... Abstract Bench blasting is the most common method of rock excavation in productive quarries. Properties of the rock mass and the discontinuities are factors that influence rock fragmentation but cannot be controlled. In this study, the remote sensing techniques known as Terrestrial Laser...

The proposed workflow uses double-nested mean-shift clustering and region growth to extract discontinuity surfaces from point clouds. Discontinuities traces can be extracted from image data using a hybrid...

Abstract In the current practice on rock mass classification in Singapore, the weathering grade is commonly used to determine rock mass classes with some consideration of strengths and discontinuities based on visual examination of rock cores.

The numerical analysis reveals that when the groundwater rises and reaches the height of a discontinuity (the boundary between the rhyolite and the granite), the water...

Results are promising in term of applicability, even if a better estimation of the shear strength parameters of the discontinuities involved in the failure mechanism can be necessary for local fine tuning. natural gas storage asian rock...

... Abstract The influence of infilling material on rock samples often becomes a problem in determining the shear strength. In fact, discontinuity such as joint is often encountered in rock mass. The presence of discontinuity will change the behavior of rock mass. This phenomena become worst when...

... Abstract In hard rock, many rock discontinuities such as bedding plane, joint, fissure et al. are distributed, and influence the strength and deformability of rock mass.
