Analysis of Faults' Effect on the Stability of Surface Lignite Mining Areas Using the Distinct Element Method

Mining operations can drastically affect the stability of nearby areas. A representative case for this has been Mavropigi mine, a part an open-pit lignite mining complex in northwestern Greece. is vast excavation that reached 150 m depth and posed severe challenges issues caused problems area. In 2010, noteworthy surface tension cracks appeared near excavation, leading to extensive monitoring countermeasures, while various studies were conducted. The present work aims revisit study from different than previous perspectives. Previous based only on continuum approaches, thus understating or ignoring effect discontinuities. Nevertheless, area intense tectonic past faults interact with soil movements. work, advanced, discontinuous numerical modelling through distinct element method was used understand better role slope-fault interaction assess faults’ area’s response. results emphasised influence ground fault’s existence increases impact mine surrounding significantly intensifies possibility structural damage constructions. analysis confirms mine’s be amplified under geological conditions, case, presence nearly parallel slope inclination.
