eDev™ II - Delivering Solutions
Improvements that matter most to you
Civil Tunnel Blasting

Improved vibration control when blasting close to critical infrastructure.
|
Faster rate of lateral advance
Improved vibration control - Achieve greater advance per round which is particularly important when blasting close to critical infrastructure or surface neighbours.
Operational efficiency– With at-face-testability, the new Load by Numbers technique, single SKU (Stock Keeping Unit) and improved speed of operation, the eDev™ II system offers a new level of operational efficiency to ensure faster drill & blast cycles.
Multiple heading blasting – Improved convenience to blast multiple headings due to increased maximum delay and increased precision of the eDev™ II detonator.
Operational productivity
Uniform fragmentation for easier and efficient muck removal – Accuracy of delays in timing delivers consistent and predictable fragmentation and reduced oversize to allow easy and efficient mucking, ultimately contributing to faster project completion.
Versatility for changing geology – Versatile timing allows changes in blast designs to meet changing geology.
Risk management – improved mine safety
Improved perimeters, over-break, side walls and hanging walls – eDev™ II is designed to fire holes in precise sequence with optimised delays to ensure the release of burden and rock movement with minimal back break. This can significantly improve perimeters, over-break, side walls and hanging walls to reduce the need for ground support and ensure a safer operation
Faster rate of lateral advance
Improved vibration control – Mines can achieve greater advance per round, which is particularly important when blasting close to critical infrastructure or in poor ground conditions.
Operational efficiency – With at-face testability, the new Load by Numbers technique, single SKU (Stock Keeping Unit) and improved speed of operation, eDev™ II offers a new level of operational efficiency.
Multiple heading blasting – Improved convenience to blast multiple headings due to increased maximum delay and increased precision of the eDev™ II detonator.
Operational productivity
Uniform fragmentation – Accuracy of delays in timing delivers consistent and predictable fragmentation and reduced oversize to allow easy and efficient mucking.
Ore/waste separation through control of heave – The timing accuracy of eDev™ II can assist mucking efficiency by separating ore and waste from different parts of the face in a single round.
Versatility for changing geology – Versatile timing allows changes in blast designs to meet changing geology.
Risk management – improved mine safety
Improved perimeters, over-break, side walls and hanging walls – eDev™ II is designed to fire holes in precise sequence with optimised delays to ensure the release of burden and rock movement with minimal back break. This can significantly improve perimeters, over-break, side walls and hanging walls to reduce the need for ground control.
Changing Geology: Figure 1 represents a typical simulated outcome with Long Period detonators resulting in ore dilution. Figure 2 represents an eDev™ demonstration result showing ore/waste separation.
Perimeter Control: Figure 3 represents a typical outcome resulting in overbreak with Long Period detonators. Figure 4 represents an eDev™ demonstration resulting in clearly visible half barrels.
