Abstract:A management and emergency rescue system for tailings dam with centerline embankment based on 3D scanner is put forward in this paper. With 3D scanner as the measuring device, refined management on tailings classification and embankment process, and integrated management on emergency command and rescue can be realized. The system can enhance the safety of tailings dam, reduce cost of tailings classification and embankment, and serve as strong support to tailings dam emergence rescue, risk elimination and reinforcement, etc.
