Abstract

In satellite image-based law enforcement for minerals, using unmanned aerial vehicles (UAVs) for investigation and aerial photography in mining areas with complex geographic conditions and unknown staffing situations, and photogrammetry for three-dimensional modeling of mining areas serves as an effective means to ensure the personal safety of field workers and improve work efficiency and accuracy. Lightweight UAVs are more applicable to satellite image-based law enforcement for highly mobile minerals due to their flexible take-off and landing conditions and high maneuverability while ensuring shooting clarity and modeling data requirements. Based on the UAV aerial survey results of several mining faces in Liaoning Province, this study demonstrates that satellite image-based law enforcement for minerals assisted by lightweight UAVs can significantly improve the efficiency and safety of fieldwork. Moreover, the modeling results provide data support for subsequent accurate survey and analysis and multi-temporal monitoring in mining areas.
