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 Region.

A Coal Mine Dump Stability Analysis A Case Study

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.

However during the mining activities, the stability of

REPORT ON FEASIBILITY-LEVEL PIT SLOPE DESIGN …

The risks associated with slope development increase with inter-ramp slope height. It is common practice to break steep inter-ramp slopes with a ramp or stability bench at intervals of 200 m to 250 m to mitigate these risks. Opportunities Steeper slope angles may be feasible by optimizing these slope designs based on the documented

Slope Stability Issues in the Opencast Limestone and Iron ...

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 …
