Graul (mining landscape)
The Graul is a historic mining landscape in the Saxon Ore Mountains .
description
The ore district extends from north to south along the Mönchssteig between Grünhain and Raschau and in an east-west direction along the old road from Schwarzenberg to Elterlein . Its subsoil consists of muscovite - gneiss mica - and quartz mica - schists with up to six meters mighty Skarnlagern . The ores are zinc blende , galena , copper and arsenic gravel , pyrite , magnetite and in the corridors of a bismuth , cobalt , nickel and silver formation, skutterudite , silver luster , solid silver, red gold and bismuth ores are found . In addition to an earthy mixture of oxidic and hydroxidic iron and manganese compounds , the primary deposit contains five to seven percent bismuth, which was processed in the blue paint plant in Niederpfannenstiel , two percent cobalt, and also silver, nickel, copper and arsenic.
history
In the 15th century, silver ore was first mined on the Graul. In 1483 the city of Lößnitz was involved with Kuxen. Later they started digging for other deposits. In the Stamm Asser mine , which consisted of seven union mines and buildings in 1790, sulfur, copper and arsenic gravel were mined in civil engineering in the 17th century. The colliery is one of the most profitable in the ore district, supplied iron pebbles for the production of sulfuric acid to Freiberg until the second half of the 19th century, and in 1913 brown iron stone, manganese and bismuth ores. The St. Katharina mine was in full operation at the end of the 17th century, brought out silver and tin ores and by 1800 consisted of five mountain buildings. A separate vitriol factory was operated to process the extracted gravel . A restaurant of the same name on the Graul today reminds of the treasure trove. In the middle of the 19th century, the ore district was one of the most important mining areas in Saxony. The arsenic works east of the Grauls was built in 1788 by the owner of the hut in Beierfeld . The iron ore from the Grauler Revier was delivered to the Schwarzenberger Hütte , the Königin-Marien-Hütte in Cainsdorf and as far as Upper Silesia . In 1831 King Friedrich August II. And the chief miner August von Herder visited the mine of God's destiny , who had already explored the nature and extent of the ore deposits on the Graul for use in the royal Antonshütte the previous year . The most important mines were God's destiny , the tribe of Asser and St. Catharina . In 1884 the Loyalty Friendship Stolln set up in the Schwarzwassertal became the deepest water-dissolving tunnel in the mine building of God's destiny . Regular mining operations in the district ended at the end of the 1930s.
In 1947, the investigation work began on uranium deposits through Object 03 of Wismut AG . In 1948 this work was continued by the object 08 . The excavated shafts were given numbers. Katharina No. 41, Alt Gottes Geschicker Kunstschacht No. 89, Neu Gottes Geschicker Kunstschacht No. 264 and the Herkules Stolln No. 113. The area was explored to a depth of 220 m and 0.3 tons of uranium were mined. In 1950 the work was stopped.
The hut house of Grube Gottes Geschick is privately owned and is being extensively renovated. The roof and first floor of the mining forge next to it were demolished in 2007.
