白云鄂博铁矿是包钢的主要原料基地,是举世闻名的稀土之乡,其采场边坡监测对矿山生产及安全而言极为重要。介绍了白云鄂博东矿的微震监测系统,通过各平台检波器的布置、主分站的安装、无线设备的安装,实现了对A,B,D区域的边坡微震监测。微震监测系统采集分析监测数据,能在边坡内部精确定位,并通过三维展示软件,直观地呈现岩体破裂点的位置、能量大小,实现采场边坡的实时监测。应用结果表明:目前监测时间内,边坡B,D区与C区相邻的范围较其它区域事件个数较多,微震事件较为活跃,为相对危险区域,应重点采取防止措施。微震监测系统实现了对采场边坡的实时监测,该系统对指导安全生产和边坡加固具有极其重要的意义。

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.
