国产地基合成孔径雷达监测预警系统在紫金山金铜矿露天采场边坡位移监测的应用

紫金山金铜矿是福建紫金矿业集团股份有限公司下属的一个矿山基地，其露天采场将是全亚洲第一高露天矿山边坡。基于目前矿山采用的全站仪、GPS等监测技术，易受粉尘、降雨、光照、云雾等影响，无法实现大范围边坡区域实时、自动监测。而地基合成孔径雷达差分干涉测量技术则可以克服上述缺陷，该技术是滑坡监测技术未来的发展趋势，对于灾害预报及防治具有重要意义。介绍了国产地基合成孔径雷达边坡位移监测预警系统在紫金山金铜矿露采边坡的首次应用，验证了地基合成孔径雷达系统用于形变监测的可靠性、有效性及高精度等优势。

Application of domestic ground based synthetic aperture radar monitoring and warning system in slope displacement monitoring on open pit of Zijinshan gold/copper mine

The Zijinshan gold/copper mine belongs to Zijin Mining Group Co., Ltd., and its open pit will be the biggest open mine slope in Asia. An innovative technique for the remote assessment of small surface movement monitoring, based on differential interferometry and Ground-Based Synthetic Aperture Radar(GB-SAR), has been developed in recent years, which has some advantages comparing with other methods like GPS and full-station to cover large surface areas for two dimensional monitoring day and night under almost any weather condition. In this paper, the first application of domestic GB-SAR slope monitoring and warning system in Zijinshan Gold/Copper mine open pit was introduced . The advantages of applying GB-SAR on deformation monitoring, such as reliability, ef-fectiveness and high accuracy were validated.
