The assessment of slope stability and rock excavatability in a limestone quarry Kadir Karaman, Bayram Ercikdi, Ayhan Kesimal 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
rock slope stability calculation in limestones. The aim of this study is to investigate slope stability problems for heavily jointed karstic limestones in an aggregate quarry. Limestone quarries have turned into steep cliffs of bare rocks which threaten the safety of construction and have also negative influence on the aesthetics in the Cebeci ...
Abstract. The Cebeci Region is characterised by famous outcrops of Carboniferous Limestone which is mined out for aggregate production. The aim of this study is to investigate slope stability problems for heavily jointed karstic limestones in an aggregate quarry.
Oct 04, 2007· a preliminary method would be Romana''s Slope Mass Rating (SMR), I applied it in situations similar to yours (albeit in smaller faces) with good results. Also, Rocscience ''s Roclab, freeware, gives out a max height for a vertical face given a visual comparison to rock mass classes (GSI method, an evolution of Bjieniawski''s RMR).
At present, the research on the stability of the high cut slope mainly focuses on the longterm safety and stability of the rock slope caused by unloading after the excavation of the rock mass [1–3]. However, the dynamic stability analysis of the slope under the action of blasting load is still in the exploration stage, and there is still a ...
static and dynamic stability of slopes of earth and rockfill dams, slopes of embankments, excavated slopes, and natural slopes in . soil and soft rock. Various methods are available for slope stability analysis. This paper aims an overview on various methods of slope stability on the basis of assumptions, Factor of safety
The selection of the blast damage zone thickness T for the HoekBrown (HB) criterion is significant in open pit slope design and stability analysis. Traditional slope stability analysis adopts a single value of blast damage factor D for the entire rock mass, leading to the underestimation of slope stability. In this research, the parallel layer model (PLM), in which the rock mass is divided ...

Stability analysis of a rock slope requires assessment of shear strength parameters, that is, cohesion (c) and angle of internal friction of the rock mass. Dilatancy in a rock mass is unconstrained near slopes as normal stress on joints is small due to weight of the wedge.
The assessment of slope stability and rock excavatability in a limestone quarry. 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. ... The excavatability of the limestones was also assessed in association with the ...
Based on field observations, the slope angle in the area is dominated by steep slopes. The rock hardness level is dominated by hard rock with a hardness ranging from 50100 MPa. Rock Mass Rating shows that the are a is dominated by good rocks. While the S lope Mass Rating calculation show that the maximum slope angle is between 5275 ° .
Slope stability analysis is performed to assess the safe design of a humanmade or natural slopes ( embankments, road cuts, openpit mining, excavations, landfills etc.) and the equilibrium conditions. Slope stability is the resistance of inclined surface to failure by sliding or collapsing. The main objectives of slope stability analysis are finding endangered areas, investigation of ...
5. Stability Analyses of the Mine West Slope . Introduction . Today, there are several methods for slope stability analysis, each has its own advantages and disadvantages. Numerical analyses methods are the most common ones that are used for rock and soil slope analyses. One of the software''s that can analyze rock slope stability in a nu
SLOPE STABILITY 1. Purpose. This engineer manual (EM) provides guidance for analyzing the static stability of slopes of earth and rockfill dams, slopes of other types of embankments, excavated slopes, and natural slopes in soil and soft rock. Methods for analysis of slope stability are described and are illustrated by examples in the appendixes.

computer calculations, results can be verified by hand calculations using a calculator or a spreadsheet program, or using slope stability charts. An approximate check of calculations can also be performed using the Ordinary Method of Slices, although the OMS will usually give a lower value for the
mechanism that is independent from those parameters. For example, intact rock strength is used to calculate the stability rating while a slope is unstable because of sliding on a discontinuity with a thick clay infill and hence intact rock strength is of no importance for the stability or instability of the slope.
Slope stability is the process of calculating and assessing how much stress a particular slope can manage before failing. Examples of common slopes include roads for commercial use, dams, excavated slopes, and soft rock trails in reservoirs, forests, and parks. Considering the importance of slope stability to their work, it''s beneficial for civil engineers to understand how to
