Batu Hijau mine in Indonesia ranks among the most productive copper mines in the world, producing 1% of the world’s total supply (Wood Mackenzie).
The workforce at the Batu Hijau mine plays a pivotal role in sustaining this remarkable level of output. From the highest echelons of management to the heart of the pit operations, employees are chosen not only for their skills and experience but also for their dedication and passion. This synergy has given rise to a challenging yet fulfilling work environment, where everyone shares a sense of accomplishment in consistently delivering exceptional performance.
Studies indicate that fatigue significantly contributes to accidents within open-pit mines. Assessments conducted by the National Institute for Occupational Safety and Health show that approximately 65% of haul-truck accidents in open-pit mining can be attributed to fatigue. Additionally, a recent study by the Sustainable Minerals Institute at the University of Queensland highlights that weariness plays a role in around 2.5% of all reported accidents within the local mining sector.
AMMAN, the operator of the Batu Hijau mine, addresses the problem of fatigue management through an innovative approach that blends personal responsibility with advanced technology.
Frontline workers play a crucial role in identifying and reporting indications of fatigue among their colleagues. In these instances, fatigued team members are encouraged to take breaks without facing negative consequences, while vigilant coworkers are acknowledged for their dedication to ensuring the welfare of their fellow team members.
At supervisory and management levels, scheduling and task assignments are continually monitored and adjusted to ensure that changes in the workplace environment do not place undue strain on particular teams or shifts.
Advanced technology provides a solid foundation for the team’s collaborative approach to identifying fatigue. The precise GPS tracking enabled by smart badges worn by key personnel assists in detecting repeated instances of erratic vehicle maneuvers, such as sudden braking and sharp turns. These patterns often signal a lapse in concentration on the part of transport drivers.
The horizontal chain of responsibility model for fatigue management reflects AMMAN’s commitment to engaging all employees in monitoring and decision-making for mine and support-facility operations. In all aspects of production, AMMAN as a prominent mining company in Indonesia will always prioritize employee empowerment.
