• Effectiveness of Selected Diesel Particulate Matter Control Technologies for Underground Mining Applications: Isolated Zone Study, 2004
  8/1/2006 - Reports of Investigations
  This study evaluated the effectiveness of the state-of-the-art technologies for controlling DPM and gaseous emissions from underground diesel-powered mining equipment using the isolated zone approach.
• 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.
• A Compact, Wearable, Personal Monitor for Real-Time Detection of Nitrogen Dioxide in Mines
  7/18/2016 - Contracts and cooperative agreements
  A contract to develop a liquid crystal (LC)-based nitrogen dioxide monitor housing a sensor which will detect and trigger an audio-visual alarm to warn miners when the concentration of nitrogen dioxide levels exceeds the threshold limits.
• A Wearable Multivariable Sensor for NO2 and CO Detection
  5/23/2016 - Contracts and cooperative agreements
  A contract to design composite sensing materials to develop a sensor that is sensitive to carbon monoxide and nitrogen dioxide at the desired concentrations but is not affected by the interferences present in mines.
• Personal Air Safety System (PASS)
  10/11/2014 - Contracts and cooperative agreements
  A contract to provide miners with real-time alerts to potentially harmful air contaminants if a dangerous threshold of either immediate or timed exposure is detected.
• 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.
• 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.
• Nitrogen Dioxide Calibration Standards for Portable Monitors
  12/1/2005 - Information Circulars
  The purpose of this study was to compare calibration gas cylinders having balance gases of nitrogen or air that are commonly used to calibrate portable NO2 gas monitors. Because even low concentrations of NO2 can have an extremely adverse effect on ind...
• Factors Affecting Fumes Production of an Emulsion and ANFO/Emulsion Blends
  1/1/2001 - Conference papers
  Study of toxic fumes produced by the detonation of ANFO/emulsion blends. An extension of previous ANFO fumes production research that includes an emulsion blasting agent.
