In general, compared to intact rock, a rock mass has reduced tensile strength (almost zero), and reduced shear strength especi ally along discontinuity planes. Further , if a rock mass is cut by directional joint sets , the rock mass strength is anisotropic. Rock mass strength is scale dependent and varies with the volume of rock under.
Rock strength and the normal stress. As the nor-mal stress increases, the asperities are progres-sively sheared off and the total friction angle diminishes (see Section 2.2). Fractured rock mass The shear strength of a fractured rock mass, in which the rupture surface partially lies on fracture surfaces and.
Jun 04, 2020 The crushability test results demonstrated that the DRC in cone crusher could be quantified by focusing on the variations in the SRR and P10. The SRR and P10 are associated with three important rock properties, Shore hardness (SH), Los Angeles abrasion loss (LAA, ), and Brazilian tensile strength (BTS, MPa).
