POWERED HAULAGE at Northern Star (Pogo) LLC
Concrete boom pump departing mine on road back to highway, going down steep hill, operator heard loud bang from the drive line and began free-wheel. Waiting too long to brake, gained too much speed to slow with air brakes. Operator picked best place by driving off the road at a spot which it crossed ditch and headed back up the hill side.
