In a system for connecting blasting caps to the initiation source, a redundant design structure provides a more reliable method of explosive initiation. This is accomplished by using a complete system from blasting control through the initiation line and connecting blocks to the blasting caps. The connecting structure between the initiation device and the blasting caps comprises explosive tubing so that both the explosive charge and the electric wires in the tube casing will initiate explosion of the blasting caps and destroy the initiation tube and wires. The connecting blocks contain additional features, such as; explosive delay times, lightning and radio frequency energy attenuation circuits.
