• A Study of Leakage Rates Through Mine Seals in Underground Coal Mines
  1/1/2016 - Peer reviewed journal articles
  An article detailing the results of a study on leakage rates of coal bed gas through underground coal mine seals at a western U.S. underground coal mine.
• Improving stopping construction to minimise leakage
  7/1/2012 - Peer reviewed journal articles
  The research presented in this paper investigates the total leakage of a stopping, including air leakage through the stopping, at the stopping perimeter, and through the coalbed.
• Passive Mine Blast Attenuators Constructed of Rock Rubble for Protecting Ventilation Seals
  1/1/2010 - Peer reviewed journal articles
  This paper discusses some concepts and preliminary test results for a Passive Mine Blast Attenuator (PMBA) that can provide a useful alternative to increasingly larger and stronger stand-alone mine seals.
• Clearing the Air
  5/1/2009 - Peer reviewed journal articles
  NIOSH research on reducing heavy equipment operator exposure to dust is detailed in this report.
• Use of Rocsil® Foam to Remotely Construct Mine Seals
  12/1/2008 - Peer reviewed journal articles
  This paper presents an overview of remote mine sealing technology, introduces the use of Rocsil® foam for remote mine seal installations, and offers a case study for the use of this rigid foam material to remotely construct a temporary in-mine.
• Comparison of Methods: Dynamic Versus Hydrostatic Testing of Mine Ventilation Seals
  9/1/2008 - Peer reviewed journal articles
  This paper contrasts the full-scale explosion and hydrostatic testing of mine seals using a simple dynamic system model and principles.
• Designs for Rapid in Situ Sealing
  1/1/2003 - Peer reviewed journal articles
  NIOSH, in collaboration with the Mine Safety and Health Administration, the mining industry, and seal manufacturers, conducted a series of full- scale experiments to evaluate the explosion-resistant characteristics of several new seal designs for rapid ...
• Experimental Mine and Laboratory Dust Explosion Research at NIOSH
  5/1/2000 - Peer reviewed journal articles
  Explosion characteristics such as the minimum explosible concentration and the rock dust inerting requirements were measured for various combustible dusts. The explosion resistance characteristics of seals was also evaluated.
• Inflatable Partitions for High-Expansion Foam Generators
  6/1/1995 - Peer reviewed journal articles
  The U.S. Bureau of Mines (USBM) has developed an inflatable feed-tube seal (IFTS) for high-expansion foam generators. The IFTS is a lightweight, portable, rectangular inflatable bag that can be used by firefighters to rapidly seal large openings, such a...
