2023年10月20日 · The Kola Superdeep Borehole in Russia is the deepest hole in the world. It's deeper than the Mariana Trench and deeper than Mt. Everest is tall. Hidden in an abandoned drill site among rotting wood and sheets of scrap metal (remains of the derrick and housing that once stood in Russia) sits a small, unassuming, heavy-duty maintenance hole cover secured into place with a dozen large, rusting bolts.

The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1] It is the result of a scientific drilling effort to penetrate as deeply as ...
