Abstract

1,243,647. Blasting. MEDIATOR AB. OY. 8 Aug., 1968, No. 37870/68. Heading E1F. [Also in Division F3] A method of destroying submerged boulders comprises placing a plurality of hollow charges around the boulder (Figs. 6b, 7 and 8 not shown) and detonating the charges, the explosive material in the charges having a detonation velocity not exceeding 5000 metres/ second, e.g., dynamite and ammonium nitrate explosives.
