... with an orientation parallel to the orebody. A significant variation of the rock mass behaviour is present around the mine. Although high seismic events are recorded in certain areas, the presence of the foliation under high stress results in highly 13th International Congress of Rock Mechanics ISRM13 10-13 May 2015...

... Abstract The kinematic analysis of rock blocks is one part of a block stability assessment. It provides information about a block's movability, i.e. if a block can detach from the adjacent rock mass and move towards the free space. This paper introduces an analytical method for the analysis...

... Abstract A major consideration in the design of high capacity tiedown anchors for dam, bridge and tower foundations is the tensile resistance of the rock mass to pullout, typically as a result of overturning moments or hydrostatic uplift. Rock mass pullout capacity for installed anchors...

... Abstract In the presence of joint sets sub-parallel to a slope face, the stability of the rock mass is controlled by the shear strength of the joints. On one hand, if the joints are persistent their shear strength can be assessed according to Mohr-Coulomb criterion, assuming appropriate values...

... Abstract This paper is aimed to confirm the possibility to excavate fractured rock masses by using EPB shields, even in presence of relevant water tables. This verification is based on laboratory test experiences carried out at TUSC laboratory of Politecnico di Torino, where the natural...

... on slope stability, mainly assuming homogenous materials with a circular shear-failure mechanism. However, many open pit mines are excavated in jointed rock mass where a completely different set of failure mechanisms can be seen. Depending on the geometry and radius of the pit, the curved geometry may...

... energy, after sudden removal of one single pillar, mainly depends on three parameters: the initial extraction ratio of the mine, the depth of the exploited seam and the Young's modulus of the surrounding rock mass compared to that of the ore. Moreover, it is pointed out that the magnitude of the seismic...

In this study, a discrete element modeling was performed in order to represent a transversely isotropic rock such as shale, and the upscaled model was applied to foundation and borehole problems using PFC2D. The applicability of the upscaled rock mass model was verified...

... model rock mass Abstract It is well known that Peak Particle Velocity (PPV) plays a critical role in triggering rockburst damage in burst-prone underground mines. To estimate the PPV distribution around excavations, advanced numerical modeling can be used. In wave propagation numerical modeling...

... Abstract Calcite-cemented joints abound in the rock masses of Beishan area, which is the most potential area for the high-level radioactive waste (HLW) disposal of China. The mechanical properties of Beishan granite containing a calcite-cemented joint with a dip angle of 82° was investigated...
