Site characterization using drone based photogrammetry
An emerging topic in geotechnical site characterization is using drones for rock mass characterization through Structure from Motion (SfM) photogrammetry. This study highlights a series of surveys utilizing a DJI Mavic II drone performed between July and August 2022 at an abandoned quarry in Clear …

A New Tool for Rock Mass Discontinuity Mapping from Digital Images: VTtrace
… this task could minimize human exposure to rockfalls, rockbursts or instabilities and facilitate the use of new methods of data visualization such as virtual environments. This research was undertaken to develop VTtrace; a semi-automatic fracture mapping algorithm based on image processing …

Evaluation of strata conditions and performance of support systems of the Emerald Shaft Gold Mine in Gauteng Province of South Africa
… excavations causes disturbances in the rock mass, leading to geotechnical uncertainty and increased risk of fall of ground or backbreak. The incompetency of the rock mass, high tensile fractures, and concentration of horizontal virgin and mining-induced stresses pose significant threats …
