3. Questions
MineWare
Office
Installations
MineWare provides monitoring system for:Electric rope shovelsHydraulic excavators (face shovels / back-hoes)Draglines
AIMS:
� Provide operators with real-
time in-truck payload
feedback to better control
loading process
� Provide system to monitor
truck on-board weighing
systems
� Work on electric and
hydraulic machines
� Stay within CAT 10/10/20
rule
Technology 1: Loader Payload Management
Optimum Truck
Payload
Reduce Opportunity
Cost, avoid at-face dumping
due to overloads
Maximise Circuit
Productivity
Reduce Truck bunching/ queuing
Reduce Truck and Road
Maintenance Cost
(10/10/20)
Potential to reduce # of
trucks
Reduced spillage from
overloads
Argus Loader Based Payload Benefits
Increase average truck
payload, decrease variability
= more production +
less overloads
Why Loader Based Payload?
Truck systems not as accurate while loading
Truck payloads at point of load Vs second gear reweigh
• Its real-time!
• Continued calibration of trucks is
difficult
• Some trucks have no weighing
system
• Most accurate truck weighing
occurs on ‘second gear reweigh’
Argus Shovel Monitor
The approach: technology and simple feedback:
New Truck Arrives
RFID system
determines Truck ID
Capacity of truck
provided to operator
Argus payload system
calculates load for
each pass
Operator provided real-time
‘remaining tonnes’ to full load
Truck loaded
correctly and
dispatched
Visual Feedback
during loading
to operator
AIM:
� Provide a simple, effective,
low-cost system for real-
time monitoring of plan
compliance for loaders
Technology 2: Machine Terrain Mapping
BENEFITS:
� Real-time feedback to operators on
compliance to excavation design =
better execution
� Ability to engineers to easily monitor
excavation progress and forecast
� Basic calculations of volumes
� Visually represent data such as
production rates, operator techniques
� All done with existing sensors /
processors
How it works:
Uses real-time knowledge of track & teeth positions to generate a real-time excavation map. This is then compared to design
Misfire Safety Marker
Colour Coded Compliance to Plan
Indicators
Track Machine Position Sequence per Plan
� Better data replay abilities
� Capability to calculate time to end of strip/design based on
historical rates
� Sharing maps in real-time between machines (inc. dozers
and other mobile equipment)
� Augment maps where other data sources available – i.e.
lydar, drones, scanners, etc. Export to planning packages
� Look at estimating face shape (stability), stand-off distance
guidance, and incorporating excavation ‘technique’
guidance.
