Neusilberhoffnung is a closed mine on Hundsmarter near Pöhla in the Schwarzenberg mining area in the Saxon Ore Mountains , which operated until 1924 and in which mainly lime and iron ore were mined.
geography
location
The tunnel mouth holes , the former limestone quarry and the pit's daytime facilities are located about 500 m north-northeast of the Pöhla cemetery.
geology
It is a 16-30 m thick rock package of two camps of dolomite marble, some with in its footwall magnetite mineralized pyroxene - skarn lead. The bearings strike 45–60 ° NE-SW and dip at 15–25 ° to SE. The upper magnetite bearing reaches a thickness of up to 2.5 m and the lower magnetite bearing between 1.5 and 2 m. The upper bearing is smear mineralized weak. The ore flow increases after the depth . The lower bearing was mineralized in the strike with silver-bearing galena and sphalerite . The mineralization was caused by a translation fault . While the galena mineralization quickly stopped at depth, the sphalerite mineralization moved further into the depth and was then replaced by magnetite mineralization. Further faults penetrating the camps led to mineralization with arsenopyrite , pyrite and chalcopyrite .
history
The Neu-Silberhoffnung treasure trove was lent to the owner of the Pfeilhammer hammer mill , Carl Ludwig von Elterlein , on April 2nd, 1827 as a self-leaning mine . In the first year, 480 grams of silver were mined. In addition, the pit brought out lead. The magnetite guidance of the deposit was only discovered through mining. As early as 1830, however, no more silver was brought out. By order of the Ministry of Finance of March 2, 1833, the mine received an advance of 150 thalers. In 1837 an artificial wheel with a diameter of 17 feet (4.80 m) was erected and a field linkage 63 cubits long (35.7 m) was built to the newly sunk, 12 Lachter (24 m) deep open pit and artificial shaft . On January 18, 1841, the artificial shaft broke over a length of 10.6 m from above ground. He was then bricked up. When the break was being worked through, there was an after-break on January 20, 1841, in which the mountain huts Carl Heinrich Pfab and Carl August Weigel had a fatal accident.
In July 1846, Porst & Co. took over the factory in Pfeilhammer and also the Neu-Silberhoffnung mine. The mining operations were intensified. At times 17 workers were employed. However, the company never managed without penalties . In 1863 the company was closed.
In 1868 a worker and a riser began to repair the tunnel. On May 1, 1871, the Queen Marienhütte in Cainsdorf took over the mine from the Deutsche Reichs- und Continental-Eisenbahnbau-Gesellschaft zu Berlin. In the same year magnetite mining was resumed with 18 workers. In 1894 the mining operations were temporarily stopped. Since 1871, 19,516 tons of magnetite and 165.5 tons of limestone had been mined. The highest extraction with 1761 tons of magnetite was brought out in 1883.
In 1897 the promotion was resumed. However, the mine was put back into the deadline in 1902 . Until then, another 4,723 tons of magnetite had been extracted. On April 1, 1907, clearing work began in the pit and in 1909 the machine shaft was rebuilt. After that, operations were stopped again.
A sale of the mine planned for 1911 failed. On July 19, 1912, the Queen Marienhütte again applied for a deadline. In November 1913 an ox fell into the open old art shaft, which was then covered. On January 14, 1914, the machine shaft broke. The shaft that had been scalded on the bottom of the tunnel was then filled. After the Queen Marienhütte was taken over by the Sächsische Gußstahlwerke Döhlen in August 1916 , they became the new owners of the mine. On May 20, 1917, the Herkules-Frisch Glück mine in Waschleithe asked the Oberbergamt to take over the mine in order to mine lime and magnetite. On May 26, 1917, the chief mining authority threatened the cast steel factory with the withdrawal of the mining rights. The company was accused of doing nothing for the extraction of iron, which is essential for the war effort. On June 17, 1918, operations were resumed with a three-man workforce and the machine shaft cleared. A few days after the work was completed, the manhole broke again on October 31, 1918. The shaft was then covered and work was stopped. In April 1919 the tunnel and in August 1919 the machine shaft were cleared. In 1920 the mine workings began to be swamped. On February 15, 1921, an area of 34,316 m 2 was muted to expand the mine field . The mine field thus had an area of 73,916 m 2 . The machine shaft was cleared to the deepest level, the 58 Lachter route, and an electric hoisting machine was installed by the Anna Fundgrube in Straßberg . Magnetite mining began in 1921. Since hardly any alignment work was carried out due to the high financial burden, it was foreseeable that funding would be discontinued. In September 1924 the operation was stopped and the mine was put on hold again. Up until then, 2522 tons of magnetite and 208 tons of limestone had been mined. The machine shaft was filled up to the 12 m watercourse. On September 10, 68,916 m 2 of the mine field were released. Only a remaining area of 5,000 m 2 remained in the possession of the cast steel works under mining law. In August 1928, the Saxony Group of the German Aviation Association (DLVeV) took over the mine site. The DLVeV's Schwarzenberg-Raschau gliding school was responsible. After the liquidation of the glider pilot school, the mining rights were given up in September 1934 and the mining rights deleted in January 1935. In 1935 the mine field was examined by the Freiberg State Storage Research Center . After a geophysical investigation in 1936, the deposit was classified as a very small deposit and mining was postponed.
Reuse
The former day facilities ( hut , forge and car garages) were then expanded as a glider piloting school for young pilots for the Upper Ore Mountains Aviation Association and in 1928 the Saxon glider piloting school Schwarzenberg-Pöhla was founded, which was used until the outbreak of World War II.
The glider pilot school was operated until 1958; later the buildings were demolished and covered with garages. The foundations of the hut house have been preserved and serve as the foundation for one of the garages.
