“…It must be emphasized, however, that the time needed for data processing are significantly longer when dealing with accurate and detailed slope geometry and that such detailed data is useful in complex cases but may be unnecessary in simple slopes where a large scale topographic map can still be suitable (Francioni et al, 2014). Havaej et al (2016) clearly showed the advantages of using terrestrial photogrammetry and LIDAR in developing DFN for a slate quarry slope at Delabole, Cornwall, UK. slope failure mechanisms, the results agreeing with observed slope behaviour.…”

“…Stead (2009a, 2009b) highlighted the importance of understanding possible bias related to the use of this technique and how the results can be affected by occlusions. Nevertheless, this method has been successfully used by several authors in the analysis of rock slopes (Haneberg et al, 2006;Bonilla-Sierra et al, 2015;Havaej et al, 2016). In the following sections, the most common types of platform for slope surveys are presented.…”

“…Pre-existing discontinuities and their orientation, in relation with the orientation of excavation, determines the possible kinematic instability mode: some case studies regarding different kinds of quarry are reported in [38][39][40][41]. Stability conditions are further affected by discontinuity persistence in the form of rock bridges that can increase the available shear resistance [42][43][44].…”

“…The peak metamorphism, estimated at 350-450 • C and 0.6 GPa [49], was reached during the early D1 phase and was dated at~27 Ma (K-Ar and 40 Ar- 39 Ar on white mica [51]). The D2 event is responsible of the formation of a complex mega-antiform with Apenninic trending axis (NW-SE) during the exhumation of the metamorphic units [48,52].…”

The use of non-contact-techniques for rock mass characterization has been growing significantly over the last decade. However, their application to stability assessment of ornamental stone has not yet received much attention from researchers. This study utilizes rock mass data both in terms of slope orientations and degree of fracturing obtained from a point cloud, a set of three-dimensional (3D) points representing a rock mass surface, to (1) investigate the influence of geostructures at different scales and (2) assess quarry stability by determining areas susceptible to different failure types. Multi-resolution point clouds are obtained through several photogrammetric survey techniques to identify important structural elements of the site. By integrating orientation data of discontinuity planes, obtained with a traditional survey, and of traces, outlined on point clouds, several joint sets were identified. Kinematic tests revealed various potential failure modes of the rock slope. Moreover, an analysis of the influence of the discontinuity strength determined by the presence of rock bridges was carried out. The study revealed that the strength of the quarry face is governed by the presence of rock bridges that act to improve the stability condition of the rock fronts.

“…Pinnaduwa et al [13] incorporated field deformation monitoring data with 3D numerical modelling (with 3DEC) in order to predict the rock mass deformation in an open pit mine. The study conducted by Havaej et al [14] offers an excellent practical example of calibrating a 3D numerical model (using 3DEC code) of a slate Energies 2020, 13,1913 3 of 23 quarry. The authors calibrated their numerical model with the data obtained from the laser scanning of a portion of the mine.…”

The Challenges of Open-Pit Mining in the Vicinity of the Salt Dome (Bełchatów Lignite Deposit, Poland)

The extraction of the Bełchatów lignite deposit located in the vicinity of the Dębina salt dome requires careful planning that considers the influence of mining projects on the slope and salt dome stability conditions. The instability problem is directly related to horizontal and vertical displacement, as well as the complex geological and mining conditions. These conditions are very unique with regard to the co-occurrence of the salt dome and lignite deposits in the same area, as well as the large scale of the pit wall slope. Thus, predicting rock mass behavior and ensuring the safety of mining operations are important issues. The presented analysis focused on the influence of long-term lignite extraction on the western pit wall slope of the Bełchatów field and the salt dome’s stability conditions. This study offers a comprehensive approach to a complex geotechnical problem defined by large-scale, complex geometry, and geological conditions. The rock mass behavior and stress conditions are simulated in numerical modelling. The results of the presented analysis will be useful not only for present mining activities but also for future developments related to post-mining and recultivation plans.
