INFLUENCE OF TAMPING ON PERFORMANCE OF LINEAR SHAPED CHARGES

摘要

Nowadays we are often confronted with limitation of quantity of explosives in terms of protection of surroundings, hygienic standards etc. Linear shaped charges (LSC) as such represent significant reduction in quantity of explosives (when compared with open charges) at blasting work, especially at demolitions of metal structures. Further decrease in quantity of explosives is achieved by tamping. This report deals with finding of relationship (represented by cavity depth produced by jet of LSC in steel plate with 30 mm thickness) between tamped and open LSC of the same performance.
