Grandes Grottes du Monde Ceci est une base de données des grottes les plus profondes et les plus longues de la planète. Elle est disponible pour le moment sous la forme de 3 listes, une triée par profondeur (plus de 300m), une autre triée par longueur (plus de 3kms), la dernière classée par pays.


The World's deepest mine From ancient times to 1989, the South African mines produced more than 40% of all the gold that had ever been mined. In 1970 South African gold production was 1000 tonnes, then more than 70% of the output of the non-Communist world. South Africa is still the world's largest producer, by far. It has the world's deepest mine, 3585 m below surface at the East Rand mine. The Freegold mine, owned by Anglo American, was until recently the world's most productive gold mine at 115 tonnes a year; and Driefontein Consolidated has produced more than any other gold mine, at 2292 tonnes.
World's deepest shaft for gold mine The deepest single-drop mining shaft in the world has been sunk at the South Deep gold mine, owned and operated by Western Areas Gold Mining Company (Johannesburg, South Africa), located in Westonaria, Gauteng Province, South Africa. The shaft, with a depth of 2991.45 metres below the collar, has taken almost seven years of sinking.
The deepest mine to be dug into the earth? The deepest mine in this region is currently Western Deep mine, a network of tunnels which penetrates 3.5 km into the Earth crust. But technology is constantly improving and the South mine is currently being deepened to 4.1km. The Western Ultra Deep Levels, affectionately known as 'Wuddles', is planned to go down 5km in the next few years.
