• Underground Mine Refuge Alternatives Heat Mitigation
  4/22/2020 - Peer reviewed journal articles
  An article detailing NIOSH tests on an air-conditioned borehole air supply (BAS) and a cryogenic air supply for refuge alternatives.
• Advancement of Refuge Alternatives for Underground Coal Mines
  5/9/2019 - Research projects
  A project to minimize the risk of heat illness for miners entering an RA, ensure the availability of air delivery and purging systems for RAs, facilitate the use of BIP RAs, and develop a reliable communications system for RAs.
• RA Heat Mitigation System Utilizing Advanced Liquid Air Technologies
  4/8/2019 - Contracts and cooperative agreements
  A contract to develop a heat and humidity mitigation system for refuge alternatives.
• Portable Refuge Alternatives Temperature and Humidity Tests
  1/24/2019 - Non-peer reviewed journal articles
  An article describing investigations into heat and humidity buildup in refuge alternatives.
• Estimation of Metabolic Heat Input for Refuge Alternative Thermal Testing and Simulation
  8/1/2018 - Peer reviewed journal articles
  A paper describing a study where miner size and activity level were used to determine the metabolic heat rate, oxygen requirements and carbon dioxide generation that are representative of miners in a refuge situation.
• Refuge Alternatives Relief Valve Testing and Design with Updated Test Stand
  3/1/2018 - Peer reviewed journal articles
  A study about testing relief valves in underground refuge alternatives. These spaces require an air source to supply breathable air to the occupants. A relief prevents unsafe pressures from building up inside the refuge.
• Development of Heat Mitigation Systems for Refuge Alternatives used in Underground Coal Mines
  2/1/2018 - Contracts and cooperative agreements
  A contract to develop a heat mitigation system for refuge alternatives.
• Lessons Learned from Refuge Alternative Research by NIOSH
  12/1/2017 - Non-peer reviewed journal articles
  An article describing NIOSH testing and benchmarked thermal simulation models to examine thermal conditions inside occupied refuge alternatives.
• Examination of Space/Volume Requirements for US Underground Coal Mine Refuge Alternatives
  9/1/2017 - Peer reviewed journal articles
  An article presenting a study that examined the amount of floor space needed for a person to reside inside a refuge alternative and perform basic tasks.
• Analysis of Heat Loss Mechanisms for Mobile Tent-Type Refuge Alternatives
  7/1/2017 - Conference proceedings
  This article by NIOSH describes a study in which a model was used to examine the mechanisms of heat loss from an RA to the ambient mine and the effect of mine strata composition on the final internal temperature for a mobile tent-type RA.
