Hand Tunneling

Cobbles, boulders, and hard rock are all potentially insurmountable obstacles for modern small diameter tunnel boring machines, but are generally minor impediments to hand tunneling. In fact, hard rock (>200 MPA) is ideal drill and blast hand tunneling conditions, yet extremely difficult to impossible conditions for TBMs below 8' in diameter.

Tunneling into a mountain or hard rock. | Survivalist Forum

Hard rock mining is tough but there are ways to hand dig with the right technique. I lived for a few years in West Cornwal, once the tin mining capital of the world. There the miners dug into solid granite to extract the tin ore and that rock is hard! Where ever possible, they would dig into the softer layer of rock under the granite and undermine.
