Mining Equipment Performance Evaluation, (Total Available Operation Time …
Mining Equipment Performance Evaluation
Physical Availability (%)
is influenced by
Maintenance Schedules
High or low frequency can increase or decrease availability
Breakdowns and Repairs
Can be caused by mechanical failures or improper usage
Spare Parts Availability
Delays in procuring spare parts can increase downtime
Operator Skill
Incorrect operation may lead to accidents
Age of Equipment
Older machines are more prone to breakdowns
Utilisation of Availability (%)
is influenced by
Operational Efficiency
Efficiency in scheduling or coordination between operators and managers (to avoid available but unused equipment)
Operator Availability
No operators -> equipment went unused
Shift Scheduling
Ensures optimal machine usage
Waiting Times
Delays, e.g. waiting time for materials to load or unload
Fuel or Resource Availability
Productivity (Bcm/Hr)
is influenced by
Machine Capability
Larger or more advanced machines can increase productivity
Operator Skill
Higher skill can increase efficiency
Site Condition
Terrain, weather, and material hardness
Operational Planning
Proper planning of haul routes, loading, and dumping
Maintenance
Well maintained machine tend to perform better and be more productive
Cycle Times
Time taken to load, transport, and dump material
(Total Available Operation Time - Downtime) / Total Available Operation Time) * 100%
Shows how often equipments are in ready-to-operate condition
(Actual Operation Time / Total Available Time) * 100%
Shows how much of the available time the machine is actually in use
(Total Volume of Material Moved / Total Operating Time)
Reflects the output per hour when the machine is operating
