The Büchenberg ore mine is a former iron ore mine now operated as a show mine in the Harz mining region in Büchenberg , municipality of Oberharz am Brocken in Saxony-Anhalt .
history
The mining of iron ore in the region is documented as early as the Middle Ages , with mining initially taking the form of opencast mining in so-called pingen . After a heyday of ore mining in Elbingen in the 16th century, mining continued with varying degrees of intensity until 1925, but was then stopped entirely. In the 1930s, however, the region resumed mining. Iron ore mining in the Büchenberg ore mine began in 1936, in particular the needs of the armaments industry were met. The mine had been taken over by Mannesmann . The mining concentrated only on the ore deposits of the mine, the iron content of which was more than 35%. From 1937 to 1940 , an 8,650-meter-long cable car was built from Rothenberg (shaft I) , today's entrance to the show mine , with which the iron ore was transported to Minsleben , where it was loaded onto railway wagons. The material ropeway of the Zenith type had 33 pillars, initially made of wood. The maximum span between two supports was 1262 meters, the diameter of the supporting rope 3.5 centimeters. Four tensioning devices and three road safety devices belonged to the cable car. The system had 74 lorries and was operated at a speed of 2.66 meters per second. 45 workers were involved in handling the transport. The construction company was Bleichert Transportanlagen GmbH Leipzig . Building owner of the cable car in 1940/41 was to Mannesmannröhren- works belonging union Constanze from Dusseldorf with administrative headquarters in Giessen . 840 tons of iron ore were transported away by cable car every day. The ore was smelted in the Reichswerke Hermann Göring in Salzgitter .
After the end of the Second World War , the mine was initially closed. In 1946, however, production started again. The mine was nationalized. For processing the ore, Salzgitter were now in West Germany and came as a processing site is no longer in question, in was Calbe (Saale) , the low-shaft furnace plant Calbe , one specific to the smelting of Büchen Berger ore with Braunkohlenhochtemperaturkoks been deliberate arc furnace plant . In 1958/1959 the cable car was modernized and the old wooden supports were replaced with steel supports while operations continued. New protective nets replaced the old wooden road protection bridges.
After the GDR was able to obtain better iron ore from the Soviet Union , the continued operation of the ore mine was no longer worthwhile and operations were stopped on April 30, 1970. The day facilities were initially used as a holiday property. The cable car was dismantled and scrapped in 1971/1972. Only support number 1 and the drive that is still functional today have been preserved. The mine was to be converted into a show mine. In 1984 the first floor of the mine was again prepared so that the plans could be realized. The exhibition mine was opened on October 7, 1989, the 40th anniversary of the republic, the GDR's national holiday .
Access to the mine is not via the old production shaft , but via a staircase along the entrance of the old industrial cable car into the mine, with which the broken iron ore was previously extracted from the mine. Since 1993 the mine has also been accessible for wheelchair users and people with reduced mobility. The guide path through the mine is 600 meters long. Overall, the mine covers a route network of more than 40 kilometers on six levels, most of which are not accessible to visitors. The mining machines that were used in GDR mining in the 1950s and 1960s are still present in the show mine. The machines and the tack are functional and are demonstrated during guided tours, such as an overhead loader , an ore scraper and several rotary hammers .
Until July 1, 2006, the mine was operated by the city of Elbingerode. The facility has been leased since then.
