FIELD: blasting.
SUBSTANCE: method includes installation of explosive charges under ice and their by-turn blasting with a time interval equal to the time of flexure-gravity wave travelling from an area of blasting of the previous charge to an area of blasting of the next charge. Explosive charges are installed above an ice cover and blasted simultaneously with blasting of charges installed under the ice cover. Prior to installation of explosive charges wind speed and direction, underwater currents and ice field drifts are measured, ice thickness is identified. Explosive charges are installed to generate a direction of impact wave propagation to opposite sides from an area of location of a marine facility of business operations.
EFFECT: higher reliability of protection of a marine facility of business operations against exposure of ice formations.
