I'm a mining engineer and have also worked as a Jumbo Operator but never worked on a civil project or with a TBM. Have you always been on projects that use TBMs or did you start your career using things like Jumbos and road headers and work your way up.

Also, what is the method of installing ground support? I'd guess you use concrete forms but does the TBM have a method of bolting them in or do you use a seperate machine to place and bolt?

Cheers for the response! Sounds great, there are two underground mining machines I've always wanted to see operate in real life, a TBM and a continuous Longwall miner.
