Title (EN) BLASTING METHOD AND BLASTING BAG
(FR) PROCEDE ET POCHE D'EXPLOSION
Abstract:
(EN) A blasting method which comprises forming a hole in an object to be blasted, inserting an explosive into the hole, filling the hole with a fluid and igniting the explosive in this state. Since the fluid propagates efficiently the blasting force of the explosive, the blasting force covers the whole area of the hole filled with the liquid so that blasting can be accomplished uniformly with a high blasting force. A blasting bag is made of a flexible material and is provided with an inlet for introducing the fluid into the bag. The hole can be filled with the liquid easily and reliably by using this blasting bag.
(FR) Procédé d'explosion consistant à former un trou dans un objet que l'on doit faire exploser, à insérer un explosif dans ce trou, à remplir ce trou d'un fluide et à allumer l'explosif dans cet état. Le fluide propageant efficacement la force d'explosion de l'explosif, la force d'explosion couvre la totalité de la surface du trou rempli du liquide de sorte que l'explosion peut s'effectuer uniformément avec une force élevée. Une poche d'explosion est réalisée en un matériau souple et est pourvue d'un orifice d'admission pour y introduire le fluide. L'emploi de cette poche d'explosion permet de remplir le trou de liquide aisément et de manière fiable.
