For the explosive network, in addition to the network explosive and the filling process itself having sufficient reliability, the network structure design also plays a crucial role in the reliability. Under the condition of the same network explosive formula and the same filling process, the transmission performance of the network on different network structures will have a large difference. Especially the groove design related to the network transmission.

[0003] The design of the explosive network groove is to extend the wiring as much as possible in the limited space size to meet the sufficient delay, so that the groove design is bent through multiple corners. The detonation propagation, corner, and detonation shock of adjacent grooves of the straight-line groove will affect the groove transmission. From the design point of view, the factors affecting the transmission reliability of the network explosive in the small-size groove channel network mainly include the rigid substrate material, the groove cross-sectional size, the groove corner, the distance between adjacent parallel grooves, and the explosion isolation. The present application is aimed at the design of the millimeter-level small-size groove structure, based on the law research and understanding of the influencing factors, and determines the structure design more conducive to the improvement of the transmission reliability of the network explosive, so as to improve the weapon reliability. The cost is low, the effect is remarkable, the application range is wide, and it is suitable for all network designs involving small-size grooves of the explosive network, whether it is an explosive synchronization network or a logic network. Through the network structure design, the structure size can be reduced as much as possible under the premise of meeting the reliability requirements, so as to realize the miniaturization of the explosive network.
