Abstract
The paper studies and analyses the induced displacements and slide failures around a broad area of an open excavations in lignite mine in Ptolemais basin in northern Greece. Significant ruptures and horizontal displacements were observed 600 m westwards from the open pit, where the village of Mavropigi is located. A significant number of houses in the village have sustained damages. The causes of the ground movement and their probable connection with the open excavations of the lignite mine were investigated. The slide phenomena are located inside marly formations. A numerical analysis, based on the engineering geological model, was performed to simulate the deformations and the shear and tensile failures and to evaluate the exact mechanism of failure. These displacements and local slide failures are clearly connected with the exploitation of the open pit lignite mine.
