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。 Based on the actual situation of Changba Open-pit Mine, this paper established GPS slope displacement monitoring system, including the determination of monitoring points and monitoring range, the layout of monitoring network, monitoring methods and monitoring cycle. Finally, the monitoring results were briefly analyzed according to the site conditions. Practice shows that GPS monitoring can achieve the accuracy and requirements of mine slope deformation monitoring. The results show that the whole slope is safe, but there is a potential risk of instability in the northern slope, and the stability of the east slope is higher than that of the northern one However, the safety management of the slopes should still be strengthened so as to prevent some landslides.
