An important aspect of the Greek surface lignite mines relates to the stability of the corresponding excavations. The more recent ones, over the last few decades, have become larger and deeper (up to 200m) compared to those in the past and, as a resu

A new perspective is presented for evaluating the slope stability of coal and lignite mines due to rainfall. The case of Greek lignite mining areas is employed to illustrate the methodology. Initially, past climatic records of rainfall are documented

This paper attempts to investigate the use of approximate 2D numerical simulation techniques for the evaluation of lignite pillar geomechanical response, formed via the room and pillar mining method. Performance and applicability of the developing me

A reliability analysis framework for the stochastic simulation of slope progressive failure is proposed in the current work. Progressive failure is addressed as a local failure propagation process that takes place along individual segments upon a cri

A methodology for the probabilistic evaluation of slope stability, capable of disclosing local reliability levels for a certain failure mode of an excavated slope, is proposed in the present work. Probabilistic slope evaluation is conducted upon a de

Coal mines produce large amounts of excavated waste soils, known as spoils. These materials can cover vast areas, are typically dumped in heaps without any treatment, and are difficult to exploit for engineering purposes because of their significant

A probabilistic geotechnical design optimization framework for large open pit excavations is proposed in the present work. An appropriate objective function is formulated in terms of normalized cost of excavation, while the overall slope angle consti

The large amount of spoil material produced during the mining process imposes a significant economic and environmental liability on lignite producers. In this context, the present paper provides an overview of the geotechnical characteristics of Euro
