What's the world's deepest hole?

2 Answers

After 24 years of digging, and several branches in the hole, the deepest branch of the Kola Superdeep Borehole stopped in 1994 at about 7.5 miles. It's only nine inches in diameter at the bottom. It is still the deepest hole in the world, and the process of drilling was incredibly difficult.
