... ABSTRACT The rapid development of unmanned aerial vehicle (UAV) technology has enabled numerous open pit and underground mining companies to leverage this tool for slope stability assessment and the construction of geotechnical models. The use of aerophotogrammetry techniques with UAVs enables...

... Abstract: Application of downhole geophysical logging techniques, specifically Acoustic Televiewer (ATV) and sonic logging, is used to significantly enhance pit slope stability assessment for proposed or expanding open pit and quarry mining operations. Acquisition of discontinuity...

INTRODUCTION Excavations are central to both mining and many civil engineering projects. For both economic and safety reasons reinforcement forms...

... of minimising the induced stability. 2. COLLECTION OF FIELD DATA Data representative of the discontinuities present in the host rock mass must be collected to enable stability assessments to be made and an optimum design to be established. This is normally accomplished at an early stage in the site...

... to assess the nature of unstability. The shear strength of natural discontinuities was obtained by direct shear testing in the laboratory. The paper presents the application of this approach to the stability assessment of two roadstone quarries in Limestone and Basalt respectively. 2 RESEARCH APPROACH...
