A simplified blasting system enables utilization of electronic delay detonators (23e) and pyrotechnic delay detonators (23p) in a simplified blasting set up. Both the electronic time delay detonators (23e) and the pyrotechnic delay detonators (23p) have shock tube fuses (32) which enables both types of detonators to be initiated by a common trunkline such as a low energy detonating cord trunkline (38). This system eliminates the need for separate firing systems, an electric firing system for electrically-initiated electronic delay detonators and a detonating cord trunkline for the non-electrically-initiated pyrotechnic delay detonators.
