The Eiserner Union composite mine was an iron ore mine near Eisern , today a district of Siegen in Siegerland . It was located on the western slope of the Eisernhardt in the upper Hengsbachtal at an altitude of approx. 370 m and was one of the deeper pits in the Iron District.
Aisle means
The main corridors were the Rader Gänge ( old wheel , water wheel , etc.) with a length of 75 to 120 m and a thickness of 0.75 to 1.25 m, the Sinternzeche corridor , up to 250 m long and an average of 1 m thick as well the Union Stollen corridor . Most of the many small vein deposits had been lost by the 1860s. Mainly brown iron stone was used , partly streaked with iron luster . The Eisernes Kreutz corridor was 60 m long, 0.3–1.5 m thick and led to Spateisenstein with copper pebbles and zinc blende . Ancillary or smaller corridors were Vitternzeche , Mittelste Birke (3–5 m, sometimes less than 0.5 m thick), Collapse , Harteborn , Abendstern , Friedensburg and Taubes Rad . From the 7th floor , the presence of the mine were worse.
history
In 1801 the Union tunnel in the Hengsbach was created to solve the Friedensburg , Harteborn , Abendstern and Hinterste Sinternzeche pits . In 1869 3,940 t of brown iron stone were extracted from it. At that time, this was the highest production of the mines located in the Union area. In 1871 the more than 2 km long Morgenröther Erbstollen was created.
In 1887, the remaining pits built on the corridors were consolidated to form the Iron Union . In the Morgenröther Erbstollen a blind shaft , the Kuhmichel shaft , was built three years earlier, in 1884 . In 1885 this reached a depth of 53 m and later a total depth of 109 m, on which two levels were laid. To vent the smoke, an overflow was cut to the surface and a brick chimney was built on the western slope of the mountain. In April 1898 the first cable car rides took place. Since 1883 there was already a connection to the Eisern-Siegen railway near the Eiserner Hütte via the Morgenröther tunnel . In 1899 it was joined with the neighboring Glücksbrunnen mine . In 1900, a day shaft was built near the Union tunnel to enable deeper access to the corridors . This was five meters in diameter, reached a depth of approx. 130 m in 1901 and thus reached the Morgenröther Erbstollen . In the same year the mine was deferred due to lack of capital.
As early as 1906, operations were resumed with 40 miners. In the same year almost 10,400 t of iron stone were mined. Digestion work showed a positive course of the funds. This was followed by the construction of a processing and roasting plant as well as a cable car to the Eiserner Hütte on the Eisern-Siegener Railway. Most of the further dismantling took place on the Glücksbrunner Gänge. Until 1908 the production did not increase particularly, 99 miners extracted 10,573 tons of iron ore. In 1909 the fourth or 450 m level was reached. The fifth and a year later the sixth or 560 m level followed. The total depth of the shaft was 615 m. On the seventh level a blind shaft was dug up to the tenth level at a depth of 760 m around 1915 in order to get closer to the Glücksbrunner means. The total depth to the earth's surface was then 788.9 m. However, the outcrops of the mine, which now belongs to the Deutsch-Luxemburger Bergwerks AG, were moderate. On July 31, 1925, it was suddenly shut down.
Consolidation pits
- Iron Cross , in operation in 1883/84. Spateisenstein with copper gravel and zinc blende were funded.
- Glücksbrunnen , one of the largest companies in the network. The Glücksbrunner tunnel was created around 1800. In 1899 it was consolidated with the Iron Union . In 1900 an unknown iron stone entrance was discovered 160 m above the bottom of the tunnel. The mine was connected to the Eisern-Siegen Railway. In 1865 5,370 t, in 1866 6,605 t and in 1885 1,460 t of iron ore and in the same year 4 t of copper ore were mined. The passage center was between 1 and 4 m thick.
- House of Orange , around 1800 an hereditary tunnel was built. 100 kg copper pebbles contained up to 28% copper; 100 kg of pale ore up to 980 g of silver.
- Hohler Stein was first mentioned in 1655. A tunnel was dug in the Leimbachtal. Civil engineering began in 1880, the shaft was 2.6 × 4 m in size with a depth of "only" 175 m. After it was closed it was backfilled until 1969. In 1879 eight members of the workforce extracted approx. 938 kg of iron ore (18.24 Ctr ), in 1885 it was already 4,527 t of spate iron stone.
