ARRANGEMENT LIMITING ACTION OF BLAST

摘要

FIELD: blasting operations, specifically, arrangement ensuring safety of blasting operations in industry and during deactivation of explosive objects. SUBSTANCE: proposed arrangement includes screen in the form of band made from multiturn spiral with clearances between turns. In this case diameter of internal turn exceeds characteristic size and band width amounts to 2-5 characteristic sizes of blasting device. Dynamic rigidity of material of band exceeds proper index of air environment. EFFECT: improved safety and efficiency of arrangement. 6 cl, 2 dwg
