Mr blue, he was seriously injured but he was flown to Perth hospital and recovered.

Mr blue,

[manniefold]

I'd like to point out that it was not a rock stuck in the gyro, but it was instead a bucket tooth that they were trying to lance out

[minetalk]

No worries mate, thanks for that.

Why did it blow out?

[Safetywearhouse]

Nah he is alright

Flown to Perth hospital with a fractured skull but he lived.

I was there

As they lanced it, the metal tooth started to expand from the heat, but it had no where to expand to. When it let go, it was like a cork popping, all that pressure around and underneath it caused it to take the path of least resistance and it shot up and got him a glancing blow. He was out for a few minutes from what I understand.

Much respect to the man who dived in after the incident. Quick action saves lives.

Thumbs up if you were hoping to see Doctor Crusher from Star Trek TNG

Im a former quarryman, used to drive a dumper and a jaw crusher! bucket teeth coming down from the face are simply DEADLY, im shocked at this vid, but glad the fella survived!

@N2trogen Looks to me just like a yellow railing :P the way the shadow is going over it though, it does indeed give it the "Glowing hot" look.

[gmikoner]

holy shit i can't believe the guy survived.

[beneaththeroses]

@N2trogen i was wondering the EXACT same thing 

[N2trogen]

Is it just my imagination, or is the metal railing just to the left of the scene red hot?

[stockcar4d]

lucky for him, bet there was some serious amounts of paperwork to fill out THAT day

@minetalk : when slicing tramp metal (mannie is likely correct, tooth and/or adapter trapped under pressure in the crusher) the amount of potential energy pent up by the process is enormous.

In this case the metal removed by using the magnesium lance allowed the remaining metal, heat compromised, to let fly.

I've done this many times, on various crushers and they're all nerve wracking due to the unfortunately frequent event displayed here. There has to be a better way.
