基于D－InSAR方法求取深部开采地表移动参数研究

摘要

The features of deep mining are long range, long time and the preservation of the points are difficult have a long-time.At present, there are almost no regular observatory stations in China.In order to solve this issue, based on the research on the theory of D-InSAR and data processing methods, the different results of pictures were obtained.Through the comparison between different re-sults and field measurement, it can prove that the results of D-InSAR are right.After the exaction of the main section data, the prob-ability integral method parameters were also calculated based on the cooperation of the calculated method of parameters under the con-dition of observation point loss case.The results can provide guidance to the mining area.%深部开采有着地表沉陷时间长、范围大，地表测点难以长时间保存的特点，目前我国几乎没有深部开采的正规观测站。为解决这一问题，本文采用了D－InSAR技术获取了徐州矿区张小楼千米深部开采地表沉降数据，通过将监测结果与地表水准测量进行对比，证明了D－InSAR结果的正确性，并结合测点缺失情况下地表移动参数的求取方法，基于D－InSAR数据求取了千米深部开采地表移动参数。结果表明采用D－InSAR方法对深部开采地表移动的监测可以解决深部开采地表移动参数的求取问题。
