초록

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 sens...
