SMARTER LIGNITE OPEN PIT ENGINEERINGS SOLUTIONS (SLOPES)
Το έργο SLOPES συγκεντρώνει εμπειρογνώμονες από όλη την Ευρώπη για να προωθήσουν την τρέχουσα τεχνολογία και μεθοδολογίες που εφαρμόζονται στην παρακολούθηση και την ανάλυση κινδύνου των αποθέσεων εντός των ορυχείων λιγνίτη ανοικτής κοιλότητας. The SLOPES project brought together experts from across Europe to advance the current technology and methodologies applied to understanding, analysing, and monitoring slopes within open pit lignite mines. The project targeted three main areas. Firstly, the research evaluated how modern monitoring techniques can be applied and integrated within automated systems that provide ‘real-time’ assessments of risk. A particular focus was the potential use of unmanned aerial vehicles because of their versatility and that they reduce the need to have people and equipment in hard to access and potentially dangerous areas. Secondly, the project conducted a variety of stability analyses of open-pit rock-face slopes. Advanced probabilistic analyses were developed, giving improved methods for evaluating the performance and potential risks associated with open-pit slope faces. Advanced numerical modelling techniques were applied to gain an in-depth understanding of the behaviour of the slope faces, as well as an assessment of the potential vulnerability of mining and other nearby infrastructure. Finally, the project studied the long-term behaviour of lignite mine spoil materials, with particular attention on stability and ground movements within spoil heaps and reclaimed ground. A rigorous approach involving laboratory testing of soils, small-scale physical modelling (including elevated gravity modelling using a geotechnical centrifuge), and numerical/probabilistic modelling was applied. The project outcomes will enable development of effective reliability-based methods for the evaluation of risks based on monitoring and modelling results which will provide significant benefits to design optimisation and decision support within open-pit lignite mines.
