摘要：
This paper describes the results of experiments on laser initiation of composites based on PETN and inclusions of submicron coal particles. The thresholds and kinetic characteristics of explosion of mixed compositions based on PETN and inclusions of submicron coal particles (brown coal B and parabituminous coal P) are studied under the impact of neodymium laser (1064 nm; 12 ns), depending on the mass concentration of inclusions in the range of 0–5%. It is shown that the minimum threshold of explosive decomposition of PETN equal to 1.1 J/cm2 can be achieved if the concentration of both types of inclusions is 0.5%.
