Abstract: A ground-fixable electronic detonation device for a blasting system and a blasting system using same are proposed. The ground-fixable electronic detonation device includes: an electronic detonator; a wireless communication module; a wire part configured to connect the electronic detonator and the wireless communication module; and a module fixing pin part positioned in the wireless communication module and configured to move upward and downward to be driven into the ground. In the ground-fixable electronic detonation device, the module fixing pin part is driven into the ground to stably fix a position of the wireless communication module, so that stability in wireless communication is secured. Accordingly, blasting accuracy may be improved.

Abstract: A detonator includes a control circuit and a charging circuit. The control circuit receives a first signal transmitted using a voltage applied to a cable by a blasting device and transmits a second signal to the blasting device using a current flowing to the cable. The charging circuit performs a charging operation by receiving the voltage through the cable. The charging circuit stops the charging operation while the control circuit transmits the second signal to the blasting device.

Abstract: The present disclosure relates to a blasting system. The blasting system includes: detonators disposed in blasting holes perforated in a blasting target, and provided to detonate explosives; and a worker terminal configured to be connected to any one of the detonators by a worker. Wherein the worker terminal includes: a storage part configured to store a blasting map; a terminal position generation part configured to generate a terminal position indicating a position of the worker terminal; and a determination part configured to receive the logging signal, and match the terminal position at the time when the worker terminal receives the logging signal with the blasting map to identify a detonator connected to the worker terminal.

Abstract: The present disclosure relates to a connector for a blast-triggering device, said connector including a connector head in which a rear end thereof is integrally connected with a rear surface of a connector body, an upper surface thereof is formed in a curved surface extending from the rear end thereof to a front end thereof, a tube insertion portion is provided between a lower surface thereof and the connector body so that a plurality of shock tubes is fitted therein, and the front end thereof is separated from the connector body. Thus, it is possible to maintain the shape of the connector during detonation, thereby minimizing the generation of debris and improving the safety at the time of detonation. In addition, it is possible to prevent damage to the plurality of shock tubes, thereby preventing a cut-off phenomenon caused by damaged shock tubes during detonation.

Abstract: Proposed is an emulsion explosive composition containing 80% to 95% by weight of an oxidizing agent aqueous solution containing hydrogen peroxide, nitrate, and diethylene triamine penta(methylene phosphonic acid) (DTPMPA), 0.1% to 10% by weight of an emulsifier, and 2% to 15% by weight of an oil. The emulsion explosive composition can effectively solve self-gassing problems caused by a reaction between hydrogen peroxide and nitrate.
