This paper discusses the technique of applying terrestrial lidar (light detection and ranging) survey data to validate blast mitigation procedures. A controlled blasting exercise was required at Brusei, Switzerland to reduce risk on a dangerous rock slope. Three-dimensional (3D) point clouds derived from laser scanning were acquired before and after a controlled blasting exercise. These data were then used to assess the accuracy of blast volume estimations calculated during the planning of the blast. This study has concluded that blast volumes had been underestimated. Further discussion is provided that illustrates how terrestrial lidar scanning provides value to geological studies by effectively capturing high-resolution 3D survey data. The study also concludes that careful thought and planning must always be an essential part of the survey design and treatment of data during the analysis phase.
