Stability And Long-term Monitoring of Large Excavated Rock
Aug 25, 1999 · This paper investigates the mechanism of slope displacement, the effectiveness of stabilization measures, using the results of long-term monitoring of the unstable behavior of two large excavated rock slopes with elevation differences of about 300 m. The study also evaluates the influence of joints on slope behavior through numerical analysis.

Stability analysis of a high excavated slope. - Free
Jan 01, 2005 · The slope may be stable state if the stratum tilt direction is opposite to the excavated slope's dip. However, many excavated slopes are unstable because of the identical tilt direction of the stratum and slope, following a disadvantageous excavation, without retaining structures, as shown in Figure 2. and Figure 3.

Slope failure and stability investigations for an open pit
Dec 06, 2021 · Slope stability is the key element in determining the geometrical values for open pit mines. The increasing quality of rock masses increases the amount of overall slope angles that cause decreases in production costs. The geological and hydrogeological domain of the open pit mine site is the main source for slope stability investigations.

DESIGN OF STABLE SLOPE FOR OPENCAST MINES
This method of slope stability analysis is not widely used since it has been found that plane surfaces of sliding are observed only with very steep slopes, and for relatively flat slopes the surfaces of sliding are almost always curved. EXAMPLE Referring to Fig. 4.2 H = 16m tan i = 2/3 tan θ = 1/3 c = 10kPa φ = 35˚

Factor of safety of strain-softening slopes - ScienceDirect
Jun 01, 2020 · Stability of soil and rock slopes has long been a subject of study in geotechnical engineering with applications in civil and mining projects. The most common indicator of slope stability is the factor of safety (FOS) defined as the value by which the shear strength of the slope material must be divided in order to bring the slope to the point

Slope failure incidents and other stability concerns in
Nov 01, 2019 · In an interesting recent study, Kavvadas et al. (2018) investigated the stability of slopes in the PPC lignite mines and they stated that slope instabilities are usually governed by sliding along a sub-horizontal, unfavorably sloping (towards the excavation), interface between lignite and an underlying stiff, high plasticity clay or marl layer
