The Frosch colliery is a former hard coal mine in Sprockhövel- Niederprockhövel. The colliery was also known as Zeche Froschbanck , Zeche Frosch-Stolln , Zeche Deifhuser Banck and Zeche Frosch, Fuchs, Luchs & Knappbank . The mine was one of the oldest tunnels in the Ruhr area . The name of the colliery is derived from the seam sequence in a hollow. The seam frog, a local name for the seam Mausegatt , is the lying seam . Above this are the seams Luchs (= seam Kreftenscheer I), Fuchs (= seam Kreftenscheer II) and Knappbank (= seam Geitling ) , which are also mined in the mine .

history

The beginnings

On July 3, the year 1650 a Jörgen (= Jürgen) Deifhaus after successful prospecting and was presumption in the seam Mausegatt the length field Deifhuser Bank (= Deifhausener Bank) for the reduction of coal awarded . He was the owner of the Diefhausen farm , which, according to the treasury of the county of Mark, was one of the most highly taxed and thus wealthiest farms in the Sprockhövel area as early as 1486. The length field extended over a length of 1.5 kilometers in an elliptical and trough-shaped hollow between the Diefhausen farm in the south-west and the Auf dem Bruch farm in the north-east. After the award by the mountain director and Rittmeister Alexander Achilles on behalf of the Brandenburg Elector, the mine was quickly put into operation. A second award took place on July 2, 1683, and another length field was awarded on January 14, 1715. These further awards were based on the fact that there were four seams in the hollow. Two awards were therefore held for one seam each and one award together for two seams. Naming the seams after animals (frog, fox and lynx) was common in the Sprockhöveler area at that time.

The first years of operation

The mine was in operation in 1737. The tunnel mouth hole of the water-dissolving tunnel of the mine was at approx. 180 m above sea level. NN at Heimbecke north of the Diefhausen farm and its current riding hall, which is located west of Wuppertalerstraße on Hibbelweg. From 1739 to 1762 the mine, of which three shafts (Luchs shaft, Göpelschacht Höchst and Frosch shaft) can be located in the Brelo woodland , was in operation. In 1739 the mine was costly to operate and the Frosch union was founded. The name of the union goes back to the name of the most exploitable seam frog (known today as seam Mausegatt). A survey was carried out that same year. In 1754 a transverse fault was hit and the seam was lost. This year only the frog and lynx shafts were still in operation, one Peter Jörgen Hilgenstock was shift supervisor . In 1775 the mine was mentioned in the documents, it is not clear whether the mine was in operation.

In 1784, the mine field was amended by Diefhauser tunnels solved . This tunnel was specially excavated for this purpose on the Sprockhöveler Bach below the deepest level . The tunnel had a length of 500 Lachtern (1,046 meters) and the tunnel mouth hole was at approx. 155 m above sea level. NN in the area of today's streets Magdeburger Strasse, Erfurter Strasse and Leipziger Strasse. Even today, water is taken from it for the Sprockhövel outdoor pool. In 1796 the mine was opened up using the old tunnel floor. There were two more locations below the bottom of the tunnel . In addition, shaft 4, also known as the Fläings Egge shaft, was in operation that year.

The other years of operation

In 1800 Acker, Crone and Fläings Egge were mined in the area of the shafts. In 1801, a mine surveyor for the Frosch colliery was made by the mining company Honigmann . This drawing is therefore the oldest sketch of all Ruhr area mines. Due to the closed hollow with a fault running transversely to the main direction, the mine was easy to plan and therefore served as a teaching project for journeyman marksmen, which is also the reason for the early inclusion of the crack work. In 1805, mining began below the bottom of the tunnel . That year the Mina shaft was in operation. In 1810 the Amalia, Hope, Höchste, Moritz and Petri pits were in operation. In 1815, Schacht Doris was promoting .

The last few years

In 1820 the Peter and Gustav shafts were in operation, and Ludwig shaft was also in operation as a production shaft. In 1825 the Blücher, David, Ernst and Gustav shafts were in operation. In 1830 the end shaft and a western test shaft were in operation. This year the coal supplies ran out. In 1833 the end shaft and an eastern test shaft were in operation. In April of the same year, the Frosch colliery was closed. The shafts were filled in the following month . In October 1880 , the Frosch colliery consolidated with other mines to form the Sprockhövel colliery . The Zeche Frosch, the smallest participating union, brought in only 76 out of 1000 Kuxen .

Promotion and workforce

The first known workforce at the mine dates back to 1754, when five miners were employed in the mine. The first known production figures of the mine come from the year 1796, at that time six miners were employed at the mine who produced around 1460 tons of hard coal. In 1805 4515 tons of hard coal were mined. The colliery has always been profitable in its long history, as a rule two to ten miners were employed who extracted between 100 and 1000 tons per year. The last known figures for the mine are from 1830, when 823 tons of hard coal were extracted.
