This paper presents examples of several scenarios in which pit slope stability assessment may be required at mine closure. These are focused specifically on the longterm stability of the open pit excavations, not the stability of any adjacent structures. The paper does not attempt to propose a set of guidelines but discusses techniques that may be used for assessment under various scenarios.
Fatalities caused by highwall/spoilbank failure in the surface mines, coal and nonmetal, increased to an alarming rate of seven during 1999. To determine the cause of slope failure and successful mining practice, the National Institute for Occupational Health and Safety undertook a study.

What is the factor of safety and how does it apply to slope stability? In what ways does water added to a slope affect its stability? Define the following (a) angle of repose, (b) sensitive soils, (c) hydrocompacting clays, (d) groundwater, (e) quick clays ; What kinds of rock structures can reduce the stability of slopes?
This paper aims at examining how the data for the geomechanical properties of slope material and for groundwater condition can be precisely and quickly collected, evaluated, and best used for optimum slope design in a block of phosphorite in an open cast mine.
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.
