%X Baiyun obo iron mine  is the  main raw material site of Baogang group, and is  famous for rare earth in the world. Slope monitoring is crucial to the production and safety of the mine. In this paper we present the microseismic monitoring system in the east mine of Baiyun Obo. Through laying out detectors and installing main and branch stations  as well as wireless devices, we carry out slope microseismic monitoring in regions of A, B and D on   different platforms. Furthermore,we collect and analyze the  monitoring data by using the system, accurately locating within the interior slope. In association with 3D displaying software, we directly obtain the locations and released energies of fracturing points of rock mass, realizing real-time monitoring in quarry slope. The results show that  at  present, region B and adjacent areas between region D and region C are  dangerous areas, for microseismic events of these areas are more than those of other areas. We should take special measures to prevent accidents in these areas. Finally, the system can be taken as reference for safety operation and slope treatment.
