Abstract
The invention concerns a device for provoking the collapse of a snow cornice comprising several exploders (11). Each exploder (11) consists of a main cylinder (12), perpendicular to the support base (14) arranged flat on the ground, and a positioning tube (13) connected to the main cylinder and mounted on a rigid seat (15) fixed to the mountain side. A supply conduit (20), connected by conduits (23, 24) respectively to an oxygen cylinder and a propane cylinder stored in a shelter (22), supplies via conduit sections (9) a detonating gas mixture, obtained from two gases, into the positioning tube (13) and into the main cylinder (12). Igniting means (21) mounted upstream of the supply conduit (20) ensure the ignition of the detonating gas mixture.

A device for provoking collapse of a snow cornice, the device comprising:
- at least one gas exploder (11) comprising:
- a support base (14) having a bottom surface for resting against a ground surface and a top surface supporting a main cylinder (12) extending substantially perpendicular to the support base (14);
- a rigid seating (15) for attachment to a side of a mountain and a hollow positioning tube (13) having a first end mounted to the rigid seating (15) and a second opposed end connected to the main cylinder (12);
- a supply conduit (20) communicating with the positioning tube (13) for supplying a mixture of an explosive gas to the main cylinder (12) via the positioning tube (13), an upstream end of the supply conduit (20) being connected to a first flexible conduit (23) for connection to a source of oxygen and to a second flexible conduit (24) for connection to a source a combustible gas;
- and
- an ignition system (21) attached to the supply conduit, adjacent the upstream end of the supply conduit, for igniting the explosive gas mixture when desired;
- wherein the first end of the positioning tube (13) is articulated to the rigid seating (15) about a generally horizontal axis.
A device for provoking collapse of a snow cornice, the device comprising:
- a plurality of gas exploders (11), each of the plurality of gas exploders (11) comprising:
- a support base (14) having a bottom surface for resting against a ground surface and a top surface supporting a main cylinder (12) extending substantially perpendicular to the support base (14);
- a rigid seating (15) for attachment to a side of a mountain and a hollow positioning tube (13) having a first end mounted to the rigid seating (15) and a second opposed end connected to the main cylinder (12);
- a supply conduit (20) communicating with the positioning tube (13) of each of the plurality of gas exploders (11) for supplying a mixture of an explosive gas to the main cylinders (12) of the plurality of gas exploders (11) via the positioning tubes (13), an upstream end of the supply conduit (20) being connected to a first flexible conduit (23) for connection to a source of oxygen and to a second flexible conduit (24) for connection to a source a combustible gas;
- and
- an ignition system (21) attached to the supply conduit, adjacent the upstream end of the supply conduit, for igniting the explosive gas mixture when desired;
- wherein the first end of the positioning tube (13) is articulated to the rigid seating (15) about a generally horizontal axis;
- and
- the supply conduit (20) has a down stream portion comprising a conduit branch element (9) connected with each of the plurality of gas exploders (11), the conduit branch element is arranged such that a distance between the ignition system (21) and the plurality of gas exploders (11) is the same for each one of the plurality of gas exploders (11) in order to provoke simultaneous explosions in each of the plurality of gas exploders (11).
