TECHNICAL DATA SHEET
Technical Properties
Description
Lubaex™ Edderkop™ boosters have been specially designed for use in underground upholes. They consist of a plastic shell filled with a high explosive composition. Two longitudinal tunnels in the boosters are offset to avoid abrasion damage to signal tube or leadwires by the loading hose. At the base of the booster the tunnels are joined by a smooth, curved channel, which protects the detonator signal tube or lead wire from kinking and from sharp and rugged objects.
Additional to the booster is a slip-on spider, which allows the Lubaex™ Edderkop™ booster to be easily pushed into the hole but retains its intended central position in the blasthole. Lubaex™ Edderkop™ boosters can securely hold the detonator in place during loading, while still enabling safe removal of the detonator if required.
Safety
Lubaex™ Edderkop™ boosters contain molecular explosives, which can be initiated by intense impact, friction or heat. As with all high explosives, Lubaex™ Edderkop™ boosters should be handled and stored with care.
Boosters must be handled with care and avoid impact with a solid surface or another booster. Any such collision may cause damage that could lead to a misfire, or a premature initiation. Lubaex™ Edderkop™ boosters may be used at temperatures up to 70ºC. DO NOT use these boosters with any detonator, which cannot be completely contained within the booster. If this is not observed, damage to the detonator may occur during charging which may lead to a premature detonation.
Lubaex™ Edderkop™ boosters are supplied in Class 1.1D packaging and have UN Number 0042.
Application
Lubaex™ Edderkop™ boosters are reliably initiated by detonators or by detonating cords containing at least 10 g/m PETN. Lubaex™ Edderkop™ boosters are designed to initiate commercial explosives in hole diameters up to 165 mm. Lubaex™ Edderkop™ boosters will function reliably in any depth of water encountered in the mining environment.
Recommendations For Use
Push the detonator through the side tunnel, and then back through the hole in the center tunnel. Place the loading hose into the recess and push the Lubaex™ Edderkop™ complete with detonator gently up to the hole to the desired location.
Withdraw the loading hose approximately 150 mm and begin explosive loading, making sure the detonator signal tube is not coiled or twisted in the hole.
Excessive force should not be applied to signal tubes connected to in-hole detonators and boosters. If a booster becomes stuck when attempting to retrieve or reposition it, a replacement unit should be used.
Packaging
Lubaex™ Edderkop™ boosters are packed in cardboard cases. The case dimensions are 0.356 m x 0.261 m x 0.135 m. A case weighs 9 kg and contains 30 boosters.
Lubaex™ Edderkop™ Spiders are purchased separately.
