• Description:
  Photogrammetric methods are advancing rapidly and show considerable promise as a ground control research and monitoring tool. The ability to quickly capture three-dimensional geometry in field and laboratory settings is a significant advancement in deformation monitoring. Photogrammetry is being applied in both settings as part of the NIOSH ground control research program. This paper describes three applications of photogrammetry for use in ground control monitoring. First, photogrammetry was used to measure complete patterns of ramp rib and back deformation caused by creep and mining-induced seismicity. The results of this application are being used in a mine visualization project. Second, relative displacements across seismically active faults were measured photogrammetrically. Case studies are provided that illustrate how photogrammetry may be used to supplement crackmeter monitoring systems. Third, photogrammetry was used in laboratory tests to delineate the relationship between shotcrete and mesh intra-bolt bulge deformation and residual support strength. Results of this application were applied to field situations. [Description provided by NIOSH]
