Experimental Investigation of the Influence of Confining Stress on Hard Rock Fragmentation Using a Conical Pick

High geostress is a prominent condition in deep excavations and affects the cuttability of deep hard rock. This study aims to determine the influence of confining stress on hard rock fragmentation as applied by a conical pick. Using a true triaxial test apparatus, static and coupled static and dynam...
