A method for installing a set of electronic detonators into blast holes of a workface comprises the following steps: - connection (S41) of the detonators, loaded into the blast holes, to a mobile test device; - receipt (S42), by the mobile test device, of a message sent by each detonator; - determination (S43), using this message, of a set of values {V} representative of the total number of detonators connected to the mobile test device; - sending (S44), to one or more detonators of the set, a set of data {D} to be stored comprising the set of values {V} representative of the total number of detonators connected to the mobile test device; and - storage (S45) of the set of data {D} in recording means of one or more detonators of the set of electronic detonators. Use for later verifying the connection of the detonators before ignition.
