3D geomechanical modelling of sinkholes formation: investigating geomechanical consequences associated with mining areas in the Silesian Coal Basin, Poland

The Silesia region in Poland is historically known for its mines. In an era of energy transition, the use of coal as a source of electricity is no longer permissible, and most of the mines have been closed, shutting down the pumps and, consequently, allowing them to flood. The ingress of water leads to a change in pressure, which can lead over time to the formation of sinkholes, an unfortunately world-famous phenomenon. This thesis aims to create a 3D geomechanical model that can simulate what happens underground.
