DMT-Gesellschaft für Lehre und Bildung

It was established as the Westfälische Berggewerkschaftskasse (WBK) in 1864 and merged with the Steinkohlen-Bergbau-Verein (Stbv) and Bergbau Forschung GmbH under the auspices of DeutscheMontanTechnologie e.V.

[2] It also helped to fund construction of the Bergmannsheil University Hospitals in Bochum and the expansion of the network of ship canals that link the Ruhr Valley to areas such as the North sea.

[3] The decades that followed also witnessed numerous laboratories, testing facilities for firedamp experiments in Dortmund and inspection sites for hoisting cables and mining lamps.

At roughly the same time, people were starting to consider consolidation of the many joint technical and scientific institutions maintained by the coal mining industry.

(DMT) was established as of 1 January 1990, which, alongside WBK, also incorporated Steinkohlen-BergbauVerein (Stbv), Bergbau-Forschung GmbH in Essen and Versuchsgrubengesellschaft mbH on the site of the former Tremonia colliery in Dortmund.
