Abstract: In order to improve the recovery rate of Anjialing Openpit Mine,it is planned to organize mining operations at the northern end of the mine.In order to strengthen the monitoring work of slope during the mining of steep slope,to ensure the stability of slope and the safety of personnel,the radar monitoring system of synthetic aperture interferometer slope is introduced in anjialing openpit mine.By studying the principle,technical characteristics and system structure of synthetic aperture interferometric slope radar,the monitoring data of slope during steep side mining was analyzed,and the deformation area of slope was discovered in time.The results show that the radar can realize the large range and high precision realtime automatic monitoring of the slope of the openpit mine and meet the requirements of the slope monitoring of the openpit mine.
