Abstract
L'invention porte sur un procédé et un appareil d'abattage par explosifs de roches dures à l'aide d'un matériau énergétique fortement insensible se mettant à feu à l'aide d'une décharge électrique d'énergie modérément élevée causant le fractionnement et l'éclatement de la roche. L'appareil d'abattage par explosifs (10) comporte une sonde d'abattage réutilisable comportant une électrode (44) à haute tension et une électrode de retour à la terre (46) séparées par un tube isolant (40). Les deux électrodes et la sonde d'abattage (14) sont en contact électrique avec un volume ininterrompu (70) du matériau énergétique fortement insensible, mais néanmoins combustible, tel que le mélange d'une poudre métallique et d'un oxydant. Les particules de métal dans le mélange de poudre métallique et d'oxydant forment plusieurs chemins de métal fusible entre l'électrode haute tension (44) et le retour à la terre, quand elles sont soumises à un courant fourni par une importante rangée (16) de condensateurs reliée à l'électrode haute tension (44). Les différents chemins agissent assez comme une fusée en ce sens qu'ils offrent une résistance électrique suffisamment élevée pour permettre de faire passer l'énergie de la rangée (16) de condensateurs dans le mélange de poudre métallique et d'oxydant, y créant une dissipation élevée de chaleur qui y amorce une réaction exothermique produisant des gaz à haute pression qui fracturent la roche environnante.
