Slope stability risk assessment on structures of a nearby residential area around a surface lignite mine in Bursa-Turkey

2012-05-28
Slope failures may cause production interruption and equipment loss in addition to the potential danger for personnel. A potential instability in parts of the slopes near residential areas may result in damage on the surface utility structures as well as legal issues. In Orhaneli Surface Lignite Mine, Altintas village is located close to the existing southwest slope of Panel SA-6 in Sagirlar Sector. South-east slope which is also near Altintas village had some slope stability problems. Safe and uninterrupted future production in Sagirlar SA-6 panel and assessment of the preventive measures to protect the structures of Altintas Village are the main targets in this work. Potential for a possible slope failure and its effects on structures of Altintas village are assessed and some remediation measures are proposed. Remediation suggestions are predicted to increase safety against effects of a potential slope failure. Potential risks are evaluated by means of comparing safety factors which are determined by modeling the different slope geometries and preventive measures with a program using limit equilibrium methods. Slope stability analyses in this work are conducted by Rocscience SLIDE program which is a method of slices program based on the limit equilibrium techniques. Optimum slope geometries for different production directions and alternatives are investigated and alternative solutions for the improved safety of mine operations and nearby structures of Altintas Village are assessed.
