... ABSTRACT: In April 2013, Rio Tinto Kennecott Copper's (RTKC) Bingham Canyon Mine experienced what is arguably the world's largest ever in-pit slope failure. The failure initiated on the East Wall, along a major, continuous, low-strength bedding fault, named the Manefay bed, and comprised...

... ABSTRACT: Pit slope failure can have devastating effects on safety of personnel and equipment, and affect profitability of mining operations. Discontinuities, groundwater, rockmass strength and pit geometry can cause slope failure. Also, mining activities (such as drilling and blasting) can...

... technology in slope monitoring manages to solve slope failure challenges, however there is also need to optimise costs such that the most effective less costly technologies are implemented. In this light, this study highlights the practical applicability of different slope monitoring technologies including...

... Abstract: There have been some earthquake induced failure instances in open pit slopes, none of those were significant to be recorded as causing operational interruptions or injuries. However, there have been a significant number of natural rock slope failures due to earthquakes. This paper...

... sharp slope cut suffers from slope failures, rockfalls incidents, mainly in rainy seasons. The igneous rock masses are medium quality. The 40 m-height rock slope-cut along the road has no benches. The steep man-made rock slope cut is very close to the road, forming a potentially source for rockfalls...

... slope failures occurred at the Hsien-du-shan rock avalanche due to the geometry of the sliding surface. The sliding rocks and soils can be briefly divided into two groups. The computational results fit well to the local information, which two giant bursts were heart during the slope failure. However...

... Abstract: Stability of rock slopes primarily depends upon the orientation of discontinuities with respect to orientation of the slope face. The method of analyzing potential modes of rock slope failure, due to the presence of unfavorably oriented discontinuities, is known as kinematic...

... Abstract: Many recent earthquakes caused many large scale rock slope failures, some of which are wrongly named as landslides. The scale and the impact of rock slope failures are very large and the form of failure differs depending upon the geological structures of slopes. First the author...

... ABSTRACT: A great attention has been given to construct a number of descent roads, at the Kingdom of Saudi Arabia government development plans. Werka descent constructed two years ago and recently harmed due to rainstorm. Werka mountainous road subjected to rockfalls, manmade slope failures...

... 15 meters deep from the surface. Recent slope failure indicated that some parts of the clay curtain are not functioning and not preventing the water inflow to the pit (Fig.2). This can be observed from excessive water inflow after the slope failure. Recent water inflow to the pit is 7.965 m3/day/m...

... ABSTRACT: In this paper, the numerical manifold method has been extended to simulate the practical rock slope failure process. The Mohr-Coulomb criterion with a tensile cutoff is employed to predict the crack initiation and propagation. A cover-division strategy is adopted to realize...

... ABSTRACT: Extensive field studies show that the occurrence of deep-seated slope instabilities (i.e rockslides) is influenced by the discontinuity network and its intersection in relationship to the slope orientation. Furthermore in similar rock types slope failure can develop even...

... components of the risk equation. Methods such as fault and event tree analysis are used for this purpose. The approach includes four main tasks: (1) Evaluation of the total probability of failure (POF) representative of the stability conditions of slopes. (2) Evaluation of the consequences of slope failure...

... the final stages of mining. It usually is done by double-benching at the bottom of the pit, allowing more ore to be exposed for mining at a cost much less than the expense of stripping. However, slope steepening increases the likelihood of slope failures, which can offset the expected gains, and also raises...

... ABSTRACT: Several sliding failures were occurred in the rock slope, composed of the Precambrian metamorphic rocks with large fault system. Fault zone has been known for a main factor affected rock slope failure. Generally, fault material (eg. fault clay, gouge and etc) and fault surface (eg...
