How Deep Can You Dig Underground?
While it may seem like a fantasy, tunneling through the Earth’s surface is not impossible. But the question is how far can you go before it becomes too dangerous?
Throughout history, many attempts have been made to dig deep into the planet’s crust and reach levels that nobody has ever reached before. Some have been successful, while others have failed.
The deepest hole ever drilled is the Kola Superdeep Borehole in Russia, which is 12.2 kilometers (40,230 feet) below the surface of the Earth. But it wasn’t enough to get anywhere near the Earth’s core.
That’s because the temperatures and pressures are so high that it would be impossible for humans to live at those depths, even if they could keep shafts open.
However, there are still some places where digging is possible underground if you know what to look for. First, you’ll need to be sure that there are no utilities buried under the area you’re digging.
For example, cable and telephone lines that are buried in conduits should not be dug down to the surface. Similarly, water and electrical lines should not be dug down below 900mm (3 feet).
You’ll also need to verify that there are no other utilities, such as gas pipelines, under the surface before you start digging. This is particularly important for natural gas, which can be extremely volatile and can cause explosions if a pipe gets ignited.
A CT scan is a valuable tool for finding buried utility lines, as it will pinpoint the location of the line and any other hidden utilities under the area you’re working in. It can be expensive, but it will save you time and money in the long run.
Other utilities that can be buried underground include railway lines, telecom cables and water pipes. If you’re digging in these areas, it’s essential to use a CT scanner before you begin.
In the future, scientists will probably try to drill into the mantle, which is the layer that sits atop the Earth’s crust. It’s home to molten rock, which can heat up to more than 500 degrees Fahrenheit.
It would take a lot of energy and time to drill down into the mantle. But scientists have never stopped trying to make that happen.
The Soviets started digging the Kola Superdeep Borehole in 1970 and it ended up becoming the world’s deepest hole – at 7.5 miles. But the 356 degrees Fahrenheit temperature at that depth made it difficult to continue drilling.
There are also a number of other deep holes around the globe, including those from oil companies. One from Lone Star, for instance, reached 31,400 feet below the ground in Oklahoma.
That’s a pretty impressive feat, and it’s certainly something that should be proud of. But it isn’t the furthest any human has gotten, because there are still thousands of miles of molten rock between us and the center of the Earth.
But if you can ever hope to dig down to the center of the Earth, it would be one of the most amazing things to ever happen.
