• Impact of Air Velocity on the Detection of Fires in Conveyor Belt Haulageways
  5/1/2011 - Peer reviewed journal articles
  This paper discusses the impact of ventilation airflow on alarm times of the smoke detectors and video cameras, CO levels, smoke optical densities and smoke obscuration, total smoke mass concentrations, and fire heat release rates.
• Evaluation of Smoke Detectors for Use in Underground Mines
  2/1/2009 - Conference papers
  This report describes experiments and their results in determining the responses of a prototype smoke detector and a commercially available photoelectric smoke detector to smoke particles generated from various combustion sources.
• Fire Detection for Conveyor Belt Entries
  1/1/1991 - Reports of Investigations
  This report details the results of a series of large-scale experiments where small coal fires were used to ignite the conveyor belt at specific air velocities, and showed conditions required for early detection of conveyor belt entry fires.

• Real-time method to characterize a mine fire using atmospheric monitoring systems and MFIRE 3.0
  2/18/2020 - Research projects
  A project to provide a real-time method for determining the size and location of an underground mine fire, and the spread of smoke and toxic gases throughout the mine ventilation network, using data from atmospheric monitoring systems (AMS) and MFIRE 3.0.
• Early Fire Detection for Underground Diesel Fuel Storage Areas
  10/1/2018 - Peer reviewed journal articles
  An article presenting the results of a study investigating the responses of different sensors for early detection of diesel fuel fires in a storage area.
• Characterization of a Mine Fire Using Atmospheric Monitoring System Sensor Data
  6/1/2017 - Peer reviewed journal articles
  An article describing a NIOSH experiment that showed that the heat release rate of a mine fire can be calculated with reasonable accuracy using atmospheric monitoring systems sensor data.
• Evaluation of Detection and Response Times of Fire Sensors Using an Atmospheric Monitoring System
  3/1/2016 - Peer reviewed journal articles
  This article by NIOSH describes a series of full-scale experiments that evaluated an atmospheric monitoring system for fire detection in other areas of a coal mine.
• Evaluation of Smoke and Gas Sensor Responses for Fires of Common Mine Combustibles
  3/1/2015 - Peer reviewed journal articles
  An article detailing experiments conducted to evaluate the response characteristics of commercially available gas, smoke and flame sensors to fires of common combustible mine materials.
• Analysis of Post-Explosion Residues for Estimating Flame Travel During Coal Dust Deflagrations
  10/1/2011 - Peer reviewed journal articles
  NIOSH conducted a series of large-scale explosion experiments at the Lake Lynn Experimental Mine to investigate the inerting effect of limestone rock dust. Post-explosion dust residue samples were analyzed to infer flame travel.
