Abstract

L'invention concerne un tampon explosif pour trou de mine, qui comporte un corps tronconique en matériau flexible, et un coeur en matériau dur, également de forme tronconique. Une vis permet de remonter le coeur dans le corps pour comprimer celui-ci contre la paroi du trou de mine. Ensuite, une explosion dans le trou de mine poursuit la poussée du coeur vers le haut et assure la mise en place d'un tampon explosif efficace.
