The second generation of electronic blasting systems

摘要

8 years after the market introduction of the first commercial electronic detonator DYNA-TRONIC the paper describes a new electronic blasting system Made in Germany. The results of a joint development between Dynamit Nobel and Orica is a unique universal electronic detonator, which is as simple to use as normal non-electric detonators. The delay time or delay interval is not factory preprogrammed and the system is not based on a numbered system like conventional detonators. The miner or blaster decides on site which delay timing he likes to use and is programming the whole blast on site. The new electronic blasting system allows delay times between 0 and 8000 ms by individual steps of 1 ms. With the blasting equipment it is possible to blast up to 1600 detonators in one round. The paper describes the construction and functionality of this new electronic blasting system manufactured and developed by Precision Blasting Systems, a joint venture between Orica and Dynamit Nobel.
