i-kon SystemThe basic i-kon™ system consists of programmable digital Detonators (Standard and RX for more demanding applications) and control equipment - i-kon™ Logger and Blaster.

Detonators are loaded into holes without assigned delay timing. Timing is assigned during the logging process. The logging process can be done in a number of modes:


a) Log-as-you-go. Once the holes are loaded the Logger is connected to one end of the harness wire and the blast crew walks the pattern attaching each detonator in the correct sequence. As each detonator is attached timing is assigned to that detonator either from a blast design downloaded from SHOTPlus®-i OR on the basis of an auto-increment programmed into the Logger OR manually by entering the delay time on the Logger's key pad.

b) Log-before-you-hook-up. Since the logging process is inherently safe, timings can be assigned to detonators as other holes are being loaded. In this case the harness wire is not used, rather the Logger is connected to the detonator either via a "pigtail" wire or in the case of the new i-kon™connectors and Logger via a probe hole. Timing is assigned either on the basis of an auto-increment programmed into the Logger OR manually by entering the delay time on the Logger's key pad. The harness wire is rolled out later and detonators connected in any order. This mode enables blast crews to utilise what might be idle time if they wait for loading to be completed.

In all cases the Logger also tests the functionality of the detonator during logging.  When the pattern is cleared the harness wire and Logger(s) are connected to the i-kon™ Blaster in a safe location, a final test is conducted, the detonators charged and the fire command can be given.

 

i-kon™ Detonator (Standard)

i-kon™ detonators are fully programmable and have on board digital timing circuits, energy storage enabling them to function independently once the fire signal has been sent and a base charge housed inside a copper/zinc alloy shell to provide appropriate dynamic shock resistance. The legwire are copper-clad steel for tensile strength with a tough polypropylene insulation providing excellent resistance to the abrasive conditions of most mines and quarries. At the surface end of the detonator is a displacement connector which connects quickly and easily to the harness wire. The detonator fits into all conventional boosters. For particularly harsh conditions the i-kon™ RX is recommended

i-kon™ Detonator (RX)

i-kon™ RX detonator is similar to the standard detonator with the exception of more durable TPU insulated wire to convey greater protection against abrasion in high demand applications.

i-kon™ Logger

The i-kon™ Logger is used during hook up to assign the delay sequence and perform testing functions. The Logger reads and stores the unique Detonator ID and required delay time. Each Logger can log up to 200 detonators and up to 24 Loggers can be used on a blast. The Logger by itself cannot initiate the detonator.

i-kon™ Blaster

The Blaster is used to charge, test and control the firing of the detonators. There are four different types of i-kon™ Blasters. The Blaster400 can fire up to 400 detonators on 2 loggers. The Blaster2400S can fire up to 2,400 detonators on 12 Loggers individually and 4,800 detonators when synchronised to another Blaster. Remote Blasters are also available: SURBS (Surface Remote Blasting System) for Open Cut applications and CEBS (Central Blasting System) for Underground applications can fire up to 2,400 detonators.
