Real-scale fragmentation tests provide high quality data in order to study the pattern of rock blocks. In carried out, initial mass, terms both volume and shape, was reconstructed by means 3D photogrammetry. The fragments size distribution bocks tested measured hand using a tape. drop were performed four different sites, releasing total 124 blocks measuring 2907 fragments. obtained fragment distributions may be well fitted power laws. survival rate (Sr), which is proportion remaining block shows wide range values. Observing distribution, two parameters are needed characterize fragmentation: number produced Sr. intensity expressed exponent Although results highly variable show stochastic behavior fragmentation, we have identified patterns that reflect some local test conditions.
