Mirror valley train

View into the Spiegelthaler Hoffnungsschacht (1998)

The Spiegelaler Gangzug is a gait disturbance of 7 km of well-known striking extension near Wildemann and Clausthal-Zellerfeld in the Harz Mountains . Initially, the network of veins belonging to the Upper Harz veins was called the Himmlisch-Heerer-Zug after the section immediately north of Wildemann . It is documented that silver ore was extracted here as early as the middle of the 16th century . The Spiegel Valley Gangzug was later named Hüttschental-Spiegel (h) al-Haus Herzberger Gangzug after its course , until the Haus Herzberger Gangzug was viewed independently in the more modern geological perspective .

  • Buschessegener Gang (named after the Buschessegen mine , 1760 to 1802),

The mining of silver-bearing galena focused on the west of the innermost location, about 900 meters long Hüttschentaler Erzmittel and east of the heart, interrupted by a 350 meter long Vertaubungsbereich , a to Spiegeltaler Zechenhaus reaching more mineralized zone approximately 1,700 meters in length. The ores spread over a longer distance in the Spiegel valley and at least in parts in the Hüttschental valley.

Paragenesis, peculiarities

The ore filling, which reached a comparatively shallow depth of around 250 meters, consisted mainly of galena . In addition, there was little chalcopyrite and ores rich in silver near the surface. Sphalerite has not been detected on this passage. Gaits , like on other courses, were siderite , calcite , barite and quartz . On the dump of the Glückauf blind shaft lies reef limestone from the Devonian and Wissenbach slate .

Outcrops

At the shafts Baumgarten (1655–1726), Neue Juliane (1701–1763) and Alte Fundgrube in the secondary center there are duct bites with barite, calcite, quartz and little ore. To the east of the innermost, water outlets point to the Spiegelaler Gangzug.

Overview of mining history

The chronicler Hardanus Hake , who reports on the finding of human bones in an abandoned pit in the 16th century, provides evidence of medieval mining in the Hüttschental . Around 1550 mining was carried out in both the Hüttschen Valley and the Spiegel Valley, about which little is known and which came to a complete standstill by 1629.

After unsuccessful research work in 1662, the mirror valley train was finally prepared for dismantling from 1680 with a large number of pits . Because of its location in valleys, mining was accompanied by considerable dewatering difficulties . The Himmlisch-Heerzug-tunnel , which was driven from the Innerstetal in the years 1552 to 1688 over a length of 2300 meters , brought little success because it was only 46 meters deep. With a production of a maximum of 400 tons per week and a total workforce of around 300 men, mining on the Spiegel Valley Gangzug reached its peak between 1720 and 1740 and was completely idle by 1764 due to depletion of the deposits .

In the following decades, when there were dewatering problems in other areas, the old pits on the Spiegel Valley Gangway were occasionally re-occupied in order to mine ore residues above the tunnel floor. The drowned, deeper burrows were not cleared up again .

With the tailgating a wing place the depths Georg adit from 1807 and the sinking of the mirror Thaler hope shaft from 1816/1817 to 1834 there was a further examination of the Spiegeltaler lode in the eastern area, without causing a disruption came economically recoverable ore. Nevertheless, this passage area was crossed again from 1890 to 1894 by a cross passage from the Ernst-August tunnel and from 1918 to 1925 a blind shaft was sunk near the old Silberner Mond shaft (1685–1765).

In Hüttschental, the Glückauf blind shaft was searched for new ore deposits between 1924 and 1928, until it was abandoned as a result of water ingress at the 350 m level. From 1924 to 1926 and 1953 a brief trial mining of barite was carried out.
