Abstract

A control system for detonating a plurality of blast explosives is programmable to receive and store an arming sequence and firing sequence which is compared with an operator entered command. The system generates both an ARM signal and a FIRE signal, wherein the ARM signal initiates a charge circuit (26) to charge up a detonation circuit (54) and the FIRE command releases the charge to fire the circuit. The firing sequence contains a programmable delay (66) making sequential blasting possible. The system is designed to fail safely in the event both the ARM signal and the FIRE signal do not appear within a predetermined time frame.
