The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1]
The lowest point underground ever reached was 12,262 m (40,230 ft) deep (SG-3 at the Kola Superdeep Borehole, which has since been enclosed). The lowest human-sized point underground is 3,900 m (12,800 ft) [38] below ground at the TauTona Mine, Carletonville, South Africa.
[1] [2] Humans have drilled over 12 kilometers (about 8 miles) in the Sakhalin-I project. [3] In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth. [4]
