Analysis and application of surface displacement monitoring technology of stope slope in open pit mine

The landslide risk of open-pit mine slope is a major hidden danger in mine production, and the monitoring of its surface displacement is a key preventive measure for the hidden danger of landslide. This paper introduces several main surface displacement monitoring technologies currently applied, analyzes the performance parameters and applicable conditions of several surface displacement monitoring technologies, and puts forward some suggestions for use, which provides a useful reference for the scientific and rational design of slope monitoring scheme.
