The staircutter (also outdated Trappenauer 1 ) is a 351 m high mountain height southwest of Sachsenburg , a district of the town of Frankenberg in Saxony . Already at an early stage there was intensive mining for silver and copper. Century led to the formation of the now desolate mountain town of Bleiberg .
Description and geology
The predominantly wooded stairwell rises steeply on the right bank from the Zschopau valley with a height difference of more than 100 m, while in the north and east it gently merges into the neighboring landscape. In terms of nature, it is located in the Erzgebirge foothills on the border between the Erzgebirge basin and the Mulde-Lösshügelland .
Geologically it belongs to the outer slate mantle of the Saxon Granulite Mountains . The area is tectonically heavily used and characterized by eruptions . In the north-western part, Silurian rocks predominate , especially blackish-gray, phyllitic slate , knot slate and a larger block of silica slate , in the south-eastern part, on the other hand, kneaded Devonian clay and silica slate and limestone.
The area is interspersed with several parallel, northwest- trending corridors at short intervals . The main course consisted mainly of barite and some quartz with traces of chalcopyrite and was 1-1.5 m thick.
Mining
Mining in this area began in the middle of the 13th century 2 , when rural settlement, extensive silver finds in the Freiberg area and the introduction of mountain freedom by Margrave Otto von Meißen led to the first mountain shouting. Mining quickly gained great importance and quickly led to the emergence of the mining town of Bleiberg . Numerous pits were being mined in a very small space, extracting copper, lead and silver ores in a process similar to Duckelbau . While mining for silver took place along the barite-quartz veins, the copper was extracted from the blackish slate. Mining was stopped again in the middle of the 14th century - and the residents were forced to leave the mining town.
In the 15th and 16th centuries there were unsuccessful attempts to resume mining. The mining industry is said to have been shut down for a long time.
In the 18th century, from the Zschopau valley at the foot of the stairwell, the staircases were driven forward. In particular, in the period from 1740 to 1786, the tunnel was driven over a length of 1209 m. The tunnel followed the main corridor over 380 m and runs almost as far as Sachsenburg. A day shaft and several light holes were also sunk .
In February 1912 the tunnel for water extraction for the city of Mittweida was awarded again.
Around 1947/48 the SAG Wismut was looking for uranium ores.
