When they excavate, they’ve got to support the rock as they go along, otherwise other people will be in danger. So they are driving in a new tunnel hopefully, in somewhat, shall we say, stable rock.
And these 12 metres that they’re getting into, I don’t know again what is the situation there, but they’re getting probably to the zone of broken rock, and they’ll have to take extreme care so that other tonnes of rocks don’t come down on the other people.
By Battacharya’s estimate, those final tricky metres could be covered within 24 hours. Meanwhile, Kim Beazley is scoring political points. For shame! Have you no decency sir? Etc.
