Monitoring Underground Mine Displacement Using Photogrammetry and Laser Scanning
… of rock masses and their support systems in underground mine environments. Displacements underground are traditionally measured through point measurement devices, such as extensometers. These are generally restricted to measuring one dimension, may change behavior with installation, may …
