SLOPE STABILITY RADAR

It is generally true that rock mass movements and deformations will occur through regular open pit mining operations potentially leading to slope instability or wall failure. Slope stability radar is a relatively new technology and is improving the way mines manage and minimize the risks associated with slope instability, enabling the appropriate precautionary measures to be taken. This technology meets the requirements that a monitoring system should have regarding precision, area coverage and failure mode detection. It is reliable in a variety of conditions, operates in a safe mode not requiring personnel to work on or near an instability, and does not obstruct mining operations. Data is easily interpreted and transmitted continuously in real time enabling engineers to make more informed decisions about production and slope design. The precision necessary is achieved through signal processing by differential interferometry using associated sofware. Differential interferometry uses the phase information contained in each return pulse and compares it to a previous returning pulse. Measurements of deformation and ground movements can then be deciphered through the differences in the phas
