  3. Definitions • Lost time injury (LTI): A work injury that results in an absence from work for at least one full day or shift any time after the day or shift on which the injury 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

  4. Definitions continued • Duration rate: The average number of workdays lost per injury • Injury index: The number of workdays lost per million hours worked • Serious injury frequency rate: The number of serious injuries per million hours worked • Metalliferous mines: All mines other than coal mines are classed as metalliferous mines • NOC: Not otherwise classified

  5. Statistical summary for 2007-08 • There were two fatal accidents • There were 435 lost time injuries, 25 less than the previous year (460 injuries) • There was an average workforce of 66,183 employees, an increase of 9% over the previous year (60,861 employees)

  6. Statistical summary for 2007-08 continued • The overall lost time injury duration rate improved by 1%, falling from 20.4 to 20.2 • The overall lost time injury frequency rate improved by 14%, falling from 3.7 to 3.2 • The overall injury index improved by 13%, down from 75 to 65

  7. Statistical summary for 2007-08 continued • Serious injuries in the mining industry totalled 331, which is 17 less than for 2006–07 • The overall serious injury frequency rate improved by 11%, falling from 2.8 to 2.5

  8. Statistical summary for 2007-08 continued • Lost time injury frequency rates by sector: • Gold – improved by 26%, falling from 4.3 to 3.2 • Iron ore – improved by 10%, falling from 2.0 to 1.8 • Bauxite and alumina – improved by 7%, falling from 4.1 to 3.8 • Nickel – improved by 8%, falling from 2.5 to 2.3

  9. 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.

  10. 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.
