Summary
This paper addresses the critical challenge of cognitive overload in mining operations, where technology-centric interfaces often exceed human processing capabilities, leading to errors, safety incidents, and revenue loss. The authors argue that many accidents attributed to "human error" are actually caused by system designs that fail to support Situation Awareness (SA). The study aims to demonstrate how applying a scientific, user-centered design methodology can transform confusing shovel operator interfaces into tools that enhance SA, reduce costs, and improve safety. The research employs Situation Awareness-Oriented Design (SAOD), a three-phase methodology comprising requirements analysis, design, and evaluation. The first phase utilized Goal-Directed Task Analysis (GDTA) to identify operator information requirements. This involved knowledge elicitation sessions with ten electric rope shovel operators, including on-the-job observations and interviews, alongside an environmental analysis of cab constraints. The second phase applied fifty specific SAOD design principles to create a user interface that integrates data to support comprehension and projection, rather than just perception. The third phase involved evaluating the design through user reviews with four operators and two supervisors, using usability surveys and Likert-scale ratings. The resulting interface features integrated displays, such as virtual maps with proximity sensor overlays and multi-view cameras, designed to prevent collisions, detect lost shovel teeth, and minimize the routing of valuable ore to waste streams. Specific design elements include pre-populated truck destinations to prevent errors, salient cues for material identification, and haptic feedback for collision avoidance. Evaluation results indicated high user satisfaction; all participants rated the interface six or above on a seven-point scale regarding ease of understanding, memorability of information location, job facilitation, and hazard elimination. Operators described the design as "user-friendly" and noted it provided a higher level of safety and greater awareness of hazards. The study concludes that implementing SAOD principles in mining interfaces can significantly improve operator performance and safety by aligning system design with human cognitive models. The authors suggest that this approach, validated through preliminary user feedback, offers a strong foundation for reducing operational costs and errors. They recommend further testing with simulated or operational tasks to validate performance metrics and propose expanding the SAOD methodology to other mining domains, such as dispatch control, maintenance, and drilling, to address the complex coordination required in modern mining operations.
