Abstract
ABSTRACT Spoil pile instability has been a continuing problem in the lignite coal mining operation in Orhaneli, Türkiye. The important factors controlling the spoil pile failures were found to be up dip dumping, high groundwater level, weak layers within the mine footwall and spoil piles reaching up to 50 m height. Stabilization methods analysed involved decreasing effective spoil height in various ways, removing weak layers within the footwall, supporting the toe of spoil pile, improving groundwater conditions. Stability has been evaluated by carrying out 2-dimensional circular failure analyses.
