Autonomy for whom? implications of cyber-physical mining systems for operator work and organisation

This paper examines the implementation of a cyber-physical mining system, the Autonomous Haulage System (AHS), from a work-system perspective. It explores how automation reconfigures the balance between human, technological, and organisational elements, with a focus on operator roles. Drawing on an explorative case study in an open-pit mine, the analysis applies Balance Theory to interpret how work and organisational relations are reshaped as autonomy is redistributed between humans and technology. Findings show that while the AHS contributes to improved safety and predictability, it also introduces greater work-task diversity and responsibility, increased standardisation and bureaucratisation, and reduced social interaction with emerging risks of isolation. Operators remain central to supervision, coordination, and adaptation, but their work becomes more procedural and dependent on organisational structures and formal routines. The study concludes that maintaining balance in cyber-physical mining systems is an ongoing organisational responsibility that relies on social cohesion, mutual trust, and continuous learning. Ultimately, the findings emphasise that the effectiveness of mining automation depends as much on collective engagement and organisational adaptation as on technological performance.
