Combining Satellite InSAR, Slope Units and Finite Element Modeling for Stability Analysis in Mining Waste Disposal Areas

Slope failures pose a substantial threat to mining activity due their destructive potential and high probability of occurrence on steep slopes close limit equilibrium conditions, which are often found both in open pits waste tailing disposal facilities. The development slope monitoring modeling programs usually entails the exploitation situ remote sensing data, together with application numerical modeling, it plays an important role definition prevention mitigation measures aimed at minimizing impact areas. In this paper, new methodology is presented; one that combines satellite radar interferometry 2D finite element for stability analysis regional scale, applied within unit polygons. Although literature includes many studies applying analysis, addition units as input data purposes has, our knowledge, not previously been reported. A former area southeast Spain was studied, method proved useful detecting characterizing large number unstable slopes. Out 1959 used spatial 43 were unstable, varying values safety factor landslide size. active units, 21 exhibited line sight velocities greater than maximum error obtained through validation (2.5 cm/year). Finally, work discusses possibility using results proposed approach devise proxy hazard. can help provide non-expert final users intelligible, clear, easily comparable information analyze instabilities different settings, limited
