A tunnel boring machine (TBM), is used to excavate tunnels with a circular cross-section through a variety of soil and rock strata. They may also be used for micro tunneling. They can be designed to bore through anything from hard rock to sand. Tunnel diameters can range from one metre (3.3 ft) (done with micro-TBMs) to 17.6 metres (58 ft) to date.

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.

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.
