Abstract

L'invention concerne un procédé (400) de rupture de roche, le procédé (400) consistant à : réaliser (401b) une ou plusieurs indentations sur une formation rocheuse (700) dans le sol par l'utilisation d'un dispositif d'indentation (200) de façon à produire une réponse d'indentation, le dispositif d'indentation (200) comprenant un ou plusieurs capteurs (208, 210) ; comparer (402) la réponse d'indentation produite à des réponses d'indentation précédemment déterminées associées à différentes catégories de roche avec une ou plusieurs propriétés ; et, sur la base de la comparaison de la réponse d'indentation produite aux réponses d'indentation déterminées précédemment, déterminer (403) la catégorie de roche de la formation rocheuse (700) et ainsi une ou plusieurs propriétés de la roche de la formation rocheuse (700). L'invention concerne en outre un système (300) de rupture de roche. Le système (300) comprend : un dispositif d'indentation (200) destiné à effectuer une ou plusieurs indentations sur une formation rocheuse (700) dans le sol ; et un arrangement de commande (130) destiné à mettre en œuvre le procédé.
