On 6 June 1979, the world depth record held by the Bertha Rogers hole in Washita County, Oklahoma, United States, at 9,583 m (31,440 ft) was broken. In 1983, the drill passed 12,000 m (39,000 ft), and drilling was stopped for about a year for numerous scientific and celebratory visits to the site.
Why did they stop digging 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. Following the collapse of the Soviet Union there was no money to fund such projects – and three years later the whole facility was closed down.
Where is deepest hole on Earth?
Humans have since dug longer boreholes, including the 12,289-meter borehole drilled in the Al Shaheen Oil Field in Qatar and the 12,345-meter offshore oil well near the Russian island of Sakhalin. But the hole in Kola remains the deepest.
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.
Who has dug the deepest hole on Earth?
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.
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.
What was found in the deepest man made hole?
The 23 centimetres (9 in) diameter boreholes were drilled by branching from a central hole. The deepest, SG-3, reached 12,262 metres (40,230 ft; 7.619 mi) in 1989, the deepest artificial point on Earth.

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.
Can we drill into Earth’s core?
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.
Where would I end up if I dug a hole through the earth?
Earth is a sphere, so if you start digging in the Northern Hemisphere, then you’ve got to end up in the Southern Hemisphere.
Is it possible to dig a hole through the earth?
The furthest humans have ever gotten is the tip of the Kola Superdeep Borehole in northwestern Russia, which reaches a mere 7.5 miles beneath the ground. Even so, it took almost 25 years and ended when temperatures of over 350 degrees Fahrenheit made drilling impossible.
