Study on the Information Fusion Technology in the Large-Scale Landslide Body Monitoring in Open Pit Mine

摘要

Monitoring the stability of the reinforced large scale Inndslide body Is one of the most important contents in the open-pit side slope project. To reveal the false appearance that the side slope had been In an accelerate defomation stage leading by the unsteady motion of the Inndslide body, the author designed the method of multi measurement, ud took the Kalman filter as the estimate means, using the centralized and distributed Information fusion technology, took the data coming from several sensors, and converted them to the sue coordinate system by the coordinate and unit alternation, then got the state vectors single-point optimal estimate. In the paper, the author took the B area 2# landslide body in the east deposit of Baiyunebo Iron Mine (BIM) as the study object, monitored anchoring force of the landslide body and the surface displacement, and analyzed the monitoring result with information fusion method. The study Indicated that the analysis result from the information fusion technology was able to get rid of the false Information effectively.
