GB-InSAR集成GIS的露天煤矿边坡变形监测

对露天矿边坡进行实时、精确测量可为边坡提供可靠的预警和治理信息,直接关系到露天矿的生产连续性和效益。地基SAR干涉测量技术(GB-InSAR)是最近10年发展起来的一种相对较新的变形监测技术,具有全天候、全天时的观测特点。而国内针对露天矿边坡变形监测大多处于试验阶段,缺乏长时间连续观测的能力,本文详细地阐述了GB-InSAR的基本原理,并将GBInSAR得到的变形数据与GIS有机地连接起来,利用GIS强大的空间显示、分析能力,高效、实时、直观地展示变形信息,为露天矿生产提供了有力的决策支持。

Slope Deformation Monitoring of Open Pit Coal Mine by GIS Integrated GB-InSAR

The real-time and accurate monitoring for open pit coal mine slope can provide reliable information for slope stability and early warning,which is directly related to the economic benefit and sustained production.The ground-based InSAR (GB-InSAR),a relatively new technology for deformation monitoring,has been developed in the last ten years,which has the characteristics of all-weather and all day.However,most of the open pit slope deformation monitoring in China are in the experimental stage,which lacks the ability of continuous observation for a long time.In this paper,the basic principle of GB-InSAR is described in detail and the deformation data obtained by GB-InSAR is organically connected with GIS.Deformation information is efficiently,real-time and intuitively displayed by using of GIS powerful spatial analysis and display ability,providing powerful decision support for open-pit mine production.
