Granite Mining Strength Mpa

Aug 03, 2021

Oct 26, 2021 Meanwhile, the compressive strength of granite is about 100MPa to 300 MPa. The fine granite can reach up to 300 MPa of its compressive strength and 10 MPa to 30 MPa of bending strength. How is granite extracted? How to mine granite rocks The basic mining process of granite includes mountain separation, rock division, and product shaping. 1

    The major principal stress is horizontal with a magnitude of 3.4 MPa, and the compressive strength of the rock types is 53 MPa for the shale and 71 MPa for the basalt. The strength/stress ratio for these two cases is then 53/3.4 = 15.6 and 71/3.4 = 20.9, respectively, and so for both of them the stress reduction factor is 1.0
