New Technologies for Measurement of Operator Fatigue Helping to Deliver Improved Operator Health, Safety and Performance at the Mt Keith Operations

The Mt Keith Mining Alliance operates a fleet of large capacity hydraulic face shovels and more than 40 X 240 t capacity haul trucks to deliver annual production in excess of 40 Mbcm per annum. The Mt Keith Nickel mine is currently operating at a depth to 300 m below surface with a planned final depth of the order of 500 m. As is the case with any large open pit managing the health of the workforce on continuous shift operations is of critical importance to achieving outstanding safety and production outcomes. Fatigue management at Mt Keith is effectively managed by the personnel operating the mining equipment, with assistance and understanding of the management team and supervisors. The program has been driven through the introduction of Fatigue Champions and a comprehensive management plan that includes education, individual health plans and the use of new technologies. Mt Keith has been instrumental in trialling new technology which assists in monitoring fatigue in operations personnel. Insight into these developments is provided in the context of the overall fatigue management plan. The field trials of the OptAlert(TM) system and how it assists in measuring fatigue is explained. The implications for individual operators and the context for a fleet wide approach to fatigue management is also discussed. Mt Keith has recently completed the second phase of trials with the result that this new and exciting technology is being considered for adoption globally across BHP BillitonÆs open pit mining operations.
