Can tunnels collapse?

[Molchita]

Also how wide/high can one mine underground until it starts to become unstable? Also sometimes I see the stone walls shifting. Is that from rain? 'u'; Since it seems to only happen when it rains. Sorry if this has been asked before!

If you're mining where there are layers of rock above your head, theoretically it appears to be almost anything goes. If you're mining in dirt, there's always the danger that too much "weight" on top may cause a collapse, or that taking out the wrong dirt block may cause a chain collapse from loss of block-structural integrity (dirt cave ceilings are especially prone to this). And of course if you're within rock but are mining out ores, you may cause a mineshaft-like collapse if you take out iron ore that was supporting sand/dirt above it etc.

No clue what you mean. I've never seen stone walls shift, except from mining itself. Because of the way the textures and heightmaps are drawn, when you remove a block of rock, ore, whatever, sometimes those things around the removed piece "shift" - I assume it's to prevent the terrain's odd original shapings from forming holes and retain a smooth continuous texturing look, since they aren't purely block-shaped these days. But I dunno.

Oh lordie. ;u; Well, I am at bedrock. A made a hatch inside my "country house" and then I mined straight down until so. Built a decently sized room for storage, forges, cement mixers, etc. Then I started on a castle-like base down the street so I thought "hey since I need lots of rocks, I might as well make a tunnel connecting the two so I don't have to run about". What scares me is having to mine upward and then once I get to the surface, the tunnel will immediately collapse. I guess one won't know until they try it! 'u'

Oh....I've done that sort of thing many times, so I wouldn't have to run on the surface. :) Once I ran a horizontal tunnel that took more than 10 minutes (real time) just for my chr. to run from one end to the other. It's fine.

It may, however, cause structural integrity (SI) issues with any structures/parts of structures on the surface directly above the tunnel/caverns. By that I mean the syndrome of placing blocks on a building and they refuse to "stick" or placing a block causes a weird partial collapse when block SI means it shouldn't. I find that symptom to be rather inconsistent and unpredictable tho. I've dug many caverns/tunnels under structures and had above-ground structure SI still be fine "forever", but it's a bit of a gamble. That's a bug that's been around a long time.

Oh alrighty! I shall keep that in mind. :D Do the wooden beams work for caves/tunnels or is it housing only?
Also thinking of throwing a mini bike down there so I can easily get around faster (going to mine a circular room in each corner wide enough to turn the bike around if needed).

No magic at all. Made tunnel under Navezgane looking like a "H" connecting 2x NS and 1X EW.

But be carefull, minibike in tunnels make it cheaters very easy to look under the map.
a 1x2 Tunnel is enough but if you get of the bike you fall through the world. And you can watch all the driving way along under the Map.

Perfect for minibike i would say is a 2x3 or 3x3 Tunnel, but sure much work.

Oh, god, that's scary. ;u; I shall keep that in mind. I wonder if maybe putting some wood flooring may help? I'll have to see.

so far from what i have read every thing has a horizontal max load but no vertical limit.
