Hard coal mining
The mining law union of the “Vereinigte Klosterbusch” colliery goes back to the Eisenstein colliery Vereinigte Klosterbusch in Essen-Werden . This union acquired the coal unions Sonnenschein, Johann-Diedrich and Buchwald in (Bochum-) Querenburg in 1918.
In Querenburg two were first in 1918 tonnlägige wells put into operation in 1924 was followed by a seigerer (vertical) production well, 1937, a ventilation shaft , and in 1955 another ventilation shaft at the hair line. The extraction reached a depth of 368 meters. The mine was closed on July 31, 1961, and today one of the two broadband seismic measuring stations of the Ruhr University, which is also part of the German Regional Seismological Network (GRSN), is located in one of the tonnage shafts.
In 1926 an annual production of 350,000 tons of edible coal was achieved, in 1937 454,000 tons of coal and after the Second World War until the closure in 1961, over 300,000 tons were produced annually, which were mainly used for domestic heating.

The total production from 1918 to 1961 was 12,987,000 tons of hard coal.
The coal extracted was transported via a cable car built and put into operation in 1920 to a loading station on the Ruhr Valley Railway near the Holland colliery in Herbede . On the left bank of the Ruhr there were also coal washing , processing and the administration building of the colliery. The foundations of the girders are still partially visible in the fields.
The daytime facilities in the Lottental are still partially preserved. At times there was a residential community for student squatters. After the building was occupied for the second time from 1991 to 1994 and in October 1995, it was again empty for a long time. Today there is a faculty library and vehicles from the technical relief organization.
The quarry of the Klosterbusch colliery on the “Kalwes” mountain is the largest geological outcrop in Bochum. Due to its geological importance, the wall has been placed under protection as a natural monument ND 2.5 .
The area in front of the quarry is used as a test area and for composting cuttings from the Botanical Garden of the Ruhr University Bochum. There is no public access for reasons of road safety, but guided tours are offered on certain occasions.
