The Stahlseifen mine was located outside Salchendorf in the municipality of Neunkirchen in the Siegen-Wittgenstein district .
history
The “Stahlseifen” mine was on the road connecting Salchendorf and Wilden . Ore was mined from the 18th century. On March 31, 1827, the Prussian Mining Authority granted the right to mine iron ore . The passageway was developed from a tunnel excavated in the Wildebach valley , which only brought a depth of 27 m. In the 1830s a 95 m deep artificial shaft was created using two water wheels. Almost 20,000 t of iron stone were extracted from this shaft. In 1873 it was decided to sink a new shaft. The following (partly later) floors of this shaft are known: 125 m, 155 m, 190 m, 230 m, 270 m, 310 m, 360 m. In 1885, 210 t of spate iron stone and 22 t of zinc blende were mined, shortly afterwards the production was stopped. The depth of the pit was 158 m up to then.
In 1907/08 the mine was connected to the newly built valley railway of the Free Grunder Railway . Before the First World War , a 1400 m long corridor was laid out on the 310 m level in the direction of Heinrichsglücker Grubenfeld. On the 360 m level, a blind shaft was sunk to 596 m and the deepest level was set up there. Together with the mine building of the Heinrichsglück mine, a depth of 740 m was reached. 1934, was promoting yet at 80,000 t Rohspat. At the end of the day, 283 staff members, including nine employees (a total of 85 for days), worked here. The ore was roasted in ten roasting ovens at the daytime facilities .
Aisle means
The occurring Spateisenstein means strike like those of Heinrichsglück from east to west and have a southern dip with approx. 65 °. The first medium was close to the shaft and was 1.5–2 m thick and 45 m long. Zinc, lead and copper ores also occurred in the eastern part of the Middle. The second mean was seen from the first about 70 m further to the west, had an average thickness of 2.5 m and had been crossed over a length of 76 m. Antimony ores were found in nests here. The mined gangue medium steel soap (medium 1) reached thicknesses of 5 to 11 m and consisted of spate iron stone, pyrite and lead ore as well as barite and ullmannite . Other mine fields such as Stahlseifer Hope and Stahlseifen I - IX , which were partly awarded on iron alone, partly on iron, lead, copper and zinc (Stahlseifen III was awarded on antimony-nickel), served to round off the mine holdings. All pit fields together extended over more than 1 million square meters.
Mine network
In 1897 the Ruhr concern Phoenix bought the Heinrichsglück and Stahlseifen mines and turned them into the Heinrichsglück trade union . A cable car later led over the Hardtwald from Heinrichsglück to the Stahlseifen mine . After mine operations at the Heinrichsglück mine had already been closed around 1900, steel soap operations did not come to an end until January 31, 1935. A total of 1.452 million tons of iron ore were extracted from both mines.
In 1937 the Neunkirchen factory owner Karl Roth acquired the mine site and founded the Heinrichsglück factory for iron and metal processing here . The remains of the old pits were dismantled and scrapped. Most of the old halls of the Stahlseifen mine are now used as warehouses and for small businesses, some of which have been expanded or added. The site of the pit is still called "Heinrichsglück" today, although the actual pit with this name was further north.
Consolidations
A consolidation existed with the nightingale pit . It was shut down in the 1860s and in the same decade produced 48 t of brown and spate iron. The Landmann mine was also shut down in the 1860s. Heidenberg in Salchendorf was awarded in 1732 and closed in 1920. The Heidenstock mine was operated before 1860.
