FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to explosive compositions for initiation devices with different types of engagement for use in mining and coal mining industry, in oil production at well perforation, in construction and special equipment. Initiation composition contains 99.8–96 wt. % of condensed explosive, in particular initiating explosive (IE), high explosive, explosive type explosive in a series of coordination compounds, up to 2 wt. % optical polymer and 0.2–2 wt. %, sensitizing additive - carbon fulleroid nanomodificator - astralene A, B or C. To obtain a nanomodified composition - astralene A, B or C in form of its suspension in a polar solvent is mixed with a solution of condensed explosive followed by precipitation of particles of astralene on particles of condensed explosive, and then introducing an optical polymer.
EFFECT: technical result consists in increase of sensitivity of initiating compound to laser radiation and impact-wave action, and also in increase of charge density.
