Boulders from the cave-in.

[LaserSaysPew]

Can I do anything with them? Can't mine or lift, rmb doesn't give any options.. Are they just a decoration?

it may cause more cave ins though....dunno if thats a thing or not...im not a miner...so just what i hear from our miners

Destroying boulders does not cause cave ins. However, mining with boulders around has an increased chance of a cave in. From what I remember even supports won't protect you from a cave in when there are boulders present (which may result in double fun when a falling boulder destroys a support beam). So if you want to continue mining in this area you better remove the boulders first.
