Dispositivo y Método para la realización de ensayos que determinan el mecanismo de rotura sobre muestras de roca empleando discos de corte

Device and method for carrying out tests that determine the breaking mechanism on rock samples using cutting discs (21). The displacement of the cutting disc (21) on the rock sample follows a curved path equal or proportional to that of a cutting disc coupled in the cutting head of a tunnel boring machine on the excavation face of a rock mass. With the use of two discs (21) simultaneously the influence of the interaction of the cracks induced by each disc is also checked. Applicable in the sectors in which they design, produce or use devices that use cutting discs for rock excavation, as is the case of the tbm, in order to help a better optimization of the underground excavation thanks to the previous analysis of the rock break mechanism.
