• Description:
  3DTOM is A DOS-compatible computer program developed by the U.S. Bureau of Mines of three-dimensional tomographic imaging of the subsurface at mine sites. The program uses the simultaneous iterative reconstruction technique (SIRT) to invert travel-time data and produce maps of wave velocity, or to invert amplitude data and generate maps of wave attenuation coefficients. 3DTOM permits the use of hard constraints, or soft constraints based on fuzzy logic, to allow for uncertainty in the constraints. Reliable subsurface images are useful in many different mine-related problems, including void detection, fracture detection, fluid monitoring, and qualitative stress evaluation.
