DAVEYTRONIC SYSTEM – Recap
Electronic system value?
A new-generation detonators offering new features never
achieved with conventional:
• Vibration control
• Performances in accuracy timing made it possible to eliminate
overlap and simultaneous detonation
• Fragmentation control
• Optimized sequences can be determined in the light of geological
factors and blast parameters : drilling, loading, blasting
• Safety
• Resistance to application conditions
• Reliability

1 st Case study : Conversion from 2 pass overburden to
cast to place at Simplot Phosphates
Mr Cassidy Mc Allister study: The Original Operation
- The original operation was performed with 3 passes of 21m the
higher cover, 12m the lower cover and in the end the phosphate.
- Each Passes included a drill and blast followed by truck and shovel
removal.
- The pit width was 100 m and the cast to place was around 7%.

1 st Case study : Conversion from 2 pass
overburden to Cast blasting at Simplot Phosphates
Mr Cassidy Mc Allister study: The step of the conversion
1- Study the mechanics of the overburden movement using the DMC model
2- Validate the model in the field for each layer.
3- Applied the model for the cast in place using the two layer at the same time.
4- Validate the model with pyrotechnical initiation
5- Using the same blast with electronic system.

- Better controle of the shot
- The increasing of the power

- Better shot rock for the dozers
and the pad preparation for the
dragline, drill ramp and drill
pad.
- Shorter a haul distance by
Compacting the mine plan
- Speed Access to the ore body

3 rd Case study : Dilution
Dilution of Ore with Waste – identified source of value loss
Electronic timing flexibility enables independent muckpile displacement
design – simultaneous displacement of blocks with different vectors
3 rd Party Surface Iron Ore Mine - Australia
28

Value Creation from Engineering – Dilution
Hypothetical Example : Value Penalty
Copper Mine → Assume one 240t truck (ore) misdirected to waste dump
→ Assume grade, rec., Cu $3.34/lb,
→ Assume Burden/Spacing/Bench height/Rock Density
One truck implies a loss of US$9.000
One blast hole compromises 6.5 trucks ( US$60.000)
Possible dilution scenario involving 5 holes → US$300.000
A truck of waste that is misdirected to the process plant will also impact negatively
• Loss of the revenue from the ore truck that is displaced
• Loss of the cost of processing for no return
• Loss of values that are “dragged” out of the plant as tails
At an assumed cost of US$25 per detonator – a misdirected truck is akin to 360
detonators of purchasing power
