Start watching at 3:47 - a swarm of robots injects material into soft rock to harden it before tunneling.
This method must depend on having rock that can sustain small, but not large, tunnels until the hardening material is injected. That is, if the rock is too soft to tunnel through without collapsing, it could collapse on the small robot tunnels also. I assume such conditions are common, though, making this a viable solution for a lot of tunnel construction.
