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%.
