Abstract
To improve the measurement accuracy and efficiency of the stripping surface in open-pit mines,RTK technology and unmanned aerial vehicle oblique photogrammetry are studied and introduced.Taking a copper mine in Guizhou Province as an example,Leica GS18T receiver was used for control measurement,and high-resolution 3D modeling was achieved by using DJI M300RTK drone equipped with Zenith P1 camera.Adopting a multi-source data fusion strategy,combined with Leica Infinity software to process RTK ground control point coordinates and drone image data,an accurate 3D terrain model is generated,and a dynamic reserve calculation model is constructed to optimize resource reserve estimation.The results showed that this method shortened the single aerial coverage time to 45 minutes,improved measurement efficiency by about 100%compared to manual measurement,achieved a 3D modeling resolution of 1.5cm per pixel,reduced resource reserve estimation error by 67.3%,increased recovery rate by 2.2%,and optimized stripping ratio by 14.3%.This study provides a reliable technical path for fine management and digital transformation of mines.关键词
