• The Effects of Disaster on Workers: A Study of Burnout in Investigators of Serious Accidents and Fatalities in the U.S. Mining Industry
  5/1/2000 - Conference papers
  Based on the anecdotal data, the authors suggest that specific training in working with grieving families and greater organizational support would be appropriate. In addition, utilizing local community mental health and/or pastoral services are suggested.
• Mine Fire Source Discrimination Using Fire Sensors and Neural Network Analysis
  4/1/2000 - Conference papers
  Report on the application of a neural-network program using mine sensor data to classify the type of fire.
• Determination of Physical Properties of Cable Bolts in Cement Grout Pull Tests Using Instrumented King Wires
  4/1/2000 - Conference papers
  Researchers are investigating the physical properties of cable bolts by replacing the conventional king wire with a modified king wire on which strain gauges have been installed.
• Creep Along Weak Planes in Roof and How It Affects Stability
  3/1/2000 - Conference papers
  A NIOSH study of the time-dependent response of rock stressed along weakness planes with the objective to improve mine safety by reducing the number of roof falls that cause injuries and fatalities to miners.
• Field Tests of Cable Bolts Using Instrumented King Wires
  3/1/2000 - Conference papers
  Instrumented cable bolts developed at the Spokane Research Laboratory of the National Institute for Occupational Safety and Health were used in conjunction with existing ground control to monitor rock mass loads at various field sites.
• Factors Affecting ANFO Fumes Production
  2/1/2000 - Conference papers
  Study of toxic fumes produced by the detonation of various ammonium nitrate/fuel oil (ANFO) mixtures and several cap-sensitive explosives.
• Implications of Recent NIOSH Tracer Gas Studies on Bleeder and Gob Gas Ventilation Design
  2/1/2000 - Conference papers
  A paper describing research at a Pittsburgh Coalbed longwall mine to evaluate and optimize bleeder ventilation and gob gas venthole longwall methane control systems.
• 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.
• A Review of Occupational Silica Exposures on Continuous Mining Operations
  1/1/2000 - Conference papers
  A Review of Occupational Silica Exposures on Continuous Mining Operations.
• A Simulation Approach Analyzing Random Motion Events Between a Machine and its Operator
  1/1/2000 - Conference papers
  An approach for representing and analyzing random motions and hazardous events in a simulated three-dimensional workplace, providing designers and analysts with a new technique for evaluating operator-machine interaction hazards in virtual environments.
