EDD®(Electronic Delay Detonator)
EDD
®(Electronic Delay Detonator) is a high-performance electric detonator with an electric timer using lC as delay methods, enabling a highly accurate delay time and flexible time setting.
For surface blasting (A-BIOS method) / SB(Smooth Blasting)
This type of EDD
® is a sealed metal case containing an electric energy storage capacitor, IC timer, and instantaneous electric detonator dedicated to EDD
®. The standard delay time is 3 seconds in EDD
®for SB.
For multistage blasting(A-MUP method)
This type of EDD
® is a sealed plastic case containing an electric energy storage capacitor and lC timer. Electric detonator is partial ly inserted into plastic case. Delay numbers for multistage blasting consist of main and auxi l iary stages. The standard delay time of auxi l iary stage is 30 ms.
Characteristic
- Any blast delay time between 100ms and 8196ms can be set by millisecond.
- The delay time accuracy is within ±1ms of the set blast delay time.
- Combined use with the EDD® blast design software enables the high-degree controlled blasting that is unavailable from otherdetonators.
Applications
Reduction of blasting vibration and low-frequency vibration
Large scale blasting and efficient cycle time are provided by reducing blasting vibration / |ow-frequency vibration using
the principle of wave interference. Site diagnosis and blast design software are required (pay service).
Smooth blasting
High accuracy of simultaneous blasting brings a proper shape of excavation surface, enhances safety of the cavity in
the ground since the natural ground is not damaged, and increases the efficiency of cycle time. Accordingly, EDD
® is
suited to the smooth blasting method for excavating tunnels with a large cross section and large cavities in the ground.
