Water Management
Notes:
Proficiency Skills
Timely and thorough hotseat handover conducted
Delays selected and mine control forewarned/informed of extended delays
Controls the work area i.e. plans with, and delegates work to the support equipment
Reports under/over trucking
Correct Minestar plan and material files selected when required
Conducts cleanup/bench prep during hang time
Provides feedback/guidance to truck operators when required
Rounds off the start and end corners of bench
When mining a wedge, the low edge is faced up by the dozer before the excavator reaches it
Before each load the excavator is positioned to maximise bucket fill factors
Trucks are positioned to maximise bucket fill and minimise passes
Bucket is only opened far enough to precisely place material in truck tray
Stick out is used to assist material to quickly leave the bucket over the truck
Bucket/stick angle adjustments are made swinging out of the truck, instead of at the bench toe
Not "gardening" or over reaching during normal loading
"Booms up" only enough to utilise "stick out" into the tray
Swing angles <90 degrees (unless on a wide cut/thin seam)
Excavates corners productively
Consistent dig pattern demonstrated
Demonstrates building a safe ramp and safe walking on/off bench practices
Excavates a walk off ramp with the last truck prior to a service/refuelling delay
Takes no half buckets
Shows a productive mindset i.e. is always ready to spot the truck when one arrives
Sump location is surveyed and sediment traps constructed
Demonstrates payload monitoring and management to reduce passes/buckets per truck
Target payload average is monitored and maintained
Truck load is centred/contained
Notes:
Proficiency Knowledge
What is the exclusion zone that exists around powerlines and electrical installations?
What is the location of all emergency stops on machine?
What is an open edge, and what are the berm/bund requirements?
What is a high risk berm/bund and what are the placement and design requirements?
When are documented safety checks and full plant hazard checklists completed?
What action is taken when a misfire or blasting product is observed/suspected in dig face?
In what circumstances can a dozer clean up in the swing radius of the excavator?
Can trucks self spot while top loading?
Emergency procedure for onboard fire was correctly explained/simulated
Use of emergency access/egress systems was correctly explained/simulated
