Abstract

La présente invention porte sur des appareils et sur des procédés de forage à puissance pulsée. Un appareil de forage comporte un trépan équipé d’un ou plusieurs ensembles d'électrodes à travers lesquels une tension pulsée traverse un substrat minéral de façon à créer une action de broyage ou de forage. Le procédé de forage et de broyage électrique peut avoir, mais ne requiert pas, une rotation du trépan. Le procédé de forage et de broyage électrique permet de creuser le trou au-delà des bords du trépan avec ou sans l'aide de dents mécaniques.
