Electronic Delay Detonator
Product Description
The AXXIS Silver electronic initiation system is the latest expansion of AXXIS technology. The AXXIS Silver electronic initiation system incorporates numerous handling, performance, and safety improvements built upon the highly successful AXXIS GII system. AXXIS Silver is a cost effective solution for users wanting to upgrade from the limitations and results of non-electric initiation to the flexibility and added blast performance realized by electronic initiation.
The AXXIS Silver electronic initiation system is comprised of four components:
- AXXIS Silver Electronic Delay Detonator (EDD)
- AXXIS Silver Logger
- AXXIS Silver Blasting Box
- BLASTMAP blast design software
Application
The AXXIS Silver electronic initiation system is designed for use in most general and specialized mining, quarrying, and construction blasting applications on the surface or underground. The AXXIS Silver electronic initiation system passes ARP 1717-1: The South African National Standard for the design and approval of EDD initiation systems for mining and civil applications.
Primary Benefits
The AXXIS Silver system is designed for high safety and security levels yet remains uncomplicated. The system is designed for blast crew ease of use as there is minimal menu driven activity to set up a blast.
EDDs safety includes dual capacitors that split the system into two. The logic capacitor is used to communicate and test the detonator and does not have enough storing energy to fire the fuse head. The firing capacitor is only used for firing. The logic capacitor has an internal shunt that when commanded switches gates from logic mode to firing mode. Only in firing mode is the firing capacitor then calibrated and charged for blasting.
The AXXIS Silver system utilises dual voltage for detonator logging and testing at low voltage. Error testing is reported by exemption thus considerably speeding up the testing and blasting process at the firing point. It takes less then two minutes to finalize a blast for firing regardless of the number of detonators.
AXXIS Silver Electronic Delay Detonator performance features include a non-volatile detonator memory. Detonators are programmed and tested during logging by writing the desired firing times and log sequence number into each detonators memory. Once detonators are programmed during logging there is no need to re-programme on powering up again. The detonator history is recorded permanently to the detonator memory making it ideal for track and trace.
AXXIS Silver EDDs have engineered copper cladded steel cables that have excellent resistant to damage and cut offs due to a balanced combination of tensile, elongation, and abrasion resistance. This results in a very low rate of misfire occurrence even under demanding hole loading conditions.

Guidelines for Use
AXXIS Silver electronic delay detonators may only be programmed, tested, and fired with AXXIS Silver Loggers and AXXIS Silver Blasting Boxes. Do not attempt to program, test, or fire AXXIS Silver EDDs with other blasting equipment. Never mix electronic delay detonators and/or components from different manufacturers.
AXXIS Silver Loggers and Blasting Boxes need to be calibrated and serviced by BME qualified personnel or providers every 2 years.
Always use AXXIS harness wire to tie-in blasts. Do not substitute similar looking harness wire as the performance specifications may not be the same.
Although BME AXXIS Silver cables are engineered and constructed for challenging work environments, care should still be exercised when loading and stemming to avoid cutting or damaging downlines.
Ground Temperature
This product may be used in ground temperatures from -40°C to a maximum of +80°C. If the application requires use outside of this temperature range please contact a BME Technical Representative for additional guidance.
Reactive Ground
Reactive ground is typically characterised by the presence of sulphide mineralization. If the application requires use in known reactive ground, or in untested sulphide bearing ground, please contact a BME Technical Representative for additional guidance.
Sleep-Time
The recommended maximum sleep time is 21 days. Sleep time is dependent on factors such as hole depth, explosive column type, and ground water conditions. If the application requires longer in-hole sleep time, please consult with a BME Technical Representative for guidance.
Storage
The storage life for AXXIS Silver EDDs is 60 months under good storage conditions. Please consult with a BME Technical Representative for site specific storage life guidance.
Safe Use
- Never fight explosive fires.
- Refer to Safety Data Sheet (SDS) for first aid.
- All explosives must be transported and stored in accordance to relevant regulations.
