基于D-InSAR的矿区沉降监测

Mine area subsidence monitoring based on D-InSAR

在简单介绍D-InSAR形变监测原理的基础上,分析了影响差分干涉结果精度的误差源,并给出了可能的消除办法。最后以陕北神木县大柳塔矿区为例,利用D-InSAR技术获取了该矿区的地表沉降,结果表明,D-InSAR技术可以有效地提供矿区沉降的最新信息,用于指导矿区生产和整体规划。

This paper gave a brief introduction of D-InSAR deformation monitoring principles and analysed the error sources which impact on the accuracy of the differential interference.This paper also gave the possible ways to eliminate the error sources.Finally this paper took the North Shaanxi province Shenmu Daliuta mine as an example and gained this mining area surface subsidence using the D-InSAR technology.The result had proved that D-InSAR technology could effectively provide the latest information of mining area subsidence and guide the production and the overall mining area planning.
