• 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.
• Real-Time Estimation of Elemental Carbon Emitted from a Diesel Engine
  8/1/2007 - Peer reviewed journal articles
  This paper describes a simple, inexpensive, dependable, and field portable method for estimating the mass concentration of elemental carbon exiting the tailpipe of a diesel engine using a direct reading photometer in underground mines.
• Comparing Measurements of Carbon in Diesel Exhaust Aerosols Using the Aethalometer, NIOSH Method 5040, and SMPS
  4/1/2007 - Peer reviewed journal articles
  The objective of this paper is to compare the results among (1) a NIOSH published standard to determine the mass of EC and OC on filter samples, (2) the aethalometer, which uses light extinction to measure "black carbon" or BC, and (3) measuring particl...
• Characterization of Nanometer and Ultrafine Diesel Aerosols in the Underground Mining Environment
  4/1/2007 - Conference papers
  This paper identifies and characterizes nanometer and ultrafine aerosols emitted by diesel engines in the underground environment and evaluates the effects of selected contemporary control technologies.
• Instrumentation for Diesel Particulate Matter Emissions Research
  6/1/2006 - Conference papers
  The results of a series of tests in an underground mine were used to evaluate several measurement methods that are currently used to characterize particulate matter emitted by diesel-powered equipment. This paper presents an overview of these techniques...
• An Integrated Approach for Managing Diesel Emission Controls for Underground Metal Mines
  6/1/2006 - Conference papers
  Recent NIOSH experience suggests that more attention may be needed in managing the issues associated with diesel emissions and their control.
• DEEP Project on Evaluation of Diesel Particulate Filters at Inco's Stobie Mine
  6/1/2006 - Conference papers
  The objective of the Diesel Emissions Evaluation Program (DEEP)-sponsored project at Inco Ltd.'s Stobie Mine was to conduct a long-term field evaluation of diesel particulate filter (DPF) systems available to the underground mining industry. Some of the...
• Differential Pressure as a Measure of Particulate Matter Emissions from Diesel Engines
  4/1/2005 - Peer reviewed journal articles
  A diesel particulate matter analyzer capable of direct, real-time measurement of engine exhaust particulate is necessary to effectively institute source control technology currently being used on diesel equipment and to ensure that the control measures ...
• Real-time Neural Network Application to Mine Fire - Nuisance Emissions Discrimination
  5/1/2004 - Conference papers
  Discusses implementation of a real-time neural network which can discriminate mine fires from nuisance diesel emissions as part of an atmospheric mine monitoring system in NIOSH's Safety Research Coal Mine.
• A Computer Software Program that Estimates Air Quantity Requirements in Large Opening Stone Mines
  5/1/2004 - Conference papers
  Describes a computer program developed by NIOSH for estimating the air quantity needed to dilute diesel particulate matter in underground large opening mines.
