ONDE EXPLOSIVE [2 records]

Record 1 2005-01-28

English

Subject field(s)
  • Blasting Work (Mining)
  • Physics
CONT

Explosion wave. From the French, onde explosive, and coined by Bertholet, signifying that wave or flame which passes through a uniform gaseous mixture with a permanent maximum velocity. The rate of the explosion wave is a definite physical constant for each mixture. The explosion wave travels with the velocity of sound in the burning gas which itself is moving rapidly forward en masse in the same direction, so that the explosion wave is propagated far more rapidly than sound travels in the unburned gas.

French

Domaine(s)
  • Travail aux explosifs (Exploitation minière)
  • Physique
CONT

La sensibilité à l'onde explosive est fonction de la densité de l'explosif et de son état (pulvérulent, gélatineux, fondu). Quand la densité est trop élevée, surtout avec les explosifs nitratés, l'onde explosive provoquée par le détonateur peut ne pas agir, ou s'arrêter en cours de propagation : on a alors un raté, ou un culot d'explosif.
