The present invention relates to a triggering apparatus of a nonelectric detonator using a spark ignition device and an electric blasting machine and a triggering method using thereof, which are capable of measuring a disconnection, a short-circuit, or a normality of a leading wire with a small current, checking whether a normal detonation occurs or not, and not occurring an additional detonation after a detonation. For this, the present invention is provided to compose a firing circuit by connecting both ends between two spark terminals. The triggering apparatus of a nonelectric detonator using a spark ignition device and an electric blasting machine and the triggering method using thereof comprise: a ballast resistance for checking abnormality and safety, for measuring a disconnection, a short-circuit, or a normality of the firing circuit by being applied as a resistor about a measuring current provided from a circuit checking device for checking abnormality of the firing circuit, and for protecting a spark ignition device safely by discharging a charging voltage of a capacitor after an ignition; a capacitor for compensating a voltage loss, which is capable of detonating a signal tube with a strong spark by applying a high voltage current to a spark tip due to a charging voltage by accumulating the high voltage current applied from an electric blasting machine for compensating voltage loss through the leading wire by composing the firing circuit by being connected to the ballast resistance in parallel; and a first fuse, which is disconnected by the high voltage current applied from the electric blasting machine, and which is able to measure abnormality of the firing circuit before flowing the high voltage current in the spark tip of the triggering apparatus in an ignition by being connected to the capacitor for compensating a voltage loss and the ballast resistance in parallel. |
