In order to analyze the slope stability in open-pit mines, the structural parameters of rock mass such as persistence and spatial orientation of discontinuities are characterized through field surveys, which involve spending high costs and times as well as posing high risks of rock toppling and rock fall. In the present work, a new application of terrestrial digital photogrammetry is introduced...
slope stability is one of the major and determiner parameters in the economy and safety of open pit mines. failure and consequently rupture of the slope caused no compensable economic and humanity losses. so, probability assessment of the further failure for presentation of damages and additional costs is of prime importance. in this research, stability analysis and probability assessment of th...
Rock fracture and its failure with time due to external forces other factors such as fluids, temperature have always been a major concern in rock engineering construction. Based on thermodynamics theory of solid physics, authors propose an energy criterion for rheological rock, which considers two effects: (1) dissipation reduces strength rock; (2) confining pressure increases rock. Subsequentl...
Abstract Rock bolts have been used in the mining industry for a long time. They are as reinforcement tendons to keep stability of openings underground and slope open-pit mining.
Time series of dilatometric measurements of relative displacements on rock cracks on stable and unstable sandstone slopes were analyzed. The inherent dynamics of rock slopes lack any significant nonlinearity. However, the residuals obtained by removing meteorological influences are fat-tailed non-Gaussian fluctuations, with short-range correlations in the case of stable slopes. The fluctuations...
