Surface Deformations Resulting from Abandoned Mining Excavations

The occurrence of surface discontinuous deformations in post-mining areas is currently a significant and important problem, due to both the frequency their threat they pose public safety. This paper presents results research concerning possibility sinkhole formation abandoned mining excavations. For purpose assessing condition rock mass disturbed by existence numerous excavations, electrical resistivity tomography investigations were carried out for selected area where was undertaken past at shallow depths many underground workings accessing deposit exist. hazard also analysed theoretically with new original model based on solution A. Sałustowicz’s pressure arch theory.
