PROJECTIVE EXPLOSIVE SUBSTANCE, METHOD AND APPARATUS FOR PREPARATION THEREOF Russian patent published in 2006 - IPC C06B21/00 

FIELD: explosives.

SUBSTANCE: invention, in particular, relates to perforated projective substance. Invention consists in that, after imparting needed geometric shape to projective substance, the latter is subjected to perforation operation fulfilled by a certain number of perforation number, which form a large number or through or blind holes parallel to each other and uniformly distributed throughout the bulk of projective substance, wherein those holes are made at a distance between them equal to doubled value of needed burning length in charge, for which projective substance is intended. In particular, perforation is fulfilled with pin punch (5) containing multiple pins (6), which are inserted into projective substance to needed depth and then returned to initial position.

EFFECT: enabled preparation of high-density projective substance.
