I actually don't dig tunnels that much, I just have a few rooms two to three blocks beneath the surface. When I dig down I usually keep it 1x1x5, I just make siderooms to it if I find something interesting. I usually ignore natural caves, mine tend to link into one huge cave anyways.
Never naturally bumped into a treasure room, however.
