The Barbecke I mine was the smallest iron ore mine in the Peiner area. It was on the outskirts of the Lower Saxon village of Barbecke in the direction of Söhlde . It built on the same debris ore deposit of the Upper Cretaceous as its much better known neighboring mine, Lengede-Broistedt .
geology
The Lengede-Broistedt iron ore deposit was formed by an elongated trough of around 10 km². In this outsourced the upper Emscher -Sea washed Toneisenstein- geodes from. The mining area of the Barbecke I mine was on the western edge. The camp emphasized here in the north to day and fell five to seven gon to the south. The thickness varied between one and five meters. Average later Fördererz contained 26% Fe , 20% CaO , 14% SiO 2 and 1.6% P .
History and technology
Most of the Berechtsame in Lengede-Broistedt was the Ilseder hut held. Mining began in these areas as early as the middle of the 19th century.
In contrast, the relatively small Barbecke I mine field was lent to drilling contractor Anton Raky in 1921 . He sold it to August-Thyssen-Hütte AG in the same year . With the establishment of the United Steel Works (VSt or VESTAG) it came into their possession.
VESTAG's Rohstoffbetriebe AG did not start mining activities until 1936 under pressure from the National Socialists as part of the four-year plan . The mine was exposed by a collapsing brake mountain from above ground. From there were sublevels in the strike of the deposit ascended from which the reduction in the upward ( floating ) Pfeilerbruchbau done. During the alignment and fixture work in the ore body , 6000 tons of ore were extracted for the first time .
The mined ores were transported above ground on conveyor belts . In the first few years of operation, a cable car transported the unprocessed ore to the rail loading station in Woltwiesche .
The highest production in 1940 was around 400,000 tons per year. With the collapse of Germany at the end of the Second World War , operations came to a standstill and resumed in 1946.
A processing plant was completed and put into operation in 1947. The clayey Lengeder ore could be easily processed by washing. In the period that followed, two mud ponds were created to settle the mountains . The highest post-war production was reached in 1952 with around 225,000 tons and fell steadily in the following years. Due to the limited ore reserves, the technical equipment of the mine was always limited to the bare essentials. Since 1953 the mine belonged to Barbara Erzbergbau AG .
At the end of 1961, the most important steel companies in the Ruhr area decided not to purchase domestic iron ores in the future. At this point in time, a ton of German ore with about 30% iron content cost around 100 German marks , a ton from Sweden including transport cost 51 German marks with 60% iron. Barbara Erzbergbau AG, whose shareholders were Ruhr groups, decreed the closure of the Barbecke mine in July 1962 as the first of its mines. The remaining pillars were dismantled from the Mathilde mine by the Ilseder Hütte in the following years .
After the mine ceased operations, all daytime openings were closed and the mud ponds and the broken fields recultivated. The company buildings were sold to other commercial users, or parts of the facility that could not be reused were demolished.
Current condition (2009)
The company premises consist of two parcels. In the eastern area ( Hauptstrasse 37 ) were the administration, chewing and auxiliary buildings. This part is used today by Edaphon-Humuswerk GmbH . The simple buildings have now been changed and supplemented by other buildings, so that the connection with a former mine can no longer be deduced. To the west ( Hauptstrasse 57 ) is a complex with the former processing buildings. They are multi-storey, cubic concrete structures with flat roofs. Originally they were connected to each other and to the mouth of the towing shaft with ribbon bridges . One of the buildings can now be rented as an event space.
