Does a mine close in after a time?

[Guest Voldemort]

Will a cave colapse and cave-in if not used?  If a cave is not used or if anybody has not entered the cave for a x amount of time will it just colapse to a rock tile again?

I've seen a few rock tiles that look like it use to be entrance to a cave.  I've been able to prospect it but not sure if a Mine door (rock) is able to let you prospect or not.  I'm kind of looking for info on this to see how abandoned mines work after x amount of time.

Yes, caves collapse eventually, including entrances.

but does a abandoned mine collapse faster then a active one?

I believe so yes, I think the timer is reset whenever someone passes the/a tile. Which is why a single tile "mine" collapses faster, since no one usually enters except animals.

would a mine door act as any kind of support preventing the opening from closing? I have one blocking my terraforming and would put a door on it to stop the crossing so it closes.

Hmm dont know if doors act akin to the support beams. I would assume they dont, but havent been playing for a few.

Doors dont really act as anything other than doors, I had an entrance collapse while a mine door was in place. Mined it out again, made a door with the shards
