Abstract
An electronic delay detonator logging control device and a method therefor are disclosed. The state and the connection of a plurality of electronic delay detonators connected in parallel and a trunk line are inspected before blasting so as to check for an incomplete connection and prevent a partial misfire. A log counter is assigned to the plurality of electronic delay detonators such that the plurality of electronic delay detonators can be blasted in desired blasting patterns or in sequence. In the event of a failure, a logging recovery mode is operated so as to recover connection information of the plurality of electronic delay detonators.
