• Lightning Propagation Through the Earth and its Potential for Methane Ignitions in Abandoned Areas of Underground Coal Mines
  10/1/2002 - Conference papers
  This paper addresses the question, 'Can lightning cause potential differences capable of igniting methane-and-air mixtures at overburden depths at which underground coal mining occurs?'
• Mine Emergency Response Command Center Training Using Computer Simulation
  8/1/2002 - Conference papers
  This paper discusses the Mine Emergency Response Interactive Training Simulation (MERITS), a computerized simulation for providing mine emergency command center training.
• Drill Monitor With Strata Strength Classification in Near-Real Time
  7/1/2002 - Reports of Investigations
  The process of drilling and bolting the roof is currently one of the most dangerous jobs in underground mining, resulting in about 1,000 accidents with injuries each year in the United States. Researchers from the Spokane Research Laboratory of the Nat...
• Technology News 496 - NIOSH Releases New Computer-Based Training Exercise Called MERITS
  6/1/2002 - Technology News
  MERITS simulates underground and surface events related to the disaster. It exposes the user to events that typically occur during a mine emergency, such as lack of information and miscommunication. It also presents trainees with issues that must be add...
• Motion Editing and Reuse Techniques and Their Role in Studying Events Between a Machine and its Operator
  4/1/2002 - Conference papers
  The first part of this paper is a review of several new techniques developed to facilitate the manipulation, noise reduction, storage and reuse of captured data, which have a potential to reduce the overall cost of motion simulation and improve its real...
• Verification and Validation of Roof Bolter Simulation Models for Studying Events Between a Machine and its Operator
  6/1/2001 - Conference papers
  This paper presents the results of a study to verify and validate a computer model that represents and analyzes motions and hazardous events in a simulated three-dimensional workplace. The purpose of the computer model is to support research that is in...
• Computer Modeling of Catch Benches to Mitigate Rockfall Hazards in Open Pit Mines
  7/1/2000 - Conference papers
  In a computer analysis of bench stability, bench-scale plane shears and tetrahedral wedges are simulated and stochastically analyzed to estimate the probability of retaining specified catch-bench widths.
• 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.
• Use of Strain-Gauged Rock Bolts to Measure Rock Mass Strain During Drift Development
  6/1/1999 - Conference papers
