Blast Boxes
Blast Boxes
AXXIS TITANIUM™ blast boxes are each enclosed in a yellow robust plastic case that is half the size of a GII™ blasting box.
Box control is simple, with double rotary switches for switching a box on, placing it in standby mode to open the communication channels, and firing the blast.
Wireless communications are achieved through two selectable open-band frequency channels (400 MHz and 900 MHz) that can be configured based on the site requirements.
All AXXIS TITANIUM™ blasting boxes are the same, but each one can be configured either as a blaster or as a controller, to accomplish its required function.
The blasters are placed at each blast site and connected to the surface wire harness. No power is supplied to the detonators until the controller arms the system at blasting time.
Up to 200 blasters can be controlled and fired from a single controller.
In large single blasts where more than one blaster is needed, AXXIS™ link sets can be used to hard-wire (link) the boxes.
Each blaster can fire up to 1 000 detonators.
The process for setting up and switching on each blaster is:
Final testing is done on the harness lines, using the AXXIS TITANIUM™ logger, before the harness line is connected to the blaster.
- Only one controller box can be configured per blast. The key logger must be present to authorise the arming and firing of the system.
- On the arming of the system, each blaster powers up its detonators, and testing routines automatically start and continue until firing time.
- Detonators respond by exception, allowing a quick testing time and immediate warnings to the operator through the colour screen on the box and the key logger.
