i-kon™ Logger

The Logger is used on the bench as part of the hook-up process to check the ID number and the status of each detonator. The Logger operates well below the no-fire voltage of the detonator ensuring inherently safe operation on the bench. The delay time for each detonator is stored against the ID number in the memory of the Logger for later programming by the Blaster.

i-kon™ Blaster

The Blaster is used to calibrate, program, arm and fire the i-kon™ detonators via the Loggers. Individual detonators and system integrity are fully verified and displayed to the user before the blast is fired, allowing confident blasting or trouble-shooting to be performed.

There are two different Blasters for small and large blasts (Blaster 400 and Blaster 2400S). Two Blaster 2400S units can be synchronised together to fire 4800 detonators.

The i-kon™ CEBS Remote Blast Box initiates underground blasts from a control location on the surface. It is capable of firing 2400 detonators on 12 loggers.

The CEBS Lock Box connects to the blast controllers computer and is used to control the function of the remote blast box which is located near the blast. The blast can now be fired with full mine clearance of personnel.

The power of the i-kon™ System is SHOTPlus®-i UG, an in house tool developed to provide a seamless front end to a mine’s design and production systems. By integrating directly with the i-kon™ Loggers the blast design process flows into the hook-up design, both speeding up and ensuring the integrity of the process.

SHOTPlus®-i UG can import survey data detailing blasthole coordinates and identifiers, geological boundaries, pit design information and critical design elements. This allows for more accurate initiation designs to be developed, seamlessly incorporating site based systems with Orica technologies. Data upload completes the process, with the ability to document and report the final blasting outcomes and explosive consumption.

Electronic Blasting Systemselectronic Blasting Systems differ from electric and non-electric delay systems in that the delay time is controlled by a programmable integrated circuit, resulting in very precise timing.The accuracy and programmability of electronic detonators allows for blast timing to be tailored to the geometry, geology and unique requirements of any blasting operation to more effectively use explosives energy.

Key Benefits

• The ability to initiate large blasts using unique delays in each blasthole without delay overlap

• Improved blasting efficiency – the same results for reduced input cost

• Finer and more uniform fragmentation

• Increased equipment productivity

• Enhanced safety and security

• Reduced and simplified inventory

Our systems are easy to use, easy to program, and very safe. The detonators are identical in size and output to non-electric detonators. Every detonator has a unique, traceable ID number held on the chip, and printed on the attached tag. They are programmable in millisecond increments and have a high level of protection against accidental initiation by stray or induced currents and electrostatic discharges. The tough, all-weather hardware is intuitive to use and much liked by blasters.

Orica’s i-kon™ Digital Energy Control® System represents Orica’s most sophisticated blast initiation technology available. The extraordinary accuracy, flexibility and safety delivered by the i-kon™ System will allow you to optimise your blast designs like never before. The i-kon™ System is the result of Orica’s ongoing commitment to provide value-added products and services to our Customers that deliver real productivity improvements.

The i-kon™ System has four key integrated components; detonator, logger, blaster, software:

i-kon™ Detonator

The i-kon™ standard detonator is recommended for use in underground mining applications.


delay times Programmable from 0 ms to 15000 ms in 1 ms increments

Wire length (m) Standard: 6, 15, 20, 30, 40, 60

downline wire 0.6 mm steel

Wire tensile strength 25 kgf/250N


Network Tester

The Network Tester is an inherently safe, hand-held testing device used to test for short circuits, leakage and reverse polarity. Most problems can be discovered and corrected by this quick on-pattern testing of the wiring harness.

eDev™ Blaster

The eDev™ Blaster tests, programs, arms and fires the detonators with full two-way communications. The dedicated Blaster is the only means of initiating the eDev™ electronic detonator. When the scanner is docked into the Blaster’s docking station, the information held within it is transferred to the Blaster. At the designated time and location, blasting cables are attached to the box and firing sequence initiated. The eDev™ Blaster has capacity to fire even the largest tunnel rounds.

SHOTPlus®-T is a windows compatible blast design program specifically for tunnelling (which includes mine development). The package contains several standard rounds, but includes powerful routines allowing complex rounds to be designed by applying simple rules to a tunnel face of given geometry. SHOTPlus®-T provides a simple and convenient way to design, analyse and optimise eDev™ blasts.

SHOTPlus®-T is an integral component of the eDev™ System – by interfacing with the eDev™ Scanner the blast design process seamlessly flows into the activities at the face, both speeding up and ensuring the integrity of the process.

Electronic Tunnelling System

The eDev™ system is an Electronic Blasting System specifically designed for tunnelling, providing the accuracy and flexibility of electronic timing at a reasonable price with rapid and easy operations at the tunnel face.

The new “time by numbers” feature and SHOTPlus®-T software allows blasters to operate in a familiar and rapid manner making it possible to achieve benefits such as reduction in inventory logistics and costs, reduced vibration, improved advance rate and overbreak control.

The eDev™ system consists of programmable electronic detonators and hardware to test, program and fire the detonators. The eDev™ detonator will directly initiate detonator Senatel™ packaged explosives and Pentex™ boosters.

eDev™ Detonators

eDev™ detonators have the potential to bring wide-ranging benefits over traditional pyrotechnic detonators and other electronic systems.

Wire length (m) 2, 3, 4, 5, 6, 8

Leg wire Conductor is copper clad steel

Wire tensile strength 20 kgf/200N

eDev™ Scanner

The Scanner is used to passively and safely read the detonator ID from the barcode tag. The ID is associated with an assigned delay time in the scanner’s memory and later transferred to the blaster. “Time by numbers” and auto-increment features combine with SHOTPlus®-T software to allow quick operations at the face.

1 REE is the Effective Energy relative to ANFO at a density of 0.8 g/cc. ANFO has an effective energy of 2.30 MJ/kg. Energies quoted are based on ideal detonation calculations with a 100MPa cut-off pressure. Non-ideal detonation energies are also available on request. These take account of blasthole diameter, rock type and explosive reaction behaviour.

2 VOD will depend on application including explosive density, blasthole diameter, temperature and degree of confinement. The minimum VOD quoted is based on unconfined test firing data.

3 Carbon dioxide is the main greenhouse gas produced. The output is calculated assuming ideal detonation.
