In order to determine the thresholds and detonated path of the strip-shaped transfer charge used in the flatbed explosive train, an explosive train sample using JO-9C(III) strip-shaped transfer charge was designed to study the minimum thickness of thestrip-shaped transfer charge and the minimum safe distance between transfer charge and the electric detonator. The transfer experiments were conducted using explosive train of different thick strip-shaped transfer charge in which the electric detonators were in an armed position. The detonation interruption experiments were followed conducted using explosive train with different safe distances. The shock wave attenuation rule is applied to verify the experimental results and determine the detonated path. The calculated and experimental results were in very good agreement. The results show that the minimum thickness ranged from 0.2mm to 0.4mm. the minimum safe separation distance ranged from 0.4mm to 0.6mm; and the strip-shaped transfer charge is detonated by a shock wave from rather than air clearance when the safe distance is less than the minimum threshold.
