The invention relates to a method of generating cracking and to a breaking device. With a drilling unit (12) of the breaking device (4) a drill hole (30) is drilled in a block (5), after which the drilling unit is indexed away from the drill hole, and a cracking unit (13) is moved to its place. During the indexing, a frame (24) of the breaking device is kept immovable relative to the drill hole. The indexing is performed by means of an indexing actuator (28, 59) and in the control of at least one support member (26, 59) along a predeterminedpath of movement (L, R). The breaking device is an independent supplementary device and comprises a control system of its own, which is independent from the work machine.
L'invention porte sur un procédé de génération de fissuration et sur un dispositif de fracturation. A l'aide d'une unité de forage (12) du dispositif de fracturation (4), un trou de forage (30) est foré dans un bloc (5), après quoi une unité de forage est indexée à distance du trou de forage, et une unité de fissuration (13) est déplacée à sa place. Lors de l'indexation, un cadre (24) du dispositif de fracturation est maintenu immobile par rapport au trou de forage. L'indexation est réalisée au moyen d'un actionneur d'indexation (28, 59) et sous la commande d'au moins un élément de support (26, 59) le long d'un trajet prédéterminé de mouvement (L, R). Le dispositif de fracturation est un dispositif supplémentaire indépendant et comprend son propre système de commande, qui est indépendant de la machine de travail.
