occurred

Serious injury: A lost time injury that results in the injured person being
disabled for a period of two weeks or more.

Minor injury: A lost time injury that results in the injured person being
disabled for a period of less than two weeks

Incidence rate: The number of lost time injuries per 1000 employees for a
12 month period

Fatal injury incidence rate: The number of fatal injuries per 1000 employees
for a 12 month period

Lost time injury frequency rate (LTIFR): The number of lost time injuries per
million hours worked

Fatal accidents 2007-08

A front-end loader (bogger) operator died in an
underground nickel mine when the bogger he was
operating went over the edge on a stope and landed on its
roof on the stope floor some 15 metres below. He was
backfilling the stope with cemented rock fill. It appears that
there was no bund wall across the drive at the edge of the
stope.

Fatal accidents 2007-08 continued

A haul truck driver suffered fatal injuries at a surface gold
mine when the loaded haul truck he was driving struck the
rear side of a stationary bulldozer after the tyres on the left
side of the truck ‘dug in’ as he was turning on a waste
dump. He had been driving on a down-grade to the tipping
site and was turning the truck before reversing to the
dumping position. The bulldozer was at the tipping site to
push material and keep the tip-head in good condition.
