矿区地表形变是矿业开发过程中不可忽视的重要问题,其影响范围广泛,可能引发地质灾害、影响基础设施安全以及生态环境。其高精度、高时空分辨率特性,为矿区地表形变的精细化监测提供了重要手段。本文以山西矿区为研究对象,基于时序InSAR技术开展矿区地表形变精细化监测研究。首先,从数据采集与预处理入手,详细阐述SAR影像获取、轨道精校正、干涉图生成及噪声抑制等关键步骤;其次,依托时间序列InSAR解算模型,提取矿区地表形变的时间序列信息,分析形变特征及影响因素;最后,结合地质背景、矿区开采活动及水文条件等因素,探讨矿区形变的时空分布规律及其成因机理。研究结果表明,时间序列InSAR技术能够高效识别矿区地表细微形变,监测精度高,可为矿区地质灾害防控及矿山安全生产提供科学依据。
Mine surface deformation is a critical issue in mining development that cannot be overlooked.Its scope is potentially geological disasters,affect infrastructure safety,and damage the ecological environment.Time series InSAR(Interferometric Synthetic Aperture Radar)technology,relying on its characteristics of high precision and high spatiotemporal resolution,provides an essential method for refined monitoring of mine surface deformation.This paper takes the Shanxi mining area as the research object and conducts a study on refined monitoring of mine surface deformation based on time series InSAR technology.First,starting from data acquisition and preprocessing,it elaborates on key steps such as SAR image acquisition,orbit fine correction,interferogram generation,and noise suppression.Second,relying on the time series InSAR solution model,it extracts time series information of mine surface deformation and analyzed its characteristics and influencing factors.Finally,combined with factors such as geological background,mining activities,and hydrological conditions,we explores the spatiotemporal distribution laws and genetic mechanisms of mining area deformation.The results demonstrate that time series InSAR technology can efficiently identify subtle surface deformations in mining areas with high monitoring accuracy.
