Velocity of Detonation, Product Timing

Application of Velocity of Detonation Measurements of explosive products includes:

  • Test the performance of explosives against the quality control standards set by the manufacturers
  • Measure the continuous VOD in any charge diameter under confined or unconfined conditions
  • Determine the critical diameter and critical density of an explosive charge,- Determine the gap sensitivity of explosives
  • Measure the timing accuracy of detonators
  • Measure the continuous VOD of primers/boosters
  • Determine the minimum booster size for any explosive by measuring run-up velocities
  • Measure the continuous VOD in any hole diameter, wet or dry holes, and in any type of rock or multiple holes per blast,
  • Determine whether full detonation, low order detonation or failure occurred, and where in the explosive column it happened,
  • Check VOD’s against manufacturers' specifications in full scale blasting environments
  • Determine the minimum booster size for any explosive by measuring run-up velocities in full scale blasting environments
  • Measure the timing accuracy of detonators in full scale blasting environments
  • Measure the effects of water, drill cuttings, and rocks, etc. trapped within the explosive mass
  • Determine the length of explosive column to use in decking operations to evaluate the effect of stemming and drill cutting dilution, water pick-up, etc. on the explosive run-up requirements 
  • Determine the correct length and type of stemming material to be used between decks of explosives to prevent sympathetic detonation or explosive desensitization from occurring
  • Measurement of Explosive Product Timing.
