How deep is the deepest hole ever?

Answer 1

The deepest man-made borehole in the world is the Kola Superdeep Borehole (Russia, 1989) at 12,262 meters (7.6 miles). The deepest natural ocean depth is about 6.8 miles (11000 meters), in the Marianas Trench near Guam.

Answer 2

The deepest man-made hole in the Earth is located in the Kola Peninsula in northwestern Russia. The depth achieved from the surface was 12,262 meters, roughly 7.5 miles. The 9" bore hole was created by a rotating bit spun by the pumping of drilling mud. Unexpectedly high temperatures caused the stoppage of the drilling in 1994, 24 years after drilling was started. The goal of the Russians was to drill to the Moho, the boundary between the crust and the mantle, but the goal was not reached.

Answer 3

The Kola Superdeep Borehole in Russia holds the record for the deepest hole ever drilled, reaching a depth of about 7.5 miles (12 kilometers). It was drilled for scientific research purposes to study the Earth's crust and mantle.

Answer 4

Answer 5

The deepest point in any ocean is the Mariana Trench (aka Challenger Deep) in the western Pacific Ocean at 11,033 metres deep.

Answer 6

The Kola Superdeep Borehole is a man made hole that is the deepest on earth. In 2007 it reached a depth of 40,230 feet or 12,262 meters. It is located in Russia on the Kola Peninsula.

Answer 7

It would be in Russia on there Kola Peninsula. It is about 40,000 feet deep. They have been drilling since the 1970s.

Answer 8

Ummm.......lets say "why dont u go explore it and tell us?"

Answer 9

The deepest hole drilled into the crust of the earth is 7 miles (12 km.) deep. The hole is on the Kola Peninsula in the USSR
