FIELD: transport.
SUBSTANCE: invention relates to icebreaker navigation and concerns technique of ice breaking operations and clearing water bodies of ice cover. Method of canal laying in ice covers consists in that an explosive agent from vessel board is delivered via canal route to ice field ahead of the vessel at safe distance, and then the next area of ice field is disrupted by explosion. As explosive agent, combustible materials crushed to suspending in air are used. These materials are dispersed over ice field area to be disrupted in close to stoichiometric ratio with air and using proximity fuses.
EFFECT: invention permits to reduce execution period of ice-breaking operations, cost of their execution and increase productivity of ice breaking.
