the Holstein colliery (August 1, 1928) meant the end of the United Hörder coal works.

Current condition

The entrance portal, the brine bathhouse (both on Neuhammerweg) and the “Am Knie” mining officials' settlement are still preserved today from the Schleswig colliery. The former mining dump of the Schleswig shaft was later used to store slag from the Phoenix-West blast furnace operated by Hoesch AG and was in operation as an industrial landfill until the end of 2007. Since then, the landmark, which is clearly visible from the south, has been developed into a leisure landscape with bike and footpaths in a project initiated by the current owner, ThyssenKruppSteel, by 2011. The gatehouse (Donnerstrasse / corner of Briefsweg) and the Holstein colony are still preserved from the Holstein colliery . The former horse stable, the smithy and a transformer house are still on the mine site. The former medical center still stands in front of the bathhouse.
