ABSTRACT: As open pit slopes continue to increase in depth, new approaches to characterising rock slope masses and slope failure mechanisms are required; these approaches should integrate and optimize new developments in remote sensing and geomechanical modelling. The author presents the state...

... with geotechnical parameters allows calculating of well-known safety factors for slope failure in rock and soil. Furthermore, the effect of water availability on slope stability can also be taken into account and is useful to estimate the effect of long-term precipitation events on slope stability. The calculated...

A complete description of these mechanisms is presented by Ramírez and Alejano (2007) All such failures require that the main joint family is parallel to the excavated slope. An interesting, less known case arises when. i...

..., or complex sliding. Özgenog lu (1986) also investigated slope failure either containing a slide plane or not. In slope analysis, slope environments are classi- fied as discontinuous (i.e., discontinuities bearing rock mass), semi-continuous (i.e., loosened rock mass or rock fill), and continuum media (i.e...

... Abstract Slope stability in open pit mines is an important issue. Most open pit coal mines are located in Kalimantan in which rainfall is very high and as such so is the probability of slope failure. It has been well accepted that slope failure risk consists of probability times consequence...

... encountered the swelling problems. The Telnes ilmenite open pit mine in Southwestern Norway and the Goynuk lignite open pit mine in Turkey can be examples for the issue (Nilsen & Ballou 2006, Tabrizian 1989). In these mines swelling rocks caused slope failures. The topic of this study is about swelling...

... ABSTRACT: Modeling of shallow rock slope failures has been undertaken to explore the validity of two commonly used failure criteria for discontinuities. The Mohr-Coulomb (MC) and the Barton-Bandis (BB) joint shear strength models have been examined. The 2-D Universal Distinct Element Code...

The issue of predictability of landslides and rock slope failures, which are major geo-hazards, is of great concern. In the geotechnical field, structures are monitored...

The presence of random and heavy jointing in rockmass and intensive rainfall further accelerated the slope failure. 1...

Thus, it could be concluded that measurement of displacement like this without having so high accuracy could be also effective to monitor an unstable rock mass, if continuous measurement is conducted. 1.
