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 AwarenessIncreased 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• …

– 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 Concepts1. 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 – UnderstandingEnsuring the operator understands why the system is doing what it’s doing

3. Decision SupportEnsuring the operator is using the system for adequate decision making. System should boost decision making effectiveness by providing necessary information

Out of The Loop

• Colour coded signals for core inputs and outputs• Opacity to indicate confidence of data

Mode Awareness

Current Mode (Status)

One-touch next Status

• Automatically switch between PitNav and standard MDT screen

• Switch based on status and/or GPS speed

Automated Switching

Decision Support

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.
