    It's actually more common for dudes to tunnel than you'd expect.

        This seems like a good way to die in a cave in? How do you not run out of oxygen? I have so many questions!!

            the ground is porous and oxygen flows in through the earth

            I'm pretty sure this isn't true, but I'm not a dirt scientist. You might get radon gas seeping through the earth though.

                I think it all depends on how much air is flowing through the cave or tunnel (either naturally or with fans) and how many people are in a confined space breathing at any moment. With mining or tunneling you can also hit pockets of methane or other gasses that can be explosive or displace oxygen, but I think that's mostly a hazard in coal mines.
