浅谈基于InSAR的南票煤矿开采沉陷区沉降量外业检核

Study on Settlement Amount External Check of Land Subsidence in Nanpiao Coal Mining Based on InSAR

经过时间序列InSAR技术处理后,得到监测时间段内南票区的地面形变平均速率、累计形变量、时间序列形变量,确定沉降区域。本文通过南票煤矿开采沉陷区基岩点、基本水准点、监测点布设以及这些点测量工作,提出山区采用水准测量和GPS测量联合方法,实现沉陷区沉降量核查。

After the processing of time series InSAR（ Interferometric Synthetic Aperture Radar） technique,land subsidence average rate,cumulative deformation and time series deformation of Nanpiao area in the course of monitoring are got,meanwhile,the subsidence area is detected. In this paper,by means of Nanpiao coal mining subsidence bedrock point,basic bench mark and the layout of monitoring points as well as measurement work,a combination of level measurement and GPS measurement is presented and adopted in the mountain area,contributing to settlement amount check in subsidence area.
