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. In the blasting detonator, close contact between the outer surface of the trunkline delay detonator and the shock tubes is improved, whereby energy lost in an explosion is reduced and an explosion signal is stably and uniformly applied to the shock tubes by using powder which has a weak explosive power and is relatively insensitive compared to conventional powders.
