2026-10-14 Multi-track Sentinel-1 time-series InSAR surface deformation dataset (2021–2024) of the Tunbao Coal Mine, Changji, Xinjiang, China, and code for the geologically constrained Gaussian mixture model doi:10.57760/sciencedb.0143h en This dataset contains multi-track time-series InSAR surface deformation observations over the Tunbao Coal Mine, Changji, Xinjiang, China, derived from ascending Sentinel-1 imagery (Tracks 114 and 41), spanning January 2021 to May 2024 (approximately 100 epochs). All files are stored in Shapefile format under EPSG:4516 (CGCS2000 / 3-degree Gauss-Kruger projection), with deformation in millimeters (negative LOS values The dataset comprises six vector files: (1) 剩余点.shp - 20,185 Track-114 LOS cumulative deformation points outside the decoherence zone (fields include TBCJLJ114 cumulative LOS deformation, VEL deformation rate, COHERENCE, and per-epoch time series D20210109-D20240505); (2) 覆盖空白区范围.shp - boundary of the decoherence void to be infilled;(3) 覆盖区内点.shp - 1,428 Track-114 validation points inside the decoherence zone; (4) 空白区域.shp - fine boundary of the decoherence zone; (5) 屯宝煤矿114轨道完整沉降数据.shp - complete Track-114 settlement field; (6) 屯宝预处理范围内点.shp - Track-41 independent validation data (field TBCJLJ41). The dataset supports research3D deformation decomposition of mining-induced subsidence, validation of decoherence-zone infilling methods, and benchmarking of physics-based versus statistical models; it has been used in comparative experiments of the Geologically Constrained Gaussian Model (GCGM) against OK, SVR, SGM, IDW and PIM.
