Isikdere open pit mine has been operating since late 2009 by the Turkish Coal Enterprises to provide lignite for a thermal power plant. The technical objectives of this study are to evaluate stability of the final pit slopes and to recommend necessary modifications on the current pit project and remedial measures. The analysis results indicate that stability of the final pit slopes is sensitive to multiplanar failures and pressurized water in the coal seam is also another factor adversely affecting the stability. Problems associated with groundwater at the site were also assessed with the analyses of piezometric level and groundwater inflow. Remedial measures investigated suggest that at some parts of the pit, original project should be modified by flattening or shifting the final slopes towards north or stripping them to a certain elevation.
