Open Pit SRG Global's Geotech team has extensive experience in undertaking ground support and stablisation works for mining clients. Typical works include wall stabilisation, rockfall protection systems, ramp protection and reinstatement, erosion control, geotechnical instrumentation, mesh drapes and netting, w-straps and cable lacing as well as shotcreting and fibrecreting. The stability of slope is also a very important issue in the process of open pit mining while the vibration mining of blasting has some impact on the stability of dump and slope (Xing, 2004; Zheng et al., 2011; Li et al., 2010; Huang et al., 2011).

Slope stability, or the lack thereof, rests upon the ability of a slope to resist stress excess to what is normally acceptable for the material property of the soil or rock inherent to the construction slope. Slope movements, such as translational or rotational slope

Slope stability assessment is an essential aspect of mining and civil engineering. In this study, Songwe open-pit mine in Malawi was investigated to establish possible pit slope instability. In performing the analysis, an integrated approach entailing rock mass

These include ore grade, metal price, development costs, construction costs, mine design, stability and operating costs. With the great increase in the size of open pits to depths over 600 ∼ 800 meters, the determination of pit slope angle and control of wall stability has a major influence on project economics.

Moreover, open-pit mining is generally preferred in mining operations due to its applicability in all operable areas of exposed rock, minimum production loss and high production rate [], especially for ores such as limestone, granite and iron ore that are exposed at

In engineering projects associated with rock mechanic science like open pit mines, assessment and slope sta- bility of mine walls is one of the important performance in generate of these structures. Estimating and knowledge of stable slope angle is one of main

China has over 1500 open-pit mines and 5000 dumps consisting of waste rock from the mining process. Due to dump instability in an open-pit mine and its diverse foundations, landslides and mudslides frequently occur. Heaped loose waste rock and concentrated heavy rainfalls are the two important factors affecting slope stability of a dump. Using the high Dump II within the Nanfen Open-Pit Iron

The Aitik open pit mine, located in northern Sweden, currently faces a substantial production increase, Detailed analysis of the large-scale slope stability showed that a steepening of both the interramp and the overall slope angles was possible (Sjberg, 1999

actual slope failure in open pit mines during earthquakes has been reported in the literature. In the last ten years studies into the influence on stability were carried out by investigators like Seed (1970), Goodman et a1 (1966), and others. Laboratory test

Surface deformations and slope stability are very important issues to the open pit mining industry. Slope and batter in-stability can be a potential source of danger for people and equipment. It may also disrupt mine scheduling and increase the cost of mining

Open-pit mines are also special in the sense that extraction must respect slope con-straints: in order to reach blocks by digging from the surface, there is a minimum set of blocks that have to be extracted before. Indeed, the shape of the pit must be such that

In the concept of mining a deposit, mining operations should be planned and organized in order to maximize the productivity. Slope stability issues directly affect the productivity. It's for these reasons that they need to be addressed with theoretical and technical expertise. And the realization of a surface mine, 3 fundamental processes should be taken into account. The first one is the
