合成孔径雷达干涉测量(DInSAR)技术是监测动态地表沉陷的新方法，能够大范围地监测地表下沉盆地的动态演化过程，可以较好地反映各阶段的地表下沉形态。但是受到噪声等因素的影响，基于DInSAR数据计算的倾斜、水平变形等曲线规律性较差，与实际偏差较大，而倾斜、水平变形又是研究地表受护对象是否安全的重要指标。基于DInSAR监测数据，采用数值模拟方法，对澳大利亚West Cliff煤矿长壁工作面32开采动态地表移动变形进行分析研究。结果表明，数值模拟得到的下沉曲线与DInSAR实测数据比较吻合，相关系数可达95%以上，且数值模拟方法求算的地表倾斜、曲率和水平变形与理论形态一致。因此，进行矿区地表及其附属建（构）筑物受采动影响分析时，应以DInSAR实测数据为基础确定模型参数，结合数值模拟方法揭示地表动态其他移动变形值的分布规律。研究表明，该方法具有良好的适用性，可为类似的情况提供参考。

Differential interferometric synthetic aperture radar (DInSAR) technology is a new method to monitor the dynamic surface subsidence. It can monitor the large scope of dynamic deformation process of surface subsidence basin and better reflect the surface subsidence form in different stages. But under the influence of factors such as noise and other factors, the tilt and horizontal deformation curves regularity calculated by DInSAR data are poorer and the actual deviation is larger. The tilt and horizontal deformations are the important indices for the safety of surface objects protection. Numerical simulation method was used to study the dynamic deformation of LW32 of West Cliff colliery in Australia based on the DInSAR monitoring data. The result indicates that the subsidence curves of two methods fit well and the correlation coefficient is more than 95%. The other deformations calculated by numerical simulation results are close to the theory form. Therefore, considering the influence, the surface and its subsidiary structures and buildings due to mining, the numerical simulation method based on the DInSAR data can reveal the distribution rules of the surface dynamic deformation values and supply the shortcomings of DInSAR technology. The research shows that the method has good applicability and can provide reference for similar situation.
