Laubhütter gangway

from Wikipedia, the free encyclopedia

The Laubhütter Gangzug is a system of gait disturbances in the western Harz . It runs in the Eichelbachtal south of Bad Grund . The southernmost of the Upper Harz veins is divided into the Laubhütter and Sülzkapper veins . During investigations carried out between 1930 and 1961 by the neighboring Grund ore mine , an ore medium with a 700 meter strike and 270 meter decline was discovered.

Course (projected onto the surface of the day)

Course of the three individual courses west of the Fahlenberg not known. Fahlenberg - Former mud pond ore mine Grund (here leafing up in three sections) - Laubhütte (district of Bad Grund, here ore-bearing) - bottom of the Eichelbach valley - Kalbeborn - crossing of the Innerstetal - Johannistal. Further course in the east not known. It is believed that old mining tunnels in Buntenbock explored the Laubhütter Gangzug. The Sülzkapper Gang is located a little south of the Laubhütter Gang and its course has not been explored much.

Paragenesis, peculiarities

Despite extensive mining exploration by Preussag, there are hardly any references in the literature to the mineral filling of the Laubhütte corridor. At Stoppel , only chalcopyrite is mentioned as ore and barite as gangue .

Surface geological outcrops are not known. The course of the aisle is indicated by isolated pings .

Overview of mining history

An investigation of the Laubhütte corridor was carried out through the Laubhütte gallery . This tunnel was probably started as early as the 16th century to serve as a water solution tunnel for the Silbernaaler Gangzug and abandoned after 200 meters. Originally it was supposed to be driven to the Braunschweig House Pit. Another attack took place in 1686, again with the intention of driving the tunnel through to the Haus Braunschweig pit. The tunnel should have a total length of just under 3.5 km and begin its function after 50 years. Due to a lack of ventilation , the excavation of a 5.5 Lachter higher tunnel began in 1705 and 1706, but it was thrown off again in 1717, as ventilation was now possible with technical aids. Since in the further course there was no more light holes and therefore no sufficient ventilation due to the mountains and finally due to high wood consumption, the tunnel was closed in 1719. It had a total length of almost 1.7 km and led exclusively through deaf rock .

Little information is available about further mining attempts. The Sülzkapper passage was opened up by the Sülzkapper tunnel (1794).
