History of the Amalia Pit in Bochum-Werne
Extensive documentation and publications exist for many pits in the Bochum area. However, the mines that were merged to form the Robert Müser complex have largely been forgotten. There has been no major publication on Robert Müser since 1936, and only a few are aware of the importance of the now virtually unknown Amalia pit. Yet in terms of coking technology and processing of coal by-products, Amalia always played a leading role until the basis for the chemical industry's feedstock was completely switched to oil-derived products in the 1960s and 1970s.
The major advances in technological development, the reconstruction 60 years after the end of the Second World War and this year's 150th anniversary of Harpener Bergbau Aktiengesellschaft (today HARPEN AG, Dortmund) are all reasons for this essay incorporating experiences and reports on the history of the Amalia pit.
