Research on slope monitoring technology of ultra-high altitude open-pit mine based on S-SAR slope radar
To study the radar monitoring technology of ultra-high altitude open-pit mine slope,the key monitoring area delineated by the high and steep slope of Xishan in the open-pit stope of Julong copper mine in Tibet was taken as the research object,and the synthetic aperture slope radar(S-SAR)monitoring data was analyzed.The results show that the radar monitoring data of ultra-high altitude open-pit mine slope is affected by many aspects,including topography,weather and climate,geological structure lithology,human interference and data processing technology.In addition,it is also found that the freezing period and thawing period of high-altitude open-pit mines are important factors affecting the stability of the slope,and the freezing causes the soil to expand and increase the internal pressure,while the thawing weakens the soil strength and aggravates the infiltration of frozen water.Therefore,by studying the slope displacement monitored by the slope radar in real time,the deforma-tion of the slope can be quickly discovered,and the deformation law of the slope can be effectively understood,so as to effectively improve the overall s afety of the mine.
