Study on a Micro-miniature Staggered Explosive Train

A micro-miniature explosive train of loaded strip-shaped detonating explosive was designed for propagation in the micro-channel. Pressing methods of strip-shaped charge were improved. The micro-miniature electric detonator and booster at both terminals of strip-shaped detonating explosive were used as input and output of explosive train, and the propagation channel with two right angles was formed. According to detonating test by displacing the detonator in-line and explosive-proof test by displacing the detonator out-line, the technology of improved charging ways are all right, 0.8 mm strip-shaped detonating explosive can detonate reliably, 2 mm explosive-proof safety can be achieved by the shortest distance from electric detonator to detonating explosive.
