Detonating cordDetonating cord provides strong and reliable initiation of explosive charge and detonation is almost immediately transferred to all explosive charges. It consists of continual explosive charge with PETN. PVC coating makes it water-resistant. Detonating cord is successfully applied in mass blasting in open pits and quarries and in demolishing underwater structures and structures on the surface. It cannot be used in mines where methane and explosive coal dust are present. Detonating cord has strong elongation, flexibility and it is easily tied in knots.
Safety fuseUniversal safety fuse is used for ignition and together with the blasting cap it initiates cap-sensitive explosives, on the surface or underground. That is possible if methane and explosive coal dust are not present. The core of the universal safety fuse is made as continual charge of fine-grained black powder. It is surrounded by cotton yarn and layer of black-coloured plastic isolation. It is used in dry and damp conditions and also for working underwater at the depth of up to 10 meters. The burning time of the cord is significantly shortened when it burns under pressure (under water or in loaded borehole).
