<p>The invention involves detonators with improved settings of spatial and initial power and brisance effects, where the detonator contains delayed-action pyrotechnic, primary and secondary charges arranged in a line and characterised by the principle that both primary (4) and secondary (3) explosive sub-charges are placed in the detonator jacket (1) in the first internal casing (2), which is shaped, at least along its part containing the secondary explosive charge (3), a prismatic shape.</p> |
