• A New Leak Test Method for Enclosed Cab Filtration Systems
  5/1/2012 - Reports of Investigations
  A new test method has been developed by the National Institute for Occupational Safety and Health (NIOSH) and Clean Air Filter (CAF) for quantifying the outside air leakage into environmental cab filtration systems.
• Field Study of Longwall Coal Mine Ventilation and Bleeder Performance
  1/1/2012 - Peer reviewed journal articles
  To assess the effectiveness of commonly applied ventilation strategies for improving air distribution and ventilation controls to meet statutory requirements.
• CO and CO2 Emissions from Spontaneous Heating of Coal Under Different Ventilation Rates
  10/1/2011 - Peer reviewed journal articles
  This study evaluated CO and CO2 emissions from spontaneous heating of a U.S. coal sample in an isothermal oven under different airflow ventilation rates from 100 to 500 cm3/min. Experiments were conducted at oven temperatures of 70, 90, and 100 °C.
• The Effect of Ventilation on Spontaneous Heating of Coal
  1/1/2011 - Peer reviewed journal articles
  Study results of the role of various ventilation rates in the spontaneous heating of coal in underground mines found that there is an optimum ventilation flow to produce the maximum rate of temperature rise at the critical ambient temperature.
• Modeling the Effect of Seal Leakage on Spontaneous Heating in a Longwall Gob Area
  6/1/2010 - Conference papers
  In this NIOSH study, a computational fluid dynamics (CFD) model developed in previous work is used to model the effect of seal leakage on spontaneous heating of coal in longwall gob behind the seal.
• Continuous Miner Spray Considerations for Optimizing Scrubber Performance in Exhaust Ventilation Systems
  2/1/2010 - Conference papers
  This paper describes lab experiments to examine the effect of spray type, pressure, machine body blocking sprays, and scrubber airflow on dust and gas levels while using a 12.2 m (40 ft) exhaust ventilation curtain setback from the face.
• Degasification System Selection for U.S. Longwall Mines Using an Expert Classification System
  3/1/2009 - Peer reviewed journal articles
  This study describes the development of an expert classification system used as a decision tool which can be used for degasification system selection using site- and mine-specific conditions.
• Explosion Effects on Mine Ventilation Stoppings
  11/1/2008 - Reports of Investigations
  A joint MSHA and NIOSH study simulated actual coal mine explosion accidents to evaluate blast effects on typical U.S. mine ventilation stoppings, and presents construction and testing methods, explosion test data, and post-explosion conditions.
• Simulation of Spontaneous Heating in Longwall Gob Area with a Bleederless Ventilation System
  8/1/2008 - Peer reviewed journal articles
  To provide insights for the optimization of bleederless ventilation systems for U.S. underground coal mines, a computational fluid dynamics study was conducted to model spontaneous heating in longwall gob areas using a bleederless ventilation system.
