I doubt it's been recorded really - it's notthe sort of question a cave-biologist would ask. There is a SE Asian (Malaysian I think) snake that lives in caves where it preys on bats - but these caves are more horizontal than vertical so distance rather than depth counts.

Snakes are not generally cave-dwellers though they are found in them, either sheltering or by their accidentally falling orbeing washed in.
