The bill Eintracht civil engineering was a coal - mine in Essen - Freisenbruch .
history
founding
The colliery was created as a continued civil engineering operation of a tunnel mine that had been in operation for a long time . The Eintracht tunnel was put into operation in Freisenbruch as early as 1765 . The authorization of this tunnel operation was continuously increased. In 1818 a union under mining law was founded. Several large minefield holdings were consolidated and the Stollenzeche was continued as a union of the Eintracht Erbstollen .
After the stocks were increasingly exhausted at the height of the bottom of the Erbstollen, the union was consolidated into the union of the Eintracht Tiefbau coal mine in 1856 after another mine field enlargement with Zeche Unity . In the same year, the sinking of shaft 1 (today between Bochumer Landstrasse and Morungenweg) began south of Bochumer Landstrasse in Freisenbruch . This could go into promotion in 1858 . The old Erbstollen continued as a water solution path for the new deeper mines used.
In the 1860s a second shaft called Justus was sunk, but it did not stay in production for long.
In 1883 a coking plant was blown on the Eintracht Tiefbau 1 mine . When it emerged after 1890 that the Eintracht Tiefbau colliery would primarily be able to mine edible and lean coal, extensive expansion and renovation work was carried out by the Eintracht Tiefbau union.
In 1894, the coking plant at Shaft 1 was taken out of operation again because the mine was no longer producing enough coal that could be coked. In 1897, shaft 1 received a new steel headframe . In 1898 a briquette factory was put into operation on shaft 1 for the extraction of edible and lean coal .
From 1910 to 1912, alongside shaft 1, shaft 3 was sunk as the new main production shaft and put into operation. This was given double funding. After its completion, the small weather shaft on Plant II was dropped and filled . Shaft 1 was continued as a weather shaft. The production reached 630,000 tons with 1970 employees.
In 1987, more than sixty years after the colliery was closed, the column in the filled shaft 3 suddenly sank to a depth of 380 meters. The backfill required around 20,000 tons of tailings and the shaft would be secured to the ground with a 60 meter thick concrete plug.
Eintracht Civil Engineering II
After 1873, a second separate plant was sunk on Alleestraße in Freisenbruch. Here the top layer of coal was only 18 meters below the surface of the earth. This plant went into operation in 1877 under the name Eintracht Tiefbau II with the third of the four shafts of the entire Eintracht Tiefbau colliery, the Heintzmann shaft . The Heintzmann shaft was named after Edmund Heintzmann, a tradesman and district judge, son of mountain councilor Heinrich Heintzmann .
In 1882 a coking plant was added, which was expanded and modernized several times by 1913 and finally shut down in 1914. In 1913 the still-preserved coking coal tower was built from concrete. The tower, which is rare in its construction, served as an intermediate storage facility for the coking coal on the way to the coking plant.
From 1896 a small broken weather shaft was sunk (broken = first vertically, then leading downwards at an angle).
Shutdown
After the First World War it emerged that the colliery's economically viable supplies at the time were gradually being exhausted. In addition, there was an extreme deterioration in the sales situation for lean coal. The Eintracht Tiefbau trade union therefore decided to shut down the entire conveyor system in 1925. The colliery was closed on August 1st.
The shafts were filled and the daytime facilities demolished. The mine field was acquired in 1926 by the union ver. Constantin der Große owned by Friedrich Krupp AG and kept in reserve. In 1937 the Langenbrahm union bought the mine field. Parts of the mine field were leased to the mines Katharina , Neu Mecklingsbank and Lucia .
Current condition
After the demolition of the daytime facilities, there are no more traces of the buildings of the Eintracht Tiefbau colliery. Some of the broken tunnel mouth holes in Freisenbruch may have belonged to the old Erbstollenzeche.
On the Eintracht Tiefbau 1/3 shaft, in the corner between Bochumer Landstrasse and Freisenbruchstrasse, there is now a residential development on the edges, on a green area on Bochumer Landstrasse - behind the Kroeger upholstered furniture market - are the locations of the former shafts 1 and 3 can still be seen on the basis of inspection openings with manhole covers and corresponding signage, with shaft 1 with several degassing nozzles being clearly visible right next to a park path on a meadow, while shaft 3 is somewhat hidden in a bush area next to a high-rise apartment building. This shaft 3 sank in 1987 to a depth of almost 400 meters. The shaft then had to be filled in a laborious manner and was then closed with a 60 meter thick concrete plug.
The former plant II - Heintzmann shaft - was at the end of today's Alleestraße in Freisenbruch. In addition to some remaining buildings in which the grease factory Dr. Fritz Velten was the last trade, there is still a very rare and therefore historically very valuable coking coal tower in the Ruhr area, which a citizens' initiative has been trying to preserve for years. The two former shafts, the Heintzmann shaft and the weather shaft, can still be recognized through inspection openings with shaft covers and signs in the forest and bush area to the left of the extended Alleestraße. The former rail connection to today's Steele-Ost station, formerly Steele-Hbf, whose route leads through the Bergmannsbusch, has been converted into a hiking and cycling path. At the Sachsenring, a bus stop on bus route 174 bears the name Schacht Heintzmann to this day .
