Rock breakage by crushing, blasting, and drilling

Although rock strength varies with rock type and increases for a given rock with increased confining pressure, the intercept of the performance line can be correlated with rock shear strength …

Rock Strength

Rock strength is specified in terms of tensile strength, compressive strength, shear strength, and impact strength. In the context of fracture gradient, only the tensile strength of rock is of importance. The tensile strength of rock is defined as the pulling force, required to rupture a rock sample, divided by the sample''s cross-sectional area.
