Abstract
With the aim to overcome the impractical problems with the prior art, the utility model discloses a time-delay electric spark device and time-delay electric detonators with the same which comprise a firing element, a casing, and time-delay powder contained inside the casing. The firing element consists of a foot line, an electrically firing line as well as electric resistance wire arranged between the foot line and the upper end of the electrically firing line and connected to the upper end. The electric resistance wire and the foot line as well as the upper end of the electrically firing line are all disposed in the casing above the time-delay powder and the other ends of the foot line and the electrically firing line both extend out of the casing and are further connected with the positive and the negative electrodes of a power source. By the introduction of time-delay detonators driven by different time-delay electric spark devices, the time-delay detonators are buried around the to-be-blast zone successively according to different delayed time; and at the same time, the foot line and the electrically firing line are both kept communicated with the power source through a control switch. Since the delayed time differs greatly, the detonators blast in the order of the pre-determined delayed time, therefore, preventing the occurrence of coincidental blasting.
