The fracture strength is given as the maximum stress necessary to induce failure of the rock core. This value gives an indication of the cohesiveness and density of a rock. As seen in Table 1 igneous, metamorphic and sedimentary rocks can be classified from very weak to very strong with regards to their unconfined fracture strengths (Attewell & Farmer 1976). Generally, sedimentary rocks can ...
