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 "Well to Hell", also known as the "Siberian hell sounds", is an urban legend regarding a putative borehole in the Siberian region of Russia, which was purportedly drilled so deep that it broke through into Hell. It was first attested in English as a 1989 broadcast by an American domestic TV broadcaster, the Trinity Broadcasting Network. [1]
Boring is drilling a hole, tunnel, or well in the Earth. It is used for various applications in geology, agriculture, hydrology, civil engineering, and mineral exploration. Today, most Earth drilling serves one of the following purposes: return samples of the soil and/or rock through which the drill passes; access rocks from which material can ...
At least until you pass through the center. We can imagine what it's like to fall through the Earth, but you still don't want to fall into a black hole. The good news?
Riser-less drilling uses seawater as its primary drilling fluid, which is pumped down through the drill pipe. This cleans and cools the drill bit and lifts cuttings out of the hole, piling them in a cone around the hole. [3] Japan's new drillship, the Chikyu, uses a riser for drilling. The riser system includes an outer casing that surrounds ...
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 ...
Separating the planet’s rocky crust and the molten outer core, the mantle makes up 70 percent of the Earth’s mass and 84 percent of its volume. But despite its outsized influence on the planet ...
