Gottholdstolln
The Gottholdstolln , also Gottholds-Stollen and most recently JD No. 2 , is a disused mining facility in the district of Háje (Zwittermühl) of the Potůčky (Breitenbach) municipality in the Czech Republic , which was operated from the 18th to the 20th century. The associated Gottholdstollner colliery house was demolished in the early 1950s, like all the houses in the district of Háje (Zwittermühl). Today only a wooded spoil dump and the buried mouth hole in the Schwarzwassertal remind of the Gottholdstolln.
history
Due to the new mountain blessing that began at the beginning of the 1710s, further ore-laden crevices and passages were searched for in the Bohemian Ore Mountains . Several silver mines began operating in Zwittermühl. Due to problems with the rising pit water and its uplift , these mines came to a standstill in 1743.
After the following year the financially strong Bohemian Grenzzolleinnehmer and town clerk of plates , Johann Franz Hessler (1693-1770), with which he founded Plattner union in the mining went into Zwittermühl, he left in 1746 under the Zwittermühler town center at the black water toward young stallion in In 1758, drive the Gotthold tunnel into the Zottenberg massif to the north as a deep heritage tunnel. The aim of the tunnel was to drive under older tunnels and to reach the Segen-Gottes-Schacht on the road to Halbmeil and thus to ensure their drainage.
The financial investments in the Gottholdstolln were worthwhile, because large amounts of silver and cobalt ore could be extracted in the surrounding mines in Zwittermühl. But already after 1770 the thickness of the veins found decreased, so that the mining had to be completely stopped at the beginning of the 19th century and the Kux owners tried to sell them. On April 2, 1810, the Dresdner Nachrichten reported that the Gottholdstolln had recently become so noble that between 18,000 and 20,000 thalers of silver had been won in one mountain quarter . According to the newspaper, all Kuxe would belong to Saxony, especially those from Leipzig . Only after the end of the wars of liberation did mining entrepreneur Johann David Starck attempt to mine again between 1816 and 1828 , but this was not worthwhile and was therefore stopped. Another attempt at dismantling at the end of the 19th century under the direction of Johanngeorgenstadt entrepreneur Eduard Tröger did not bring the desired success either.
Immediately before 1906 the Gottholdstolln and the water flowing from it aroused interest in the search for sources containing radon. Count Ernst Emanuel Silva-Tarouca acquired the mines around Zwittermühl and hired miners from January 1912. From 1923 onwards, it was operated by a stock corporation, but mining came to a complete standstill by the end of the 1920s. During this time, the Gottholdstolln became known not only for the bismuth finds but also for the so-called food ore .
In the summer of 1946, the Gotthold tunnel was cleared up again by the Soviet occupying forces, represented by the J áchymovské d oly (Joachimsthaler Bergwerke) in the search for uranium deposits, and was given the new designation JD No. 2 . The last increase in overburden on the dump, which is now located near the buried tunnel hole, dates from this time.
