Monitoring Prisms 64mm

Monitoring Prisms are critical in any mining application. Slope instability can be expected at any surface mining operation, but the unpredicted movement of ground endangers lives and destroys property. Unstable slopes are unsafe for miners who work on or beneath them, and large-scale failures have the potential to cause loss of life.

Diligent monitoring of structures and slopes for early warning signs are imperative for protecting life and equipment. As a recognised solution, prisms have been used for monitoring unstable slope zones or areas for many years, and aids in monitoring suspected/likely unstable slope zones or areas of interest.

Our waterproof Monitoring Prisms are certified and tested using laser interferometer and have been found to comply with the applicable National Standards and the manufacturer's QA Standard ISO9001. Equipment used during manufacture and inspection has traceable accuracy to the National Length Standard.
