Title (EN) PROCESS AND DEVICE OF CONTROLLED TRIGGERING OF AVALANCHES
(FR) PROCEDE ET DISPOSITIF DE DECLENCHEMENT CONTROLE D"AVALANCHES
Abstract: front page image
(EN)An explosive charge is brought from a starting point (B) safe from avalanches to the breaking region (A) of an avalanche by means of a remote controlled transport vehicle, for example a helicopter in the form of a scale model. The explosive charge and a sensitive element at a minimum distance of the snow surface are assembled together into an explosive block so that the explosive charge may be positionned at a predetermined height above the snow surface. Then the charge is exploded from the start point (B) preferably by means of a captive cable.
(FR)On amene une charge explosive a partir d"un point de depart (B) a l"abri des avalanches vers la region de rupture (A) d"une avalanche au moyen d"un vehicule de transport teleguide, par exemple un helicoptere sous forme de modele reduit. La charge explosive et un element sensible a une distance minimum de la surface de la neige sont reunis dans un bloc explositif de facon que la charge explosive puisse etre positionnee a une hauteur determinee au-dessus de la surface de la neige. Ensuite, on fait exploser la charge a partir du point de depart (B), de preference au moyen d"un cable captif.
