"... The Teutoburgia colliery was a hard coal mine in Herne-Börnig.
On September 10, 1855, the businessman Carl Wilhelm Rüping came to Holthausen and found what he was looking for. He called the seam "Laura". On August 6, 1856, he met a second time, at Gut Schlingenberg between the Callenberg house, the community of Holthausen and Obercastrop. The prospects were bought in 1866 by William Thomas Mulvany, who sank the first shafts. It soon turned out, however, that the mine field was too small for profitable coal extraction. Mulvany sold the mine pretty quickly.
As a buyer, the Bochum Association for Mining and Cast Steel Manufacture sunk shafts I and II again between 1905 and 1909 and started operations on April 1, 1911. But just eight months later, a serious mine accident occurred. Six miners were killed in a firedamp explosion. A year later there was another firedamp explosion, again with six deaths.
This colliery did not seem to be really profitable, despite its peak of over 1,100 miners, because there were repeated rumors about its closure and just as prompt denials. The rather dry coal was hard and impermeable to water - the ideal soil for the construction of the Rhine-Herne Canal in this region, but coal mining required enormous efforts and resources. The colliery was shut down in 1925. A good number of the 1200 or so workers found new work in the neighboring Constantin and Mont Cenis collieries. In 1929 the breakthrough took place between the Erin and Teutoburgia collieries in order to use Erin’s remaining reserves. At first, the shafts on Teuto were only used as weather shafts, before Erin's cable trip took place here. It was not until 1941 that Erin began to mine coal again on Teuto. This continued until 1983 before it was finally shut down, which meant that 3800 miners were suddenly unemployed. ... "
