About this site

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.

Method for Determining the Unconfined Compressive Strength of Intact Rock Core Specimens SC T 39 1. Scope This method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. This procedure is identical to ASTM D 2938 except that the cores are tested after cutting

About this site

Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.

STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES 1

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 consideration. The modes of failure of intact rock are multiple. Rock can fail in tension, compression or shear.

Chapter 4 Engineering Classification of Rock Materials

• hardness and unconfined compressive strength categories unit weight (dry) • unit weight (dry) • color • discrete rock particle size (use D 50 or cube root of the product of its three dimensions) (a) Rock unit identification The rock unit is the basic mapping unit for the rock
