Egestorf tunnel
The Egestorfer tunnel is a monument protected former mine stollen in Deister at Barsinghäuser district Egestorf in the Hanover region .
prehistory
There is evidence of a coal mine in operation in the Deister as early as 1639. In the 19th century there were many places to plant new mines for promotion in to cm to 100 powerful coal seams encountered Wealdenkohle .
In 1845, the state mining administration began building a tunnel in the Stockbachtal on the Hohe Warte, after the König-Wilhelm-tunnel, a quickly successful private mine, had opened the year before in the immediately adjacent forestry district .
The Hohe-Warte tunnel was east of the Nienstedter Chaussee, which enabled coal to be transported; today this is state road 401 to the Nienstedter Pass. In the following years it was supplemented with several entry routes on the west side of the Chaussee. Total coal production rose to 26,773 t in 1871, but then declined.
The Egestorf tunnel
In order to get to further, deeper coal deposits , the Egestorf tunnel was driven from May 1874 . The mining administration had already bought the mining rights for the area in 1854 for 30,717 thalers . At Mundloch am Stockbach, an area first had to be leveled for the necessary operational buildings. After driving 608 m, a 50 to 63 cm thick seam was developed in 1876 .
The coal was finally carried out of the 720 m long tunnel over a brake mountain and with the help of horses over 1.2 km to a loading platform at the Deisterbahn , which opened in 1872, and transported away by rail. In 1877 273 miners were employed in the Egestorf tunnel . The production volume rose to 45,272 t by 1883/84 and remained at about this level until 1897, when it declined due to depletion of supplies and the production was initially stopped on November 1, 1898 after a total of 1.3 million tonnes of coal had been mined. The Egestorf tunnel was also used to ventilate the monastery tunnel , to which a breakthrough had existed since 1882 .
In the years 1914/15 to 1920/21, coal in quantities of 50 to 80 tons per year was extracted again via the Egestorf tunnel .
In 1983 the plan to develop the easily accessible Egestorf tunnel into a visitor mine failed because bats had settled here in the meantime . Instead, the Barsinghausen monastery tunnel became a visitor mine .
Further mining on the Hohe Warte
From 1919 coal mining began again at several other locations on the Hohe Warte. From 1923 to 1931 a 600 mm narrow-gauge railway was used for transport, which led from the loading areas at the tunnels to a brake mountain , over which the coal wagons were lowered to the loading dam on the railway line. The production, which was increased to 35,169 t in 1922, fell to 7056 t in 1930, so that the narrow-gauge railway was discontinued in 1931 and then dismantled. Coal production on the Hohe Warte and on the Grünen Brink was completely stopped in 1942. Since the railroad tracks and loading facilities were dismantled, the coal had been transported to the colliery site at the Barsinghausen monastery gallery by truck .
In 1955 and 1956, the two Hoffmanns tunnels at and above the closed Hohe-Warte tunnel were excavated and any remaining fields that had been left standing two years earlier were mined.
Others
In 1880, 126 of the 291 miners from the various state-owned Egestorf mines and others from the neighboring private mine at Kniggenbrink in Wennigsen lived . In order to shorten the long way to work, from 1875 some of them built houses on the outermost boundary between Wennigsen and Egestorf. Today's Wennigser district of Wennigser Mark arose from this miners' settlement .
In the vicinity of the Egestorf tunnel, other mine tunnels used by bats have been placed under protection in the Deister. The König-Wilhelm-Stollen is a natural monument and the Obere Feldbergstollen near Wennigsen is an FFH area.
