Abstract: A method and apparatus for controlling a blasting operation using blast control equipment to initiate a plurality of detonators at a blast site. According to the method, the full use of the blast control equipment is inhibited, a validation process on information is conducted, and, if the information is validated, at least partial use of the blast control equipment is enabled. The blasting system includes at least one installation of blast control equipment and a plurality of detonators that are configured to be initiated by the blast control equipment, a control facility, and a transmitter for transmitting an enabling signal to at least one selected installation which allows the blast control equipment at the selected installation to initiate the plurality of detonators.

Abstract: A blasting system which includes a control unit, a communications bus which is connected to the control unit, a plurality of detonators which are connected in sequence to the communications bus along its length, and a daisy chain connection between the control unit and the detonators, and wherein, within the sequence of detonators, a first detonator makes use of the daisy chain connection to enable a second following detonator so that data can be exchanged between the control unit and the second detonator using the communications bus.

Abstract: A detonator which, once armed, is automatically disarmed after a predetermined time period in the absence of at least one defined signal during such time period.
