Once a cave-in has occurred, the rocks that fall increase the odds of a cave-in. Cave-ins do not need a full tile to fall in or an empty tile to fall in. They will very happily land on you, or on unmined tiles, or even on buildings.
From my observation, snaking seems to be entirely safe but this is assuming that there is no human error, which can and will happen.
The other danger is trolls appearing and they will appear in snake tunnels, something not even mine support can prevent.
Essentially, it is best not to mine with anything aside from a miner alt. To preserve the amount of cheese to invest, have the alt wear a helmet so it might survive an accident cave-in. For trolls, make a boulder cage with a 1 tile opening as trolls will not be able to pass through it while you can so when you encounter one, you can sprint over to the cage.
