Sorry Alex, that is plain wrong and nonsense.
They don't explode. Liquids and solids are highly incompressible.
I have some bunker coal from the Titanic on my desk. Taken 3.8Km down. So far it hasn't exploded.
The literature is full of examples of 600,000 year and older ice core data from samples takes at 3-4 km down.
