Abstract
The invention discloses a novel low-strength basic detonator and a preparation method thereof. In order to satisfy the demand on the surface delay detonator at home and abroad, the invention research one of the difficulties of the surface delay detonator: the basic detonator. The novel low-strength basic detonator comprises a flat bottom tube, a first charge, a second charge and a reinforcing cap. According to the low-strength basic detonator, under the premise that reliable excitation of a booster tube is satisfied, the strength of the detonator is effectively reduced to avoid the bottom metal jet, so that the detonating network is effectively protected, the network is prevented from being damaged by the surface delay detonator, and the detonating reliability is improved, thereby precisely detonating hole by hole. According to the invention, the aluminum alloy flat bottom tube is adopted, and an energy-gathering hole of a common tube is eliminated, thereby not only simplifying the production process, but also effectively avoiding the metal jet at the bottom of the detonator. Meanwhile, matched with the first and second charges, the brisance of the novel low-strength basic detonator disclosed by the invention is far below that of a #8 detonator, thereby effectively avoiding damage to the peripheral booster network.
