• Applications of the Point Estimation Method for Stochastic Rock Slope Engineering
  6/1/2004 - Conference papers
  The point estimation method for the probability of sliding is efficient and expedites slope stability simulation routines in NIOSH software to stochastically describe rock slope behavior and assist engineers in catch bench design for large slopes.
• Analysis of Bench Crest Performance at the Yellowstone Mine: A Case Study
  5/1/2004 - Conference papers
  A case study is presented that relates statistical descriptions of joint sets to the distribution of local wedge failures along the crest of a catch bench at the Yellowstone Talc Mine.
• Assessing and Monitoring Open Pit Mine Highwalls
  8/1/2001 - Conference papers
  This paper introduces warning signs of slope instability so operators are better able to recognize hazards. The most common slope monitoring equipment and practical methods of installation are discussed as well as the limitations of these systems.
• Applications of Ground-Based Radar to Mine Slope Monitoring
  5/1/2004 - Conference papers
  Several remote sensing technologies are being evaluated as tools to assess slope stability and monitor slopes for hazards. An interferometric radar device capable of detecting very small displacements on slopes has been assembled and tested.
• Evaluating Techniques for Monitoring Rock Falls and Slope Stability
  8/1/2002 - Conference papers
  Several remote-sensing technologies are being evaluated as tools to monitor slopes for hazards and to assess slope stability.
• Detecting Problems With Mine Slope Stability
  8/1/2002 - Conference papers
  Slope stability accidents are a leading cause of fatalities at U.S. surface mines. NIOSH is conducting research to reduce these fatalities. This paper presents some of the research and potential new technologies for slope monitoring and design.
• Shear Strength Evaluation of Clay-Rock Mixtures
  1/1/2000 - Conference papers
  This study reviewed 31 technical papers that analyze shear strengths for clay and sands containing rock particles. Results show that shear strength gradually increases with increasing percentages of floating particles in unsaturated clays.
• 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.
