Also, if you're mining in a straight line, one cave in can completely block the path and lead to chain cave-ins if you try to clear out the new walls it drops and you're unlucky. The further from a cave path that you are, the more valuable supports are.
Sort of. See, if you're mining supportless and you get a cave in, if you clear the exact same set of tiles minus the one that caved in, you get no more cave ins. The tile itself holds the cave in information, not whether or not it has rock. This is also why if you hit a cave in tile, but don't clear that tile (the cave in missed it), you can hit trouble. If you mine past it and ANOTHER cave in fills that cave in tile, you go back to clear and hit the same cave in again.
Prospect tunneling wise it's pretty safe, I have huge issues hitting hardness veins so I can't go far with S12 pick and 74 str on L1. It's mining out larger areas that supports make much less hassle. Also occasionally you'll get overlapping unstable tiles, and I'll drop a wooden support to get me through that part of the tunnel.
