Precise Monitoring and Damage Assessment of Surface Deformation in Industrial Site Mining by SBAS: Niuerzhuang Mine in Fengfeng Mining Area, Handan City
In order to achieve precise monitoring of surface deformation at industrial mining sites and to assess damage to buildings and structures, a method integrating PS-InSAR-based ground control point selection with SBAS-InSAR processing was proposed. Using 21 Sentinel-1A orbit-updated images from April 30, 2024 to February 12, 2025, combined with leveling measurement data, the inversion results of deformation were verified and their accuracy was evaluated. Meanwhile, the deformation indicators of key facilities were systematically extracted to assess the damage level of buildings (structures). The results show that the InSAR-derived measurements are in good agreement with the leveling data, with the mean absolute error and root mean square error being 4.1 mm and 5.1 mm, respectively. The spatiotemporal evolution of surface deformation in the study area is highly consistent with the mining activities of the 56903 working face, with a maximum subsidence rate of -172.9 mm/a. Since August 2024, the subsidence area has continuously expanded westward, showing obvious characteristics of uneven subsidence. The cumulative subsidence values of the main shaft and auxiliary shaft are 109.2 mm and 115.9 mm, respectively. Tilting deformation is identified in several buildings within the industrial site, and the damage grade is determined to be Grade I, whereas only limited additional tilting deformation is observed in ancillary facilities such as the hoist and ventilator. It is concluded that the proposed method can provide a technical reference for deformation monitoring and damage assessment of industrial sites in resource-depleted mines.

InSAR技术经过长时间发展,使得PS-InSAR、SBAS-InSAR和DS-InSAR等多种时序监测方法得以广泛应用[16]。为提升非均匀沉降区域的监测可信度,采用PS-InSAR优选地面控制点(ground control point,GCP)并与传统SBAS-InSAR联合处理。该方法的核心在于利用PS-InSAR对高相干点(如建筑物、井筒等)的识别能力,筛选出形变稳定区域作为GCP,以校正SBAS-InSAR解算中的轨道误差和大气延迟,从而提高形变反演的精度与可靠性。
差分干涉图有m幅,根据式(2)就可以得到相应的方程组,可利用最小二乘法求解待求差分干涉相位转化为相邻时相位变化的平均速率,最后对各时间段速率进行奇异值分解(singular value decomposition,SVD),获取视线方向(line of sight,LOS)平均相位速率的最小范数解,再进一步求解出各时相累积地表形变量[22]。
