deepest depth ever drilled into the earth
The deepest hole ever drilled by humans (Russians) is the âKola Super deep Boreholeâ, on Kola Peninsula in the North West corner of Russia, located near Finlandâ. Russian scientists had to invent new ways of drilling, due to the depth of that area. A number of bore holes were drilled by branching from a central hole. The bore hole which reached 12,262 meters (40,230 ft) in 1989 is the deepest hole ever drilled, and the deepest artificial point on the earth.
