Abstract
The improved low-energy detonating fuse is lightweight, flexible, strong and non-conducting. It detonates at a high rate and is adapted to modern rapid production methods. It has a continuous core (2) made of deformable, bound explosive containing a crystalline high-explosive compound, preferably fine-particulate pentaerythritol tetranitrate mixed with a binder. The crystalline, high-explosive compound is present in an amount of approximately 0.1 to 2 g/m. The core is surrounded by a plastic protective sleeve (4) which is approximately 0.13 to 3.18 mm thick. Preferably the binder-containing explosive core is reinforced at its circumference between the core and the plastic sheath by at least one yarn strand (3) in particular the fuse contains a core reinforcement consisting of at least one endless yarn strand at the circumference of the core and extending virtually parallel to the longitudinal axis of the core, the reinforcement having a tensile strength such that the core is prevented from contracting to the yield point under the effect of the forces normally occurring during charging of a borehole.
