CUTTING SEA ICE BY DIRECTED BLASTING

The use of directed blasting can prove a very effective means in solving a number of practical problems: the creation in the pripay (fast shore ice) of ice-free channels for the passage of ships with a weak hull, for laying pipes or cable from the ice surface, and so forth. Placing the charges according to a prescribed system and exploding them through brief time intervals in a fixed sequence can assure the directed removal of ice along the given direction. (Author)
