• Mine Shaft Conveyance Monitoring
  10/1/2000 - Peer reviewed journal articles
  A report on technology to enhance safety during mine hoisting developed by NIOSH researchers.
• Acceleration and GPS Data Monitor Truck-Haulage Jolts
  8/1/2000 - Peer reviewed journal articles
  This paper discusses the application of global positioning system (GPS) data, accelerometers, and pressure transducers to provide feedback about equipment operations and identify the cause of truck jolts.
• Using Water Sprays to Improve Performance of a Flooded-Bed Dust Scrubber
  7/1/2000 - Peer reviewed journal articles
  Supplemental water sprays were placed along the sides of a continuous mining machine to improve suppression and confinement of the dust cloud under the cutting boom to reduce downwind dust levels. Using a full-scale mock-up of a continuous mining machi...
• Particulate Penetration of Porous Foam Used as a Low Flow Rate Respirable Dust Size Classifier
  7/1/2000 - Peer reviewed journal articles
  Because of the need to provide short-term or real-time estimates of worker respirable dust exposure, porous foam may be a viable classification media for a low flow rate, disposable respirable dust sampler for use in the coal mining industry.
• Ignition of Methane-Air Mixtures by Laser Heated Small Particles
  5/1/2000 - Peer reviewed journal articles
  Optical technologies have progressed rapidly in the past 15 years. NIOSH is conducting a study to help provide a scientific basis for developing appropriate safety guidelines for optical equipment in underground coal mines.
• Experimental Mine and Laboratory Dust Explosion Research at NIOSH
  5/1/2000 - Peer reviewed journal articles
  Explosion characteristics such as the minimum explosible concentration and the rock dust inerting requirements were measured for various combustible dusts. The explosion resistance characteristics of seals was also evaluated.
• Flammability Limit Measurements for Dusts in 20-L and 1-m3 Vessels
  5/1/2000 - Peer reviewed journal articles
  Two types of flammability limits have been measured for various dusts in the Fike 1-m3 (1000-L) chamber and in the Pittsburgh Research Laboratory (PRL) 20-L chamber.
• Overview of Dust Explosibility Characteristics
  5/1/2000 - Peer reviewed journal articles
  Provides information on the explosibility and ignitability properties of dust clouds that can be used to improve safety in industries that generate, process, use, or transport combustible dusts.
• Flammability of Gas Mixtures Containing Volatile Organic Compounds and Hydrogen
  5/1/2000 - Peer reviewed journal articles
  An experimental program was conducted to evaluate the accuracy of some current methods for predicting the flammability of gas mixtures containing hydrogen and flammable or nonflammable volatile organic compounds (VOCs) in air.
• Flammability of Methane, Propane, and Hydrogen Gases
  5/1/2000 - Peer reviewed journal articles
  This paper reports the results of flammability studies for methane, propane, hydrogen, and deuterium gases in air conducted by the Pittsburgh Research Laboratory.
