• Use of Pressure Swing Adsorption Technology to Inert Sealed Mine Areas with Nitrogen
  2/1/2009 - Conference papers
  This paper describes the effort to create a reliable in-mine mobile plant for extracting nitrogen gas from the mine atmosphere. The gas produced by this novel technology can be used to create an inert environment in sealed mine areas.
• Behavior of Nitrogen Oxides in the Product Gases from Explosive Detonations
  1/1/2006 - Conference papers
  Toxic fumes generated by explosives have been a concern for blasters, explosive manufacturers, and mining companies. In this study, 10 lb. charges of confined blasting agent were detonated in a closed chamber, and then detonation gases were analyzed.
• The Effects of Passive Diesel Particulate Filters on Diesel Particulate Matter Concentrations in Two Underground Metal/Nonmetal Mines
  6/1/2010 - Conference papers
  In this study, NIOSH measured the atmospheric concentrations of DPM and gases in two mines in order to evaluate the effects of various control strategies on the atmospheric DPM concentrations.
• Advances in Grid-Based Numerical Modeling Techniques for Improving Gas Management in Coal Mines
  6/1/2008 - Conference papers
  This paper summarizes the modeling efforts conducted by NIOSH in the U.S. and CSIRO in Australia to address various gas management issues encountered in longwall mines using the application of computational fluid dynamics (CFD) and numerical reservoir m...
• Effects of Sintered Metal Diesel Particulate Filter System on Diesel Aerosols and Nitric Oxides in Mine Air
  6/1/2008 - Conference papers
  This NIOSH study was conducted to establish the effects of a diesel particulate filter (DPF) system with sintered metal substrate on the concentrations and size distributions of nano and ultrafine aerosols and concentrations of nitric oxides in undergro...
• Examination of Diesel Aftertreatment Systems at NIOSH Lake Lynn Laboratory
  10/1/2007 - Conference papers
  A paper describing tests conducted in the NIOSH Diesel Laboratory at the Lake Lynn Laboratory experimental mine, a facility developed to allow evaluation of control technologies directly in an underground environment.
• Effect of Coal Type and Oxyfuel Combustion Parameters on Pulverised Fuel Ignition
  8/1/2007 - Conference papers
  This paper describes ignition tests on pulverised coal suspensions using a suite of coals of different rank and from different countries of origin and over a range of oxygen and coal concentrations of interest for oxyfuel combustion.
• Computational Fluid Dynamics Study on the Ventilation Flow Paths In Longwall Gobs
  6/1/2006 - Conference papers
  This paper focuses on the flow patterns within the gob under three different ventilation systems: one-entry and two-entry bleederless systems, as well as a three-entry bleeder system.
• Methods to Determine the Status of Mine Atmospheres - an Overview
  4/1/2006 - Conference papers, Peer reviewed journal articles
  This paper serves as an overview to remind and/or instruct readers about gas-sampling methodologies and gas analyses to assist in determining the status of underground atmospheres.
• Fugitive Carbon-Based Gases: Blasting Related or Not
  2/1/2004 - Conference papers
  This paper discusses elements of a stray gas investigation and the analyses necessary to identify the source of a stray gas.
