Crushing Compressive Strength Of Rock

Mar 01, 2010 The compressive strength and crushing time follow an increasing trend and implies that the crush- ing time is directly proportional to the compressive strength of the rocks, that is, the harder the rock, the more the crushing time under the impact of the jaw crusher.

    5.2 Method C, uniaxial compressive strength of rock is used in many design formulas and is sometimes used as an index property to select the appropriate excavation technique. Deformation and strength of rock are known to be functions of confining pressure. Method A, triaxial compression test, is commonly used to simulate the stress conditions under which most underground rock masses exist.
