I was under the impression that the Kora borehole went unfinished because the drill broke due to temperature (7 miles down and you're talking hundreds of degrees C), not the breakup of the Soviet Union.
- alamortsubite 7y agoWhile the article says the time at which drilling was stopped was after the breakup, it gives the reason as the high temperatures encountered. "Then it was the turn of the Kola Superdeep Borehole. Drilling was stopped in 1992, when the temperature reached 180C (356F). This was twice what was expected at that depth and drilling deeper was no longer possible."
