The pit Mathilde was a lead and zinc ore mine in Helmeroth in the municipality Hamm an der Sieg in the district of Altenkirchen in Rhineland-Palatinate . The pit was north of Helmeroth on the western bank of Nister and was a rather insignificant pit in the Siegerland ore district . Lead and zinc ore containing silver were mined .
history
The Mathilde mine emerged from the consolidation of the individual mines Gute Mathilde , Guter Heinrich and Gustav Adolph in 1868 . Individual pits had existed since 1866. The consolidated mine field was lent to lead, zinc, iron and copper. The pit had an upper gallery ( location ), an approx. 500 m long deep gallery at 155.6 m above sea level on the Nisterufer ( location ), as well as a machine shaft ( location ) and a production shaft ( location ). The mining of the ores , which were later transported to the Siegtal by cable car, took place up to the 140 m underground level, which could be reached via cesspools from the deep tunnel.
Aisle means
In a specially folded hollow area between the Wehbacher and Wissener saddles, several rather insignificant ore veins occur. It is a short NW-SE trending, SW-sloping corridor with several individual corridor means (e.g. means Gustav Adolph), which consist of zinc blende and silver-rich lead ores. Spateisenstein was also present in small quantities but was not mined.
Successor use
Today there is a campsite on the area around the deep tunnel. In 2010, the outflow of pit water from the deep tunnel was examined to estimate geothermal potential uses .
