Stability calculation and analysis of high and steep slope with complex fault structure
Complex fault structures pose significant hazards to mining safety,underscoring the importance of stability analysis,safety assessment,and management of open-pit slopes in both domestic and international mining research.This study focused on the southern slope of the primary mining area at Baiyun Obo iron mine,conducting thorough investigations and research into geological challenges such as dense reverse complex faults,localized instability and landslides on steep slopes in the region.The numerical simulation analysis and Short Baseline Subset Interferometry(SBAS-InSAR)technology were used in the study,which could accurately predict areas prone to slide and provide precise evaluations of slope stability.The potential hazard zones were searched by three-dimensional numerical model,and further analyzed by detailed two-dimensional profiles.Additionally,SBAS-InSAR technology was employed for temporal monitoring of surface deformation,accurately measuring minor changes through radar image phase analysis,thereby validating the reliability and effectiveness of numerical analysis.By integrating these two methodologies,this paper comprehensively assesses the slope stability of the southern slope in the main mining area of Baiyun Obo iron mine,effectively mitigating and preventing losses from geological disasters.It also serves as a valuable reference for stability analysis of high steep open-pit mine slopes with similar complex fault structures.
