The Verlorener Sohn colliery (originally Verlohrner Sohn ) was a small mine in the Winz-Baak district of Hattingen and the Linden district of Bochum . The last visible remnant of the shaft , which is up to 260 meters deep, is the masonry of the loading ramp, over which 1 million tons of coal was loaded. You can still find it today on the street “In der Aar” (until the 1960s it was called “On the prodigal son”). In the immediate vicinity is the mining field of the North Pole small mine on Surenfeldstrasse in Linden and about 300 meters west of the Ruhr Valley small mine and further that of the United Dahlhauser Tiefbau mine . In its heyday, up to 250 buddies were created.

First dismantling phase

Mentioned in a document as early as the 18th century , the facility was in operation at least from 1839 to 1924. It was officially put into operation on May 1, 1906 and consisted of two tunnels . The first coal loading was accepted by the mining authorities on November 6th, 1906. Since the mining was not profitable, the operation above the tunnel floor was shut down in 1912 and tried in deeper layers. For this one was Schacht to that in 125 meters depth lying civil sole beaten. In 1913 it belonged to the United Glückauf limited mining company. One began with the sinking of a main production shaft . From this year fat , food and lean coal were mined in three seams on a bed at 55 m .

Starting from the remaining loading ramp, these seams and thus also the mining area are located parallel to the streets Im Lange Siepen and Bachstraße in a north-easterly direction. You cross Dahlhauser Strasse between houses 87 and 99. There was a machine room and a die shaft. According to the report by the Gelsenkirchen Mining Authority from November 17, 1913, there was no major mining in the Silberbank seam . There were at least 5 breaks and a straightening section between the other two seams .

According to the expert report, the following 3 seams, calculated from the hanging wall to the lying wall, were built from the tunnels and the partial floors :

  1. Silver bank seam , thickness 2 m coal, in the years 1908–1910 both above and below the bottom of the tunnel with a mountain offset
  2. Seam large side bank , thickness 0.82 m coal, in the years 1908 and 1909 above the tunnel floor with mountain offset
  3. Seam of sunshine , thickness 3 m of coal in the years 1909–1911 above and below the bottom of the tunnel up to the 2nd partial level with mountain offset

However, since the number of tonnes extracted was constantly decreasing, the mine was shut down before the First World War .

Second phase of dismantling

After the war they tried again to mine coal. In the 20s the bill received a modern development with washes , coal tower and other above-ground facilities . Thus, she had an office building, a laundry , lamp room , briquette factory , screening plant, horse stable and magazine. A small locomotive drove over the loading ramp and the bridge to the screening plant, because there was also a petrol locomotive shed north of the ramp.

At that time, the Verlorener Sohn colliery was also connected to the middle Ruhr Valley Railway between Hattingen and Dahlhausen , which was still independent at the time. The connection was made to the west via the nearby waterworks to the siding of the Dahlhauser Tiefbau colliery .

bankruptcy

In October 1924 the operator filed for bankruptcy . Thereafter, according to tradition, the Winz-Baaker Ruhrhöhen continued to be mined until around 1926. In the summer of 1929 all buildings were demolished and the tracks for the connection to the middle Ruhr Valley Railway were removed.

During and after the Second World War , coal mining in the fields of "Verlorener Sohn" continued to be "black". The stones of the tunnel entrance ( mouth hole ) were used in the post-war period to repair a nearby barn.

The German hard coal needs (DSK) has subsequently taken the bill free from exposure, allowing for future required safeguards, property owners pay. The mining damage caused and incurred by the mining was finally settled in bankruptcy proceedings in 1924 with a local court decision of November 6, 1926. In 1925, Bergbau AG Baak took over the mine field of the "Verlorener Sohn" colliery as part of an auction. Today it belongs to the Poerting / Carl Funke shutdown area .

Day breaks

A large part of the seams was not backfilled , so that from the 1950s onwards there were major day breaks . In 1955, a child narrowly escaped an accident on his scooter. Later, while plowing, a tractor disappeared halfway in a daybreak and had to be lifted out with a crane. On February 12, 1970, north of the road in Long Siepen on Dahlhauser Strasse, Hattingen's greatest daybreak occurred. With a depth of 80 meters one of the largest in the entire Ruhr area. Even the WDR television reported about it in the program "Hier und heute". A recording of the broadcast can be found in the WDR archive.

Around 6:45 p.m., a crater about 15 meters in diameter formed from the middle of the street at number 87. The bus 59 (now 359) with 31 passengers escaped a catastrophe only with a successful maneuver by the bus driver. A 15 meter high power grid mast disappeared without a trace in the depth. According to a newspaper report by the Westdeutsche Allgemeine Zeitung (WAZ) of February 5, 2000, a transformer house later sagged . The transformer could no longer be saved.

The break in the day was covered with a large concrete slab, for which more than 130 cubic meters of concrete were built. The area is still regularly examined by the responsible mining authority in Gelsenkirchen.
