Qu'est-ce que la VOD ?<\/strong><\/h6>\n\t<\/div>\n<\/div>\n\n\n\n

La vitesse de d\u00e9tonation (VOD) est la vitesse \u00e0 laquelle l'onde de choc se propage \u00e0 travers un explosif en d\u00e9tonation. La \nVOD est cit\u00e9e par les fabricants d'explosifs pour un explosif donn\u00e9 dans des conditions donn\u00e9es. La VOD d'un explosif \nd\u00e9pend des caract\u00e9ristiques de l'explosif, telles que la formulation, la densit\u00e9, la taille des particules, le diam\u00e8tre et le \ndegr\u00e9 de confinement. Elle d\u00e9pend \u00e9galement des facteurs affectant ces caract\u00e9ristiques, tels que l'infiltration d'eau ou \nd'autres impuret\u00e9s, la pression statique et la pression dynamique.<\/p><\/div>\n

\n\t
\n\t\t
Pourquoi la VOD est-elle importante ?<\/strong><\/h6>\n\t<\/div>\n<\/div>\n\n\n\n

La VOD influence la mani\u00e8re dont l'\u00e9nergie est lib\u00e9r\u00e9e par l'explosif sous forme d'\u00e9nergie de choc et d'\u00e9nergie de \nsoul\u00e8vement. Cela affecte la fragmentation et le lancement du rocher explos\u00e9 ainsi que le co\u00fbt de l'extraction des \nmin\u00e9raux pour la mine.<\/p><\/div>\n

Comment la VOD est-elle mesur\u00e9e ?<\/strong><\/h6>\n\t<\/div>\n<\/div>\n\n\n\n

MREL fournit les moyens d'enregistrer facilement la VOD r\u00e9elle atteinte par l'explosif tout au long de la longueur de la \ncolonne d'explosif.<\/p><\/div>\n\t\t<\/div> \n\t<\/div>\n\t<\/div> \n<\/div><\/div>\n\t\t\t<\/div> \n\t\t<\/div>\n\t<\/div> \n<\/div><\/div>\n\t\t
