• Pillar and Roof Span Design in Stone Mines
  1/1/2010 - Peer reviewed journal articles
  Underground stone mines in the United States use the room and pillar method of mining in relatively flat laying deposits. Roof and rib falls account for 15% of all lost time incidents. This paper presents the result of a study to improve pillar and roof...
• A Study of First Moments in Underground Mine Emergency Response
  1/1/2010 - Peer reviewed journal articles
  What happens in the first crucial moments of a mine emergency? The study showed the importance of mine emergency planning and training, communication providing information for decision-making, leadership and trust, plus individual personal issues.
• An Overview of Fundamental and Emerging Technologies to Monitor and Control Respirable Dust in Underground Coal Mines in the United States
  11/1/2009 - Conference papers
  This paper discusses a limited number of control technologies to reduce or eliminate harmful respirable dust.
• Proceedings of the International Workshop on Numerical Modeling for Underground Mine Excavation Design
  6/1/2009 - Information Circulars

  This report describes experiments, their results, and how these results apply to early-warning fire sensors capable of rapid and reliable detection of fires in atmospheres that could be contaminated by either airborne dust or diesel engine products.
• Progress Toward Improved Engineering of Seals and Sealed Areas of Coal Mines
  2/1/2009 - Conference papers
  NIOSH has initiated a seals research program with collaborators from Safety in Mines Testing and Research Station (SIMTARS) in Australia, West Virginia University (WVU), the Naval Research Laboratory (NRL), and U.S. Army Corps of Engineers (USACE).
• Understanding Mine Fire Disasters by Determining the Characteristics of Deep-Seated Fires
  2/1/2009 - Conference papers
  This paper describes the fire tests, provides insight into characteristics of flame spread, and presents the CFD modeling work results of tests to help determine the characteristics for deep-seated fires.
• Underground Coal Mining Disasters and Fatalities: United States, 1900-2006
  1/1/2009 - Historical information, Publications
  NIOSH researchers reviewed mining fatality surveillance data from the period 1900-2006, and using MSHA reports collected additional data on the deaths and circumstances associated with the Sago, Alma, and Darby incidents. They also reviewed published ma...
• Exploration of Two Position Adjustment Methods for Underground Mine Tracking Systems
  1/1/2009 - Conference papers
