  • Method for installing a set of electronic detonators and associated ignition method
    Patent number: 12392593
    Abstract: A method for installing a set of electronic detonators in blast holes of a mining face includes the following steps: connecting detonators, charged into the blast holes, to a movable test device; receiving, by the movable test device, a message sent by each detonator; determining, from that message, a set of values, representing the total number of detonators connected to the movable test device; sending, to one or more detonators of the set, a data set to store including the set of values representing the total number of detonators connected to the movable test device; and storing the data set in the memory of one or more detonators of the set of electronic detonators. Use for later verification of the connection of the detonators before firing.
