• Ignition Hazard From Internally-generated H2 in Sealed Mining Equipment
  7/1/2001 - Peer reviewed journal articles
  A number of ignition incidents involving mining and farm equipment have illustrated the surprising danger of drilling, cutting, or otherwise penetrating sealed compartments or frames that are filled with metal scrap for ballast.
• Factors Affecting the Location of Methanometers on Mining Equipment
  6/1/2001 - Conference papers
  This publication develops criteria for selecting the best machine locations for monitoring methane and gives recommendations for revising methane action levels for alternative sampling locations.
• Effects of Water Sprays and Scrubber Exhaust on Face Methane Concentrations
  6/1/2001 - Conference papers
  Research to determine how machine-mounted water sprays and a scrubber interact to reduce methane levels and what spray configurations provide the best face ventilation when used with a scrubber.
• The Modified Direct Method: A Solution for Obtaining Accurate Coal Desorption Measurements
  5/1/2001 - Conference papers
  This paper covers the development of NIOSH's modified direct method to measure the gas content of coal samples.

  5/1/2001 - Technology News
  NIOSH tech news report on an incident where CO generated from blasting at a strip mine migrated through the ground into a nearby home, poisoning the occupants.
• Effects of Water Sprays Used With a Machine-Mounted Scrubber on Face Methane Concentrations
  2/1/2001 - Conference papers
  Past studies with blowing face ventilation systems have shown that using a machine-mounted scrubber and water sprays can reduced methane levels at the face.
• Factors Affecting Fumes Production of an Emulsion and ANFO/Emulsion Blends
  1/1/2001 - Conference papers

• 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...
• 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.
