Description

TIGER CORD detonating cords are flexible linear explosives with a core of PETN explosive encased in a textile outer jacket. TIGER CORD detonating cords are designed for use as trunklines and/or downlines in various mining, quarrying and construction applications.

 

TIGER CORD is available with a variety of PETN charge weights 5 g/m to 80 g/m designed for different applications.

APPLICATION RECOMMENDATIONS

  • ALWAYS cut detonating cord with a sharp, non-sparking knife.

  • ALWAYS use square knots to extend/join detonating cords that will propagate self- to-self. When connecting downlines to trunklines, always use a clove hitch knot and keep incoming and outgoing cords at right angles to avoid possibility of cut-offs.

  • ALWAYS use a detonating cord product, such as TIGER CORD detonating cord with a greater explosive core load as a trunkline to initiate TIGER CORD.

  • TIGER CORD is a high explosive that must be handled with care and respect at all times.

  • Except for a direct lightning strike, TIGER CORD detonating cord is unaffected by stray currents generated by electrical storms, power lines and radio/radar transmitters which make electric firing comparatively hazardous.

  • Intense impact or friction can initiate TIGER CORD but is insensitive to initiation during normal handling.

  • TIGER CORD can detonate if subjected to extremely high temperature, but remains stable and safe to use below 70°C. For temperatures between 70°C and 80°C exposure time should not exceed 24 hours.

  • ALWAYS use a double wrap clove hitch knot to connect TIGER CORD detonating cord to the trunkline cord.

  • Never allow trunklines and/or downlines to cross.

  • Minimum recommended initiating detonator is a No. 6 or 8 strength or nonelectric detonator. The detonator must be taped 20-30 cm from the cut-off end and the bottom of the detonator must point in the cord’s direction of detonation.

  • Intense impact or friction can initiate TIGER CORD but is insensitive to initiation during normal handling.

  • When using detonating cord under water, cord ends must be sealed with tape.

  • When splicing two cords they must be tied together with secure knot or taped together with a length of at least 10 cm.

  • Trunk lines must be laid in such a way that the detonation from the primary cord continues in the same direction when it transfers over to the trunk line core.

  • Connected cords and trunk lines cords of detonating

  • cords should be affixed outside boreholes.

  • To prevent transmission between multiple parallel running cords, the distance between cords should be at least 1 metre.

  • Additionally, JEPL also recommends the following to be considered:

  • To prevent spillage of pentrite and moisture to penetrate into the yarn encasement, the cord ends should be sealed with tape immediately after cutting.

  • Dry pentrite is very sensitive to impacts.

  • Wet pentrite has low sensitivity; interruption in detonation may occur.

  • Avoid knots and loops on the cord during charging. This may cause interruption in detonation.

  • In case of spillage or if remainders of detonating cord are found after blasting, these must be collected and treated as explosives
