ABSTRACT
The ability to observe and record imagery from a low height and across multiple electromagnetic spectrum bands enables both in-field inspection and detailed off-site analysis of terrain conditions in various aspects. This paper provides a brief overview of remote sensing methods used for the identification and assessment of hazards on mining waste disposal sites. Based on the authors’ own experience, the study presents data acquisition techniques employing remote sensing (including thermal imaging and LiDAR) and low-altitude photogrammetry, used either as standalone tools or as complementary approaches for early threat detection and technical condition assessment of post-mining sites. Selected case studies from the Upper Silesian Coal Basin are presented, including results of thermal condition assessments, terrain morphology measurements, slope stability analyses, and assessment of slope degradation due to water erosion.
