Abstract: The present disclosure relates to a trunkline delay detonator and a blast-triggering device using the same. In the blast-triggering device, a trunkline delay detonator is inserted into a connector in such a manner that a plurality of shock tubes connected to a detonator for initiating an explosive are interposed between the connector and the trunkline delay detonator, so that an explosion signal is applied to the shock tubes by detonation of the trunkline delay detonator.
