... figure a more representative set of adjectives will be seen, using a new multi-component machine-rock parameter QTBM, which uses the six Q-parameters for rock mass description, and has extra parameters such as cutter force and rock mass strength. 4. Cutter life and the effect of high Q-values and high...

... and for the Fantiscritti site [2,4]: thus the results reported in Table 1 and 2 can be considered as representing an average mechanical characterization for white Carrara (Apuan Alps) marble. Table 1. Average mechanical characterization for Carrara marble: c= uniaxial compressive strength; t= tensile strength; = shear...

... for the implementation of rock mechanical tests (simple compression, diametric compression, triaxial compression and characterization) [1][2][3]. The geological model in Figure 1 and 2 shows that the foundation of the dam on the left margin and riverbed is developed on volcanic rocks of high strength, low deformability...

... Abstract. The disturbance factor (D) included in the Hoek-Brown criterion represents a strength reduction parameter associated to the damage induced in large open pit slopes as a result of the blasting process and also as a consequence of the stress relaxation and stress rotations induced...
