An explosive device (10) comprising: an explosive charge body (12) including an explosive charge and detonator (21); a housing (22) attached to the explosive charge body (12); and a length of electrical or non-electrical non- pyrotechnic firing line (26) having a first (28) and second end (32) the majority of which is stored within the housing so as to permit progressive removal from the housing on pulling the first end (28) thereof, and which is attached at the second end (32) to the detonator (21). The explosive device (10) can be used in a versatile manner for avalanche control, can allow a degree of positioning after initial deployment and provide safe operation yet is easily handleable, readily deployed and compact, and negates the hazards associated with the use of pyrotechnic delay fuze.

La présente invention concerne un dispositif explosif (10) comprenant: un corps de charge explosive (12) contenant une charge explosive et un détonateur (21); un logement (22) fixé au corps de charge explosive (12); et un segment de ligne de tir (26) non-pyrotechnique électrique ou non électrique présentant une première (28) et une seconde (32) extrémité dont la majeur partie est logée dans le logement pour permettre son retrait progressif du logement en tirant sur la première extrémité (28), ce segment étant fixé par la seconde extrémité (32) au détonateur (21). Le dispositif explosif (10) peut être utilisé de différentes façons pour le contrôle d'avalanche, peut permettre un degré de positionnement après le déploiement initial et une manipulation sûre et facile, en plus d'être compact et de déploiement rapide, et enfin, écarte les dangers associés à l'utilisation de fusée à retard pyrotechnique.
