"The problem-plagued and controversial Snowy 2.0 pumped hydro project has hit yet another snag, with its tunnel boring machine Florence halted once again, this time because it has become wedged in hard rock.The federal government owned Snowy Hydro – already facing massive delays and huge over-runs on costs for the project – announced this week that TBM Florence had halted operations a week ago, on Thursday, May 16.It said TBM Florence had already slowed due to “very hard and abrasive rock” a day earlier, before “the project ceased excavation … on Thursday 16 May due to rock pinching on the machine’s shield.”"

I love this next quote........

"Florence is supposed to be excavating some 16 kms of the headache tunnel but not even completed a single kilometre and has been slowed to a snail’s pace – even after finally restarting after getting bogged for months in soft soil."
