Budget mine support for tunneling

[Grable]

That's kinda mining already. And nothing would prevent from using those to safely mine.

Make it unable to be placed on tiles adjacent to ore? Then you wouldn't be able to tunnel through ore.

I think what you actually proposing here is a way for safe mining with cheap solution. I doubt mining was ever supposed to be safe.

This isn't about mining, it's about tunneling to ore deposits or to another cave so you can actually begin mining ore.

That's kinda mining already. And nothing would prevent from using those to safely mine.

Any tiles to the side of these supports are permanently un-mineable unless you destroy the supports, which instantly causes a cave-in. Tunneling through ore with these would severely reduce ore quantity. Could also severely reduce quality of ore (Or anything.) to the side too.

tl;dr mines look like mines and not caverns

More buildings and item integration for mining would be nice, whatever form it may take.
