Haus Herzberger gangway

from Wikipedia, the free encyclopedia

When house Herzberger lode is a north of Clausthal-Zellerfeld in the Harz running gait disturbance , leading to the Upper Harz veins belongs. The comparatively short passage is only mineralized over a length of 1400 meters and mining came to a standstill more than 200 years ago due to the exhaustion of the little ore deposits . In historical considerations, the Herzberger Gangzug was added to the Spiegel Valley Gangzug , the western continuation of which it forms via the Buschessegener Gang and the Silberblicker Gang .

Course (projected onto the surface of the day)

Anchoring to the Buschessegener Gang ( Spiegel Valley Gangzug) on ​​the northern outskirts of Zellerfeld - In the Abtshöfen - Unteres Hasental - Schönemanns Kopf - Großes Steintal - Langes Tal - Grünes Tal - Hüttenkopf - Scharing to the Spendetaler Gangzug.

Paragenesis, peculiarities

Because of the long-ago end of the mining extraction the following useful minerals are known only by dump finds: galena , pyrite and chalcopyrite . At gaits were quartz , calcite , dolomite , siderite and barite present, the host rock was composed of shales and greywacke .

Outcrops

At outcrops there are only traces of mining in the form of pings and heaps , especially in the vicinity of the New House Herzberger Schacht .

Overview of mining history

Mining activities on the Herzberger Gangzug house are documented from 1588 to 1768. Despite the limited content of the deposits, around 10,000 tons of lead were extracted and greater economic yields were achieved. This is evidenced by a preserved flag of exploitation from the Prince Christian (1684 to 1729) mine in the Upper Harz Mining Museum .

Starting in 1588, the long tunnel was excavated to a length of 850 meters with mallets and iron to dissolve water . It brought a depth of about 40 meters . From 1690 this task was taken over by a 750 meter long wing of the Frankenscharrn tunnel , which was another 40 meters lower.

From 1925 to 1928, the Neue Haus Herzberger Schacht was brought down to a depth of 631 m to explore the Herzberger corridor. Further investigations were carried out using crosscuts from the Clausthal ore mine ( Kaiser Wilhelm shaft , Burgstätter gangway ). No economically viable ore deposits were proven.
