Abstract: There are a large number of natural or manmade slopes in openpit mines,all of which have different degrees of potential landslide hazards.In order to ensure the safe of the slopes,it is necessary to conduct safety monitoring.In view of the shortcomings of traditional measurement methods,pplies 3d laser scanning technology to the slope deformation monitoring,studies the theoretical technology and data application analysis of the implementation of monitoring,realizes the effective deformation monitoring of the mine slope,and obtains the ideal monitoring results.

Key words: 3D laser scanning technology, Open stope, Slope, Deformation monitoring
