　　Analysis of the cause: The explosion accident was caused by the inconvenience of the operator's road XX during operation. During the process of sealing the screw, the screw was not screwed into the wooden frame of the package, but was twisted into the detonator, and the screw was in contact with the screw. In the detonator's ignition head or in the detonator in the detonator, the rotating friction causes an explosion.
