Monitoring prism installation 2

Monitoring Prism are devices used by the geotechnical team at the mine to monitor the high wall or any unstable or detaching rocks on a high wall. The devices are drilled on a rock held by a mounting plate and then we number and paint around the prisms so that the geotech team can know which prism is active or needs fixing. We mostly use rope access techniques to install these devices but if the height allows we use lifting equipment.
