• Scaled Cloud Model for Released Toxic Fumes
  1/1/2001 - Conference papers
  Recognizing the dynamic nature and possible range of toxic concentrations in the impending fume cloud prior to undertaking explosive blasting can reduce potential hazards and mitigate related incidents. The scaled cloud model was formulated to predict t...
• Evaluation of New Methods and Facilities to Test Explosion-Resistant Seals
  1/1/2001 - Conference papers
  This paper provides a brief overview of the ongoing study to evaluate the use of these chambers for pressure loading of full-scale seal designs using compressed air, water, or internal gas explosions.
• Research by NIOSH for Controlling Respirable Dust and Methane Gas on Continuous Miner Faces
  1/1/2001 - Conference papers
  The importance of controlling respirable dust and methane gas levels in underground coal mining cannot be underestimated. While respirable dust can significantly affect the occupational health of underground coal miner, methane gas accumulations pose s...
• Reducing Worker Exposure To Dust Generated During Longwall Mining
  1/1/2001 - Conference papers
  Longwall mining equipment has improved dramatically over the last 15 years. Although significant gains in longwall dust control have been made, they have been challenged by significant increases in coal extraction rates resulting in more dust being gene...
• Random Motion Capture Model for Studying Events Between a Machine and its Operator
  1/1/2001 - Conference papers
  This paper presents a technique for representing and analyzing random motions and hazardous events in a computer simulated three-dimensional workplace, providing machine designers and safety analysts with a new technique to evaluate ways to reduce opera...
• Size Distribution and Deposition in Human Respiratory Tract: Particle Mass and Number
  1/1/2001 - Conference papers
  Objectives: To determine the regional deposition of particulate matter in human lungs for a variety of steady-state engine operating conditions, fuel formulations and combinations of after treatment devices, and to characterize the size, distribution an...
• Experimental Investigation of On-Line Methods for Incipient Fault Detection
  10/1/2000 - Conference papers

• Evaluation of Two-Phase Spray System for Airborne Dust Control in a Longwall Gallery
  9/1/2000 - Conference papers
  The increased effectiveness of a two-phase spray system (TPSS) over a single-phase system (SPSS) for dust suppression is reported in several laboratory studies.
• NIOSH Research for Controlling Respirable Dust and Methane Gas on Continuous Miner Faces
  9/1/2000 - Conference papers
  The importance of controlling respirable dust and methane gas levels in underground coal mining cannot be underestimated. This paper reviews practical applications of water sprays and dust scrubbers to control respirable dust and methane gas on continu...
• Coal Mine Seismicity and Bumps: Historical Case Studies and Current Field Activity
  8/1/2000 - Conference papers
  Research on techniques that will reduce the hazards in the mining workplace associated with coal bumps.
