Abstract: Aiming at environmental geological disasters like surface deformation caused by large-scale coal mining, this paper reviews the current research status of InSAR technology in coal mine surface deformation monitoring. The main issues with current InSAR technology include: severe phase decorrelation affects monitoring results; limited methods exist for accuracy verification; the accuracy of three-dimensional surface deformation monitoring in mining areas is restricted; and data analysis is insufficient. To address these issues, the paper proposes: ① Use SAR satellites with long wavelengths and short temporal baselines to reduce decorrelation. ② Strengthen DS-InSAR research for more precise monitoring. ③ Integrate multi-source remote sensing data to enhance accuracy. ④ Combine InSAR data with AI to support green and sustainable development in coal mines.
