An Experimental Approach to Evaluate the Role of Rock Failure Modes in Mechanical Characterization of Metabasalts

A detailed understanding on rock failure modes testifies the competence of support designs for engineering work. Studying such using physical models specimens under laboratory conditions can be time efficient, informative and economically viable. In this study, mechanical behavior massive metabasalts were characterized with reference to through index tests as point load Brazilian tests. Rock test are categorized (1) single plane, (2) triple junction, (3) twisted (4) plane (inclined) modes. Twisted junction observed in higher strength values (> 6 MPa). total five types testing namely central multiple, central, non-central, multiple + layer activation (5) conjugate Central mode is found most common due their nature. Failure within a range 8 12 MPa. Among all other modes, respectively introduced study. It evident that controlling rocks should considered an important aspect characterization materials.
