This list of deepest mines includes operational and non-operational mines that are at least 2,224 m (7,297 ft), which is the depth of Krubera Cave, the deepest known natural cave in the world. The depth measurements in this list represent the difference in elevation from the entrance of the mine to the deepest excavated point.
Mponeng is an ultra-deep tabular gold mine in South Africa in the Witwatersrand Basin of the Gauteng Province. [1] Previously known as Western Deep Levels No1 Shaft, the mine began operations in 1986. [2] It is one of the most substantial gold mines in the world in terms of production and magnitude, reaching over 4 kilometres (2.5 mi) below the ...
In 1915, the Morro Velho mine reached a vertical depth of 5,824 feet (1,775 m), which made it the deepest mine in the world. [ 2 ] [ 3 ] The miners continued going deeper, and the mine kept the title of world's deepest until 1928, when the Village Deep mine in South Africa reached a vertical depth of 8,000 feet (2,400 m), exceeding the depth of ...
The mine is the largest human-made excavation, and deepest open-pit mine in the world, [4] [5] which is considered to have produced more copper than any other mine in history – more than 19,000,000 short tons (17,000,000 long tons; 17,000,000 t). [5] The mine is owned by Rio Tinto Group, a British
The mine is near the town of Carletonville in South Africa. At approximately 3.9 kilometers (2.4 mi) deep, it is home to the world's second deepest mining operation, rivalled only by the Mponeng Gold Mine, formerly Western Deep Levels No.1 Shaft. TauTona was temporarily closed in 2018. [2] The mine was one of the three Western Deep Levels mines.
The Homestake Mine was a deep underground gold mine (8,000 feet or 2,438 m) located in Lead, South Dakota. Until it closed in 2002 it was the largest and deepest gold mine in the Western Hemisphere . The mine produced more than forty million troy ounces (43,900,000 oz; 1,240,000 kg) of gold during its lifetime. [1]
In May the global average temperature was 1.52 degrees Celsius above the pre-industrial average, marking the 11th consecutive month where the global average temperature was at least 1.5 degrees ...
The mine, with a depth of 1,600 metres (5,200 ft) in 2019, is Australia's deepest underground gold mine and the deepest trucking mine in the world, with a proposed depth of 2,300 metres (7,500 ft) by 2031. From its discovery to 2019, the mine produced 5.5 million troy ounces (170 t) of gold, at a 2019 equivalent value of A$10 billion. [5]
