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. These are new pro duction sites with comparable geological formations along the southern part of the quarry where three planar failures were previously observed.
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 stability of opencast mine slopes is important for the safe and economic mining operations. 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 ...
Feb 01, 1986· In this Paper, the results of monitoring for 1 yr and the back analysis of the slope failure at Kagemori quarry are described. The monitoring of such progressive failure provides an interesting background in a case study of rock slope failure. KAGEMORI QUARRY Geology There are many limestone mines on the outskirts of Chichibu City (Fig. 1).
Surface mining portion covers rock mass characterization, failure modes of slopes excavated in rock masses, probabilistic and deterministic approaches to design of slopes, and remedial measures for slope stability problems. Prerequisite: MN321 or equivalent. 3 hours lecture; 3 semester hours.

Failure surface (shear strain localization) The potential slip surfaces of the examined model are discussed in terms of shear strain localization (Figure. 4).
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 ...
This paper aims to provide a slope stability analysis for the southern part of Wuchangping mine. The methods of limit equilibrium analysis, finite element simulation and neural network were used to study the stability of the southern slope. The preventive measures, such as bolt reinforcement, drainage system and so on were carried out. The results are as follows.

Slope Stability Issues in the Opencast Limestone and Iron. The practical approach to slope stability is guided by the basic geological data geotechnical 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
FHWA NHI-06-088 6 – Slope Stability Soils and Foundations – Volume I 6 - 3 December 2006 6.1 EFFECTS OF WATER ON SLOPE STABILITY Very soft, saturated foundation soils or ground water generally play a prominent role in geotechnical failures in general. They are certainly major factors in cut slope stability and in
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 of stress and strain ...

The term slope refers to an inclined surface or hill slope. Generally it is the area between a watershed (or drainage basin divide) and the base of the slope. Slope form is the shape of the slope in cross section. Slope evolution is the development of slopes over time (how they change) Slope processes are the activities acting on the slopes ...
The results of the calculation of slope stability safety factors at the study site have different results, for Block T-03, slopes with an overall height of 21 m, the overall slope angle of 27 ° has a FK value = 1.502. Block W-06, Slope with an overall height of 25 m, the overall slope angle of 27 ° has a FK value = 1.504.
Jun 18, 2020· In this study, the objective was to develop a new and highly-accurate artificial intelligence model for slope failure prediction in open-pit mines. For this purpose, the M5Rules algorithm was ...
The safety and stability of waste dump are vital influencing factors to the mine sustainability and mine employees. Based on a real mine project in a certain open-pit mine waste dump in Tibet, the in situ test on waste rocks from waste dump, including measurements of density, water content, rock size, and natural repose angle, was conducted. Afterwards, these sample waste rocks, of which grain ...
