Speaker: The most dangerous thing I've ever done in a mine. Taking down loose ground in front of us. Like when you drill and blast around, bush could be sixteen-feet wide. Ah, twelve to fourteen-feet high. And then you go and muck it out. Then there's loose ground above you. Interviewer: Oh my gosh. Speaker: And you have to get that down. Interviewer: How? Speaker: Well you muck it and then you rock bolt it. Y-- you muck and you rock bolt. And you screen. And you can even shot creek, where you spray cement up into the screening. There's all kinds of ways of doing it now. But anyway it's ah- and you can timber it.
