The risk of operator fatigue and distraction to mining operations can be significant with the potential for fatality and major equipment damage incidents. In support of improved risk management, the Mine Operations Business Unit at Canadian Natural Resources Limited (CNRL) researched the spectrum of available fatigue management systems, approaches and technologies for implementation on their mine site. Canadian Natural’s comprehensive assessment led to the adoption of the so-called Driver Safety System (DSS) with the result that fatigue events have been reduced by more than 80%! The DSS is a non-intrusive driver monitoring system that can detect both fatigue and distracted driving events experienced by equipment operators, and is used in conjunction with worker education, cab alerts and an effective intervention plan. This presentation also offers the mining industry a quantitative and insightful report on the prevalence of operator fatigue incidents, and dimensions the associated risk management exposure to mining operations.
