Abstract
"Improvements in blasting assemblies", characterized in that it essentially comprises, in combination, a metallic cup-shaped casing; a compressed explosive charge disposed at the bottom of the shell, to provide detonation; a bait charge immediately above the explosive charge; a closure element located above the bait charge and consisting of a solid deformable metal cylinder, provided with a fine core of compressed fuel composition and essentially gasless, to provide delayed initiation of the bait charge; and an explosive connecting cord length, terminating at the closure member to provide initiation thereof, and around which the top of the metal sheath is crimped vigorously; The aforementioned explosive connecting cord has a core that contains from 0.02 to 3.6 grams of explosive breaker per meter in length.
