Abstract

An electronic blasting system comprises multiple detonators connected or connectable to at least one blasting box. A plurality of logging devices are used for interrogating and programming the detonators. One of the logging devices is initialized as a key logger. The key logger is the only device in or associated with the electronic blasting system that is capable of initializing each blasting box as a control unit or as a blaster unit or as a combination control unit and blaster unit, and/or of authorising arming and firing of a blast in the electronic blasting system. A method of facilitating secure arming and firing in an electronic blasting system, using the key logger, is disclosed.
