Abstract
L'invention concerne un procédé de forage de roches consistant à faire avancer une machine de forage (3) de roches vers une roche (33), à forer une faible profondeur dans la roche à l'aide de valeurs réduites sous une pression d'impact (38) et une pression d'alimentation (36) et, après ces opérations, à augmenter lesdites pressions d'impact et d'alimentation, ce qui permet de terminer le forage du trou. La pression dans un amortisseur de recul (21), au niveau de la machine de forage (3) est lue et stockée dans une mémoire (44). La machine de forage (3) avance vers la roche (33) à l'aide d'un dispositif d'impact tournant inactif jusqu'à ce qu'un outil de forage (2) de roches connecté à ladite machine de forage (3) atteigne la roche. Le déplacement de la machine de forage (3) vers la roche est interrompu lorsque la pression (35) dans l'amortisseur de recul (21) dépasse la valeur stockée en mémoire (44) d'une quantité prédéterminée et que le trou est foré.
