AB  - The alpine region of the Qinghai-Tibet Plateau is a significant reserve of mineral resources in China. Intensive excavation and extensive tailings accumulation in the Muli mining area have severely disrupted the original topography, geomorphology, and geological conditions, seriously impacting the permafrost within the alpine mining area. This study integrates Landsat imagery, in-situ ground temperature measurements, and borehole logging data, utilizing the Google Earth Engine (GEE) platform and ArcGIS software. Employing methods such as Random Forest and the Stefan equation, we generated high-precision atlases of active layer thickness, thermal stability, and ice content at a spatial resolution of 30 meters for the alpine mining area. These datasets provide a robust foundation for research on permafrost distribution and thermal stability in alpine mining regions.
