Assessment of a Rock Pillar Failure by Using Change Detection Analysis and FEM Modelling

In this paper, various methods have been used to control and evaluate engineering difficulties in mining accurately. Different unstable scenarios occurring at the surfaces of underground mine walls, identified by comparing 3D terrestrial laser scanning surveys subsequent point cloud analysis. These techniques, combined with a change detection analysis approach integration rock mechanics’ modelling, represent an asset for assessment management risk mining. The can be as industrial processes well identify valid model establishing possible failure causes. A pillar spalling has Italian marble quarry topic represents basis present paper. Finite-Element Method was verify occurrence relatively high-stress concentrations pillar. FEM modelling revealed that stresses proximity may sufficient magnitude induce cracks growth failure.
