Underground development and tunnel blasting made simple

eDev™ II Electronic Blasting System makes easy work of underground development and tunnel blasting. Advance rates in challenging conditions and reduced overbreak can be achieved with the accurate and flexible electronic timing system. Blasts are tied-in and fired faster, reducing the time your crews spend at the face. Whether you are operating with soft or abrasive rock, we have a wire option to suit your needs.

Features and Benefits

eDevii_DetailSolutionsPage_Widget1

Efficient operations with Precision timing

  • Increase tunnel advance rates by up to 25% compared to non-electric detonators
  • Reduce costs by minimising tunnel overbreak by up to 5%
  • Programmable detonators at one-millisecond intervals, removing the need to stock a whole range of delays
  • At-face testability, simple hookup with load-by-numbers and quick programming time
