Feb 01, 1986· After this accident at Kagemori limestone quarry and publication of the results by the authors (in Japanese [4]), many research projects concerning slope stability have been reported--mainly in the Journal of the Mining and Metallurgical Institute of Japan.
May 30, 2020· The aim of this study is to evaluate the stability and excavatability of newly stripped rock slopes (slope 1 (SN–1), slope 2 (SN–2), and slope 3 (SN–3)) in a limestone quarry.
Abstract: Keeping slope relative stable has very significant meaning for open pit mine in its whole service life. Tangshan ou Mine Corporation is taken for an example to assess slope stability. By application of finite element method and applications with ANSYS software, the analysis on rock slope stability of the mine was carried on, which is based on the calculation .

slope failure, toe failure and base failure (Figure 2). In the slope failure, the arc of rupture surface meets the slope above the toe. This is possible only when slope angle steep and the soil close to the toe possess high strength. Toe failure occurs when the soil mass of the slope above the base and below the base is mainly ho-mogeneous.
Jan 01, 2015· Indian mines 80% mining is open cast and remaining underground mines. So Slope stability monitoring is a vital component in any surface mine and is an essential component for planning deeper and steeper deposits, in terms of economics and safety. Various methods of slope stability monitoring systems have evolved over the last few years.
While less than 1% of reported accidents are associated with slope stability problems, slope failures were responsible for about 15% of all U.S. surface mine fatalities between 1995 and 2001. Small rockfalls, which may involve hand-sized rocks weighing only a few kilograms, can cause fatal injuries to workers away from the
Department of Mining Engineering, Karadeniz Technical University, 61080, Trabzon, Turkey GEOTECHNICS The aim of this study is to evaluate the stability and excavatability of newly stripped rock slopes (slope 1 (SN–1), slope 2 (SN–2), and slope 3 (SN–3)) in a limestone .

The Çiftehan-Pozantı segment of the Ankara-Pozantı motorway is problematic due to the existence of lithological units with variable character. Seven cut slopes are planned along Km 358+000– Km 364+350 of the proposed motorway. The purpose of this study is to determine engineering geological properties of the rocks exposed along the motorway and to assess the excavatability and stability ...

New slope stability considerations for deep open pit mines therefore appropriate that new attention should be paid to the effects of stresses on the stability of the slopes of these mines. In this paper, a brief review of the application of stress and numerical analysis techniques to slope stability is presented.
program, it can be concluded that there is no collapse of the mining of limestone quarrying in the three study sites: Jember, Gresik and Madura district (for height 5 meter until 20 meter height and angle = 50° until angle = 90°) Key words: Slope stability, Open mining, Dynamic load, Wetting-drying, Safety factor, Kab. Madura, Kab. Gresik, Kab.
One specialty is assessment of slope stability and design on scales ranging from civil engineering slopes in soil and rock, including portals, to mine benches and inter-ramps for many of the world's largest open-pit mines. Another is analysis of both the static and dynamic stability of waste dumps, leach piles, and tailings dams.
The practical approach to slope stability is guided by the basic geological data, geo-technical characteristics of the slope mass, ground water details and a good measure of engineering judgment. The paper presents in brief the slope stability studies conducted by the author indifferent Indian opencast mines in limestone and iron ore sectors.
This paper highlights the slope stability analysis of a limestone mine in Tamilnadu state, India. A critical evaluation of the slope has been carried out with the present pit limit of 60 m to a ...
Slope instability can be a potential source of danger for people and equipment, also it disrupt mine scheduling and increase the cost of mining production (Lilly et al., 2000;Kido et al., 2000 ...
The slope stability analysis of rocks is vital for designing safe slopes in open–pit mines. A proper slope design not only leads to improvements in slope stability and safety but also reduces costs, extends the life of mines and decreases the stripping ratio (Bye and Bell, 2001, Naghadehi et al., 2011).
