America might have landed on the moon, but Russia drilled the deepest man-made hole on Earth. Since the early 1960s, scientists have attempted to drill down to the Earth’s mantle. It took 20 years, but Russia drilled down 40,230 feet into the earth, before heat forced work to stop.
Why did they stop digging the Kola Superdeep borehole?
Then it was the turn of the Kola Superdeep Borehole. Drilling was stopped in 1992, when the temperature reached 180C (356F). This was twice what was expected at that depth and drilling deeper was no longer possible.
What was found in the deepest hole on Earth?
Unexpectedly, helium, hydrogen, nitrogen, and even carbon dioxide (from microbes) were found all along the borehole.
- There is no basalt under the continent’s granite. This was a huge surprise. …
- There are fossils in granite 6,700 metres below the surface. How’d that happen?
- Hell is deeper than 12,262 metres.

What was found in the Kola Superdeep borehole?
The Kola Superdeep Borehole was just 9 inches in diameter, but at 40,230 feet (12,262 meters) reigns as the deepest hole. It took almost 20 years to reach that 7.5-mile depth—only half the distance or less to the mantle. Among the more interesting discoveries: microscopic plankton fossils found at four miles down.
What is the deepest a human has been underground?
Now the deepest hole made by humans is the Kola Superdeep Borehole. At 12,000 metres deep (plus a bit) it goes roughly one third of the way through the Earth’s crust. … Not quite as deep as the Kola Borehole. The deepest underground mine is in the order of 3,800 metres.
Why did Russia dig a hole?
Drilling the Kola Superdeep Borehole was, for the most part, purely science-driven. Soviet scientists wanted to learn more about our planet’s outermost layer, called the crust, to understand how that crust has formed and how it evolved.
How deep can you dig into the earth?
Deepest drillings
The Kola Superdeep Borehole on the Kola peninsula of Russia reached 12,262 metres (40,230 ft) and is the deepest penetration of the Earth’s solid surface. The German Continental Deep Drilling Program at 9.1 kilometres (5.7 mi) has shown the earth crust to be mostly porous.
How hot is it 1 mile underground?
Geologists calculate that, for every mile you dig beneath the Earth’s surface, the temperature rises 15º F and the pressure increases simultaneously at a rate of about 7,300 pounds per square inch. Violations of the 15-degrees-per-mile rule are unknown and constitute the notorious forbidden zone.
What would happen if you drilled a hole through the earth?
With such immense speed, you completely overshoot earth’s center. As you travel through the far end of the hole, gravity is now in the opposite direction and slows you down. You are slowed down to zero speed just as you emerge from the hole on the other side of the world.
What would happen if you drilled to the Earth’s core?
The drill would fail at about 40,000 -45,000 feet (12 -14 km). At that depth you could roast a chicken, and it only gets hotter closer to the mantle. Eventually, magma would erupt through the hole. The hole reached 12,262 m (40,230 ft) in 1989.
Has anyone ever dug into mantle?
Drilling To The Mantle Of The Earth : NPR. Drilling To The Mantle Of The Earth Fifty years ago, scientists attempted to drill deep through ocean crust to the Earth’s mantle, an endeavor called “Project Mohole.” That project failed, but scientists are sharpening their drill bits again.
Can you dig a hole to China?
Take a closer look at a globe: China is actually not antipodal to the United States. That would be impossible, since they’re both in the Northern Hemisphere. If you dug a hole from anywhere in the lower 48 states straight through the center of the Earth, you’d actually come out… in the middle of the Indian Ocean.
Where would you end up if you dug straight down?
If you’re a flat-Earther, you’ll eventually break through the bottom of the Earth and just fall straight down into eternal space because that’s how physics work. If you’re a hollow-Earther, you’ll eventually dig into a plesiosaurus nest and be eaten.
Why can’t we drill to the center of the Earth?
It’s the thinnest of three main layers, yet humans have never drilled all the way through it. Then, the mantle makes up a whopping 84% of the planet’s volume. At the inner core, you’d have to drill through solid iron. This would be especially difficult because there’s near-zero gravity at the core.
How deep is core of the earth?
Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles).
How deep has a human gone in the ocean?
It’s been a record-breaking expedition in more ways than one. Vescovo’s trip to the Challenger Deep, at the southern end of the Pacific Ocean’s Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).
