摘要
针对传统的监测方法都是基于点位监测,耗时耗力且难以大面积监测,本文以唐山某矿1326工作面为研究区域,利用二轨法D-InSAR的方法,采用两景Sentine1-1A数据对该工作面进行监测与分析,将所求取的监测结果分别与水准测量数据、利用开采深陷预计方法所预计出的该工作面以及受到开采影响的周边建筑物的下沉值进行对比验证。实验结果表明,D-InSAR监测值与开采沉陷预计的值结果较为一致,能够较为精确有效地监测矿区地表形变以及开采范围内的建筑物沉降。
In view of the traditional monitoring methods are based on the monitoring of point,time-consuming and difficult to monitor large area,papers in Tangshan mine 1326 working face as the study area,using 2 D-InSAR track method,the scene Sentine1-1A data monitoring and analysis of the working face,the monitoring results and the leveling data respectively,using the method of fusion probability integral method of mining in deep is expected to expect out of the influence of the opening to the working face and surrounding buildings subsidence value comparisons.The experimental results show that D-InSAR can accurately and effectively monitor surface deformation and settlement of buildings within mining area.
