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]
This hard-to-find rusty cap in the ruins of a building in Russia's Kola Peninsula. As the race in space was winding down, soviet scientists turned inwards. You'd never guess that this is the site ...

The mine operation was interrupted in the 1990s at a depth of 340 m (1,120 ft) after the pit bottom became flooded, but resumed later.
The temperature deep within was 1,000 °C (1,800 °F), heat from a chamber of fire from which screaming could be heard. The Soviet Union had, in fact, drilled a hole more than 12 km (7.5 miles) deep, the Kola Superdeep Borehole , located not in Siberia but on the Kola Peninsula , which shares borders with Norway and Finland .
This massive sinkhole measuring 131 feet wide recently opened up about two miles away from a Russian mine. First, flooding stopped operations at the mine about a 1,000 miles east of Moscow.
Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and obtained a large sample ...

Since 2013, the project has set five records for drilling wells with the deepest depths in the world. In April 2015, the O-14 production well was drilled, with length of 13.5 kilometers (44,000 ft), in April 2014 the Z-40 well was completed with a length of 13 kilometers (43,000 ft), in April and June 2013 - the Z-43 and Z-42 wells 12.45 ...
