The application of a digital photogrammetry system to structural mapping at a large open pit mine

Photographic surveys of the Paul's Peak and Baseline B open pit mines of the Quebec Cartier Mining Company were performed. Six pairs of glass photoplates were scanned and stored as digital images. Commercial digital photogrammetry software was used to create a stereoscopic model for each set of images. The three-dimensional coordinates of distinct features were measured. A total of approximately 6000 measurements was made. Two drawings were prepared for each model. The first drawing consists of features with model coordinates, the second drawing consists of features with mine coordinates.;The software that was developed as part of this thesis enables the user to create contour lines for selected points, calculate the strike and dip between pairs of contours and create input files for use with commercially available stereonet plotting software.;The software was applied to a structural analysis of the Paul's Peak and Baseline B pits.;Conclusions and recommendations are made to improve the method and accuracy of the photogrammetry system for future studies.
