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 Xiaozhai Tiankeng is 626 meters (2,054 feet) long, 537 meters (1,762 feet) wide, and between 511 and 662 meters (1,677 and 2,172 ft) deep, with vertical walls. Its volume is 119,349,000 m³ and the area of its opening is 274,000 m 2. This material has been dissolved and carried away by the river.
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 ...
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 ...
The system became the deepest in the world with its overall vertical range of about 2,500 m (8,200 ft) (measuring to the borehole water-bearing horizon) or even 2,700 m (8,900 ft) (measuring to the deepest reported submarine discharge points).
