Where is the deepest man made hole

And even though work in the open-pit mine has ceased, Russia still mines underground in the site. Thanks to the University of Wisconsin, the Amundsen-Scott South Pole Station in Antarctica has 86 cables that reach beneath the ice, supporting 60 digital optical modules that relay data from the depths to the surface above.

And that surface is a long ways away. The modules hang at depths starting at 4, feet all the way down to over 8, feet, or 1. It took seven years to drill holes for the cables, done in the Southern Hemisphere's summer and with a 25,pound hot water hose that melted roughly , gallons of water per hole.

Kola Superdeep Borehole, Russia. Or out. Russia announced that the borehole will be closed down using unique dismantling equipment. Some said it had been partially cemented.

Although the project ultimately failed, the Kola Superdeep Borehole provided scientific insights into the Earth's geology and had been a site of extensive geophysical examinations. Russians claimed that the rock at that depth had been thoroughly fractured and was saturated with water which scientists assumed false, given that the crust 5km down was very dense and rocks should be impermeable. However, they assumed this water came from deep-crust minerals and had been unable to reach the surface.

In addition to that, they reported a large quantity of hydrogen gas flowed out of the hole. The deepest hole within the U. The well was halted because it struck molten sulfur. In funds ran out and the project closed. Where they were digging, the Moho is 16, ft deep, so the team fell far short of their goal. However, valuable core samples were obtained and a lot was learned about deep sea drilling. The deepest hole by far is one on the Kola Peninsula in Russia near Murmansk, referred to as the "Kola well.

After five years, the Kola well had reached 7km about 23,ft. Work continued until the project was abandoned in because the drill became stuck in rock at a little over 12km almost 40,ft or 8 miles deep. The researchers passed through seismic plates and encountered temperatures as high as degrees F. They managed to get down about six miles before they ran out of funds.

Not surprisingly—because the crust is thinner—some deep holes have been bored through the ocean floor. The specialized Japanese drillship Chikyu claims the record for the deepest offshore hole drilled for scientific purposes—about 10, feet almost 2 miles below the sea floor, according to James F. The oil and gas industry also claims some deep holes, on land and offshore. The drilling rig—lost in an explosion in — managed to get some 30, feet below the sea, or about 5 miles. Now, the international team that sponsors the Chikyu is endeavoring to top all previous records.
