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]
As the race in space was winding down, soviet scientists turned inwards. You'd never guess that this is the site of one of their great achievements. This hard-to-find rusty cap in the ruins of a ...
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 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.
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 ...
Chinese engineers on Thursday broke ground on a new super deep borehole that will burrow far into the Earth’s crust as the country steps up its search for natural resources hidden tens of ...
Krubera-Voronja cave is inhabited by endemic species, including four springtails discovered during the CAVEX Team expedition of 2010: Anurida stereoodorata, Deuteraphorura kruberaensis, Schaefferia profundissima, and Plutomurus ortobalaganensis; the last of these is the deepest terrestrial animal ever found on Earth, living 1,980 metres (6,500 ...
Indeed, while TBJH was initially discovered in 2021, scientists only measured its depth down to 900 feet due to limitations in the echo-sounder technology — which calculates speed based on sound ...
