Let's add an earthquake, asteroid hit, the deluge, finding underground lost city and Norwegian invasion from the north to the list of potential dangers then too :)
Just kidding...They will be fine. It's not as difficult as we all think and those guys know what they are doing. Not all the projects are delayed. I'm not saying it will all go flawlessly but in the same time i don't see any particular to be concerned about. Basically they have to sink a shaft (done hundreds times before) and dig a 20miles worth of industrial grade tunnel.....I know I'm simplifying but come on - considering the team, combined knowledge and experience, and funds (hopefully debt only!) they are more than capable of completing it. And if somebody gets injured - well, it happens everywhere but shouldn't have a major impact on the project as a whole.
