| 摘 要： | 本文采用小基线技术即SBAS-InSAR处理淮南市谢家集矿区的8景ALOS-PLASAR数据，时间跨度为2007年1月—2011年2月。首先利用SBAS-InSAR技术提取该矿区的时序形变速率，得到累计整体沉降趋势；然后针对公路、铁路、新旧矿区等重点沉降区域进行分析。由监测结果分析可知，十涧湖西路、堤坝整体处于下沉状态，西张铁路的西半段处于抬升状态，而东半段则下沉严重；东方矿井及新二矿区均处于不同程度的下降状态。

| Abstract: | The 8-scenario ALOS-PLASAR data of Xiejiaji mine in Huainan city is processed using the small baseline technology,SBAS-InSAR,from January 2007 to February 2011. Firstly,the SBAS-InSAR technology is used to extract the time-series deformation rate of the mining area to obtain the cumulative overall settlement trend. Then it analyzes the key settlement areas such as roads,railways,new and old mining areas,etc. From the analysis of the monitoring results,it can be seen that the Shijian Lake west road and the dam are in the lower overall. In the sinking state,the western half of the Xizhang railway is in an uplifted state,while the eastern half is sinking severely. The Dongfang mine and the Xiner mining area are in different degrees of decline. |
