Study on deformation characteristics of high and steep slopes under rainfall-blasting coupling based on S-SAR technology
For the high and steep slope of the north gang of Suhaitu open pit mine,the mechanism of rainfall-blasting vibration coupling on slope stability was analyzed,and the slope deformation data under rainfall-blasting vibration were monitored and analyzed in real time by using S-SAR slope radar monitoring technology.The results show that in the strong rainfall season,the slope stability is poor.When rainfall-blasting vibration at the same time,the surface deformation of the slope shows a fluctuating upward trend,compared with the non-rainy season period,rainfall-blasting coupling has a greater impact on the stability of the slope,which is the focus of the landslide disaster time period.The results of the study can provide a certain reference for the study of the stability of high and steep slopes under rainfall-blasting coupling and further promote the application of slope radar monitor-ing technology in open-pit mine engineering.
