Abstract: Discontinuity data of rock masses are critical for the characterization, design, and analysis of rock fabrics as related to small- and large-scale slope stability. They present the most common challenges in the design of open pit mines as adverse rock fabric orientations may impart instabilities that have the potential to cause losses of life, infrastructure, and decrease in productivity. Therefore, accurate and precise characterizations of discontinuities are a crucial step in successfully designing stable slopes. Terrestrial LiDAR scanning coupled with high resolution images can be used for virtual mapping of discontinuities. The benefits of implementing LiDAR as concerned with discontinuity mapping include ease of operation, improved safety, ability to collect data in inaccessible areas, short data acquisition time relative to manual data collection, and most importantly, pertinent rock mass data may be collected in much greater detail. A case study from an open pit mine was performed to evaluate if correlations exist among discontinuity properties collected using different methods including (1) traditional cell mapping, (2) optical and acoustic borehole imaging (OBI and ABI, respectively) with sampled core and, (3) high resolution LiDAR scanning. The advantages and disadvantages of these techniques are discussed and recommendations based on the results are presented in this study.
