Have you ever thought that a huge mine the size of which exceeds the area of the Moscow subway system can be located right under your feet? Such a mine, which is the largest gypsum minefield in Europe, is situated in the city of Novomoskovsk in the Tula region.
Size of its minefields and chambers just boggles the mind. Gypsum deposit was discovered in Novomoskovsk in 1929.
A mine can be entered through the cage that seems rather undistinguished.
Before the descent every person is supplied with a protective suit, helmet and shoes.
As well as with a separate lamp and oxygen device that has to be used in case of emergency.
Gypsum extraction is carried out at the depth of 130 meters.
