Abstract
A blasting system with automated detonator logging eliminates on-the-field manual logging of each detonator. Detonators are connected in sequence in an auto-logging circuit, and the blast machine initiates a logging operation in which each detonator receives and confirms an assigned sequence number along with assigned delay data. Elimination of manual logging by individuals increases safety in the blast zone and facilitates the blasting operation. The operation is simplified, likelihood of human error is reduced, and the cost of a separate logger device is eliminated. An auto-logging protocol may be incorporated into the control module of the electronic detonator. Alternately, an auto-logging module may be connected externally to each detonator similar to the conventional surface plus down-the-hole delay systems. The inventive system may include an IDC connector that facilitates the serial connection of the detonators for the logging circuit while allowing parallel connections of the blast control circuit.
