Mobile equipment issues What needs attention? 2

Contact and collisions Vehicle over edges Run-away vehicles Fit-for-purpose What can go wrong? 3

Is mobile equipment getting away from us? 4

Contact and collisions Size, weight and power of mobile machinery used in mining operations present significant hazards to people and equipment in area of operation In particular, an operator has restricted view of surroundings Resources: Mines Safety Matters pamphlet Working near large mobile equipment Mines Safety SIR No. 176 Light vehicle collides with stationary loader Mines Safety SIR No. 152 Haul truck and light vehicle collision Mines Safety SIR No. 132 Mine haul truck runs over a light vehicle following a driver change 5

Mines Safety Significant Incident Report No

Effective controls Segregation of vehicles, work groups and pedestrians Route segregation Proximity devices and cameras What else? 8

What can cause a vehicle to go over the edge? Too close to edge Too steep Too fast Ground instability Poor road design Poor road maintenance What else? Resources: Mines Safety Matters pamphlet Working near large mobile equipment 9

10

Is anything missing from this dump zone? 11

Question time How does your mine prevent vehicles going over an edge? 12

Effective controls Large windrows Effective back stop Edge preparation (dozers) Dump short Paddock dumping 13

What can cause run-aways? Not applying park-brake Vehicles left running and unattended Parking on slopes Misuse or lack of chocks or bunds Excessive speed Loss of traction Resources Mines Safety Bulletin No. 106 Loss of control of service vehicles on declines in underground mines Mines Safety Bulletin No. 81 Unattended vehicles rolling away 14

15

What about your site? What park-up procedures are in place? What procedures are there to manage a run-away? 16

What precautions would be required for this road train if it was on your mine site? 17

Effective controls Run-aways Parking – spoon drain or mound Ramp park-up procedure (turn into windrow or wall) Lock-off or limit available gears Speed limiters, engine braking Run-off sand trap 18

Is it fit-for-purpose? On-road versus off-road mobile equipment Braking systems Engine braking and retardation Gear selection and transmission (manual and automatic) Load capability Resources: Mines Safety Bulletin No. 106 Loss of control of service vehicles on declines in underground mines 19

20 Question: How will it perform on a decline?

21 Answer: Possibly not very well! Do a detailed risk assessment.

Question time What is fit-for-purpose? Why is fit-for-purpose important? Do you check the design criteria? Do you risk assess for mine conditions? 22
