The Hansa mine (historically also: Grube Hermann , also called Hansastollen ) is a disused iron mine in the Bad Harzburg districts of Harlingerode and Göttingerode am Langenberg .
geology
The Hansa mine is divided into two storage areas: The decisive Hansa camp is located on the southern slope of the Langenberg near Göttingerode (coordinates: ⊙ ). The rock image coincides with that of the Langenberg quarry not far to the north . Oolithic, calcareous iron ore with an iron content of approx. 25% is dominant, the origin of these layers lies in the coral ole- lite from the lower Malm . The conveyor systems on the Langenberg later fell victim to the lime mining.
To the north, on the mine site in Harlingerode, which is still there today, is the Hermannslager , which was once characterized by limonite , which is why this area can also be called the Hermann mine (coordinates: ⊙ ). On the site, the Hurle rises for the first time from the Langenberg, it emerges from its piping behind the former factory gate over a short distance and can be dammed here via a small weir.
A third camp, the Hühnerkamplager south of the Harlingerode zinc smelter and about 1.5 kilometers west of the Hansa camp, was abandoned very early due to cross faults (coordinates: ⊙ ).
history
The Harzburg mine director Wilhelm Castendyck found profitable iron ore deposits in what is now Bad Harzburg between 1859 and 1861. In addition to the Hansa mine, this also included the disused Mathildenhütte in today's Westerode and the Friederike mine in Bündheim , which was closed in 1963. The mine was opened up in the year of discovery so that it could start operations on June 3, 1865. The Hermannslager to the north had to be abandoned in 1867 due to insufficient productivity, so only the Hansa camp remained.
After the transport of the ores, which had an initial output of 500 tons / day to the Mathildenhütte, two kilometers to the east, turned out to be extremely difficult by teams of horses, operations had to be stopped again in November of the same year and could only be resumed after a thorough renovation of the path .
The open pit mining took place until 1903, the depth was up to 266 meters. In response to a request from Mathildenhütte to increase performance, large-scale, cross-cutting tunnels with a diameter of 4.2 meters and a north-south length of 500 meters were built in 1902. In the same year a cable car was built that led from the Hansa mine to the Mathildenhütte and opened on May 27, 1903. The annual production was around 6,000 tons before, but by 1930 it had grown to a level of around 30,000 tons / year.
However, the operation of the Hansa mine was not without economic problems: Due to the global economic crisis , the Hansa mine together with its sister mine Friederike was shut down on March 15, 1932 and did not resume service until November 1, 1935. In 1937, 248 people were employed in the Hansa mine. At the turn of the year 1938/39, the mine received a siding to Harlingerode station . For this purpose, an approximately 300-meter-long chain railway was built, which led from the mouth hole on the mine site to the ore loading ramp. The cable car to Mathildenhütte was dismantled on May 20, 1943 and rebuilt in Konin in what is now the Greater Poland Voivodeship .
From the Second World War and especially in the course of the Korean War , production was increased significantly thanks to the recruitment of Silesian miners, so that in the last few years the mining operations resulted in expansion construction south of the Langenberg in the area of the Göttingerode settlement . This led to extensive mountain damage , which could only be fully compensated in the course of the last third of the 20th century.
After almost 100 years of operation, the plant was shut down on August 23, 1960 due to unprofitability, and a total of three million tons of ore was mined. The former headframe was blown up in May 1962.
Subsequent use
After the closure, the chain railway to the station was demolished and the area north of the Landstrasse was completely built over. The area, which is now limited to a small area west of Göttingeröder Straße, was used by various companies, some of which carried out renovations and extensions. Today the area is used as a mixed area; the former office and the suite rooms are inhabited and a residential building is added, while the remaining buildings are used commercially.
The mine site south of Göttingeröder Strasse was bought by Rohstoffbetriebe Oker GmbH & Co. , which mined lime as part of the Langenberg limestone quarry until 1985 . In 1999, the Europäischeaurus was discovered here, which is why the Langenberg gained special geological importance.
The street name Hansaweg in the neighboring district of Göttingerode still reminds of the former pit . The mine site on the Göttingen side no longer exists and the shaft entrance on the Harlingerode side has been sealed inaccessible under the supervision of the mining authorities.
