FIELD: devices affording protection against snowslides, avalanches or falling rocks, particularly to stimulate avalanching at predetermined time.
SUBSTANCE: method involves installing vessel on slope in avalanche hazardous areas before snowfall period; fastening thereof to slope; connecting the vessel with hose and conductor cable; locating hose and cable ends in safe locality. If avalanche hazard occurs the vessel is filled with gaseous explosive mixture via hose laid under snow blanket and the explosive mixture is blasted.
EFFECT: increased reliability, safety and efficiency, reduced costs, increased technological effectiveness and time of avalanching initiation.
