Abstract: The present invention relates to an electric detonator (1) comprising a cap (2), comprising a priming charge (3) and an electrode (4), comprising a positive pole, a negative pole and a resistor element (8), the said priming charge (3) comprising at least two primary explosives, a first primary explosive (9) and a second primary explosive (10), and at least one secondary explosive (11). The electric detonator is characterized in that the two primary explosives (9, 10) and the secondary explosive (11) are arranged in layers, in an increasing degree of sensitivity, bearing one against the other, wherein the first primary explosive (9), constituting the most sensitive of the two primary explosives (9, 10), is arranged closest to the resistor element (8), and in that the second primary explosive (10) is arranged thereafter between the first primary explosive (10) and the secondary explosive (11). The invention also relates to a production method for the said electric detonator (1).

Abstract: An initiating device including at least one detonator, at least one booster charge and an action charge. The at least one booster charge is arranged such that, at the action charge initiates, the booster charge is free from disturbing edge effects that can have a disturbing effect on the action charge. A booster casing in which the booster charge is disposed is configured with a rear cylindrical part having a diameter D1, a front conical part delimited by a first circular limit face having the diameter D1, and a second circular limit face having a diameter D2, wherein the two limit faces are plane-parallel at a distance H1 from each other, wherein H1/D2 lies within a range 0.5-1.5. Also, a production method for producing the booster charge.
