Situational Awareness
Situational Awareness (SA) is being aware of what is
happening around you and understanding how
information, events, and your own actions will impact
your goals and objectives, both now and in the near
future. Lack of SA is one of the primary factors in
accidents attributed to Human Error.

Situational Awareness
Increased technology does not necessarily improve
SA, in fact the effect can be quite the opposite
It’s Happening in Mining
•Fleet Management Systems - loading efficiencies, KPI’s
•Machine Guidance - floor elevation
•Arm Geometry Systems - precision bucket placement
•Payload Monitoring - maximize tonnage in truck, avoid warranty violations
•PLCs - monitoring machine performance
•Proximity Detection - equipment proximity warnings
•Fatigue Monitoring - evaluating the wakefulness of the operator
•Cameras - 360 views to observe surroundings
•Shovel Tooth Detection - monitor and alert for possible missing teeth
•…

Fleet Management
– Incremental truck loading payload, material types, dump locations, eta of next
truck, delays, downs, and operating statuses, messaging, shift production KPIs
Machine Guidance
– Track elevation, design elevation, cut/fill recommendations, pitch and roll,
load blend calculations, automated dig block reconciliation…
Bucket Positioning
– Arm geometry calculations, graphical depiction, cut/fill recommendations,
automated dig block reconciliation
Proximity Awareness
– Position, status, and direction of other equipment, proximity alerts, hazards
and exclusion zones

Key Situational Concepts
1. Making Sure Operator Doesn’t feel “Out-of-the-Loop”
Must know the state of the software, that it is up to date and displaying correct
information
2. Mode Awareness – Understanding
Ensuring the operator understands why the system is doing what it’s doing
3. Decision Support
Ensuring the operator is using the system for adequate decision making. System
should boost decision making effectiveness by providing necessary information

Conclusion
•
Wenco designs GUIs to support the ability of shovel operators to handle complex
and rapidly changing situations in which informed decisions need to be made
under tight time constraints
•
This involves far more than merely being aware of numerous pieces of data
•
Operators must understand integrated meaning of what they are perceiving in
light of their goals
•
Situational Awareness empowers operators to safely and efficiently move material
within the mine’s operating guidelines and towards the goals of the company.
