PROCESS AND DEVICE FOR TRIGGERING AN AVALANCHE

摘要

The above device consists mainly of a rigid explosion tank (10) with a closed rear end (11) and a front opening (12). Said tank is mounted in the direction of the slope on which the avalanche is to be triggered. It is connected to a fuel gas supply station (19) and to an oxygen-carrying gas supply station (20). These two stations are linked by pipes (17 and 18) to injection nozzles (16) situated inside the tank (10). An ignition device (29) is mounted in the bottom of the tank and can be operated by remote control by means of a triggering device (30). An advantage of the above device is that the explosion is exponentially propagated inside the rigid explosion tank and causes a powerful high-velocity blast to be expelled from the latter.
