ABSTRACT

Çan Lignite Establishment belonging to T.K.I (Turkish Coal Enterprises) has been operating an open pit over two decades. Three years ago, the boundary of the open pit came close to one of the biggest Ceramic Factory in Turkey namely (Çanakkale Ceramic Factories. Since the beginning of the coal extraction in the area, small scale slope failures including several benches have been observed. But in 17 August 1999, due to catastrophic earthquake centred in Gölciik, huge amount of material started sliding. Bigger size of landslide provoked by both the earthquake and activities in open pit mining showed itself with tension cracks in backyard of the Ceramic Factory. This paper introduces the measurement done to define the slip surface then what precautions have been taken to stop slope failure.
