상표 최고의 러닝 경로

이 수역은 아마도 인공적으로 만들어진 것(참조 'Alte Thöse')일지라도, 자연이 이곳을 많이 되찾았기 때문에 잠시 멈춰 감상할 가치가 있습니다. Wathlingen과 Hänigsen 사이의 숲에 머물기 위해, @Watho96이 폐석 더미 옆의 가장 직접적인 경로에 대한 하이라이트 [www.komoot.com/de-de/highlight/4791781?ref=whd]에서 정확하게 언급했듯이, 다른 선택지가 많지 않습니다.

레이싱 자전거가 없다면 L311보다 확실히 더 나은 길입니다. ...L311도 현재는 재미가 없지만...

The Riedel potash plant is a former potash mine near Hänigsen. It was the world's deepest mine for potash salt. The Riedel shaft was sunk between 1905 and 1908 (770 m). Funding began in 1909. In 1907/08 a mine siding railway was built from Burgdorf via Sorgensen and Weferlingsen to Hänigsen. In 1928 it was temporarily closed. In the years 1937 to 1945 the mine was part of the army ammunition production facility and underground dump, the Hänigsen Army Ammunition Facility. On June 18, 1946, the explosion accident in Hänigsen occurred here. In 1949 the shaft tube received new installations and potash production was resumed. The mine remained in operation until 1997. The production of potash was stopped in 1996 and that of rock salt in 1997. The bottom is at a depth of 1525 meters. Plans for an underground toxic waste dump were scrapped. The 650 and 750 m level probably still contains old weapons waste (detonators, grenades, combat agent Excelsior (10-chloro-9,10-dihydroacridarsin, Blaukreuz) and its precursor merodanoic acid). The rainwater from the site and the heap seepage water (around 10,000 m³/year) is led into the Thöse. The flooding of the mine is scheduled to be completed in 2028. The BUND criticizes this measure. The miners' association, founded in 1908, still exists today.
