Insensitive and high-powered explosive material development to manufacture cumulative charge cutters

The article presents the theoretical and applied research aimed at development and investigation of an insensitive and high-powered explosive for safe commercial and special blasting operations, and at design of cumulative charge cutters using this explosive material. Explosive polymers operate differently in different conditions. Explosive polymers are insensitive to external mechanical impact and inflammable in heating, but pressure increases in the sample and the sample fractures when polymers decompose. Depending on the content of an explosive, it is found that the explosive and polymer composition can provide explosive characteristics of trinitrotoluene while keeping insensitive relative to standard detonators. A cumulative charge cutter can be used for the industrial and special purposes. It has a plastic carrier, is readily cuttable, and can be quickly and conveniently glued on any uneven surface, which makes it extremely suitable in application. The developed insensitive explosive polymer has a high detonation velocity, over 7400 m/s, and can be used to manufacture charges of various shape subject to the task assignment.

Keywords: explosive, insensitive explosive, blasting, explosive polymer, cumulative charge cutter, trinitrotoluene, gaseous products, blasting technologies, drilling.
