A method for extracting geological information and stability assessment in goaf areas based on GIS and remote sensing technology

Insufficient extraction accuracy of geological information in goaf areas and low reliability of stability assessment are prominent problems in the current field of mineral resource development and geological security. To address the above challenges, this paper proposes a method for extracting geological information and assessing stability in goaf areas that integrates GIS and remote sensing technologies. The article first extracts the complete geological information of the goaf from three aspects: remote sensing data preprocessing, boundary division of the goaf, and extraction of geological elements. On this basis, the fuzzy comprehensive evaluation method is adopted to assess the stability of the goaf, aiming to provide a reliable basis for the governance and safety protection of the goaf.
