MICROFRACTURE BENEATH BLUNT DISC CUTTERS IN ROCK. TECHNICAL NOTE

In this study, a blunt disc cutter, based on a commercially available design, was tested in simulated array. Significant subsurface crack interaction and crater development were observed to occur up to a maximum spacing/penetration ratio of 40.
