GPS在厂坝露天矿边坡位移监测中的应用

本文结合厂坝露天矿实际,建立了GPS边坡位移监测系统,包括监测点和监测范围的确定、监测网的布设、监测方式与监测周期等等,最后结合现场情况对监测结果进行简要分析。实践表明,GPS监测能够达到矿山边坡变形监测的精度和要求,结果显示边坡整体是安全的,但北帮边坡局部潜在着失稳风险,东帮边坡稳定性比北帮的要高,但仍要加强边坡的安全管理,防止局部滑塌。

Application of GPS in Chengba Open Pit Slop Displacement Observation

Based on the condition of Changba open bit mine,GPS slope displacement observation system is set up. It includes fixing monitoring mark and area, laying out monitoring network, determining the methods and periods of observation etc. Finally, the monitoring results should be briefly analyzed based on the on-site conditions.It has proved that GPS can satisfy the accuracy and the requirements of mine deformation monitoring.The results show that the slope is safe,but the failure risk exists in some parts of the northern side.However,the eastern slope is more stable,safety control should be strengthened to prevent slides.
