• Simplified Hyperspectral Imaging for Improved Geologic Mapping of Mine Slopes
  5/1/2003 - Book chapters
  A prototype portable hyperspectral imager was field tested at an open-pit mine as part of an investigation of remote sensing technologies for use in detecting and monitoring conditions in surface mines that could lead to catastrophic slope failure.
• An FMM-FFT Accelerated SIE Simulator for Analyzing EM Wave Propagation in Mine Environments Loaded with Conductors
  5/1/2018 - Peer reviewed journal articles
  An article presenting an FMM-FFT-SIE full-wave simulator used to characterize EM wave propagation in electrically large and loaded mine environments.
• Current Research on Slope Movement in Mines: Use of Hyperspectral Imagery
  1/1/2000 - Conference papers
  NIOSH is investigating remote sensing technologies to detect, monitor, and mitigate surface mine hazards that lead to slope failure. A field-portable spectro-polarimetric imager and a stationary interferometric radar device are promising options.
• A Feasibility Study for the Detection of Weak Electromagnetic Signal/ Bursts With Hard-Limited Arrays
  11/1/1981 - Contract reports
  A prototype detector using electromagnetic signals for finding trapped miners has previously been built and tested. The signals are generated from transmitters carried on the miner's belt and powered by his head lamp battery and the receiver is a human ...
