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.
