<p>The invention identifies a serious defect in the detonation of solid explosives against target surfaces, particularly against convex surfaces and proposes a new method for detonating a solid explosive to increase the efficiency thereof. In one embodiment, for cutting a tube (63) circumferentially, the explosive mass (61) is applied to the target surface (63a) and a layer of a second explosive material (62) is applied to that surface of the mass of explosive most remote from the target (63). The second explosive material (62) has a detonation speed faster than that of the mass (61) and is detonated first to transmit detonation front into the mass (61) whereupon the detonation front in the mass (61) is always forwardly inclined.</p> |
