mining entrance

What happens to the inside of a minning shaft when the mine entrace is destroyed?
i know there were pics in hob and the timing of this thread could be a sensitive issue so feel free to close or delete any derailment.
just woundering if the inside remains intack if the entrace is destroyed or what would happen to a char if left inside while the entrance was destroyed.
The question has been on my mind for a while, don't like the timing.
