rocks studied was estimated by the saturation and caliper technique, which was defined by the International Society for Rock Mechanics (ISRM). The Bond crushability index, uniaxial compressive strength, elasticity modulus and dry density of the rocks studied are shown in Table I. Generally, there are three Bond indices: ball, rod and crushability.
