Goel, in Engineering Rock Mass Classification, 2011 Uniaxial Compressive Strength of Intact Rock Material (qc) The strength of the intact rock material should be obtained from rock cores in accordance with site conditions. The ratings based on both UCS (which is preferred) and point load strength...
Goel, in Engineering Rock Mass Classification, 2011 Uniaxial compressive strength of rock mass Equation 13.3 defines that uniaxial compressive strength of a rock mass is given by (13.6)qcmass=qcsn Equation (13.6) underestimates mobilized rock mass strength in tunnels. To use Eq. (13.3) in ...
Shear strength parameters play a crucial role in the design and construction of rock slopes, underground openings, tunnels, excavations, and foundations. Determination of cohesion (c) and angle of internal friction (φ) through laboratory tests (e.g., triaxial tests) and in situ tests is time-...
The only noticeable exception that explicitly account for rock block defects was proposed by Laubscher and Jakubec (2001) via the Mining Rock Mass Rating (MRMR) classification system which essentially introduced the rock block strength concept (Fig. 2). The MRMR system expresses the RBS of ...

(lherzolite,harzburgite, and dunite) and, in many localities,eclogite. The key to these magmas containing diamond is that as they ascend through the mantle, they fracture and break off meter-sized pieces of the mantle conduit (Fig. 4.4.2). This material disaggregates as themagmaascends, ...
(Smith and Downs1974), which means our data do not support the classification in seven varieties. Naturally fragmented species’ groups are known for their challenges faced during discrimination between intraspecific differentiation and speciation (i.e. Folk and Freudenstein2015; Hedin et al.2015; ...
