3/1/2006 - Conference papersNIOSH is conducting full-scale tests at its Lake Lynn Experimental Mine to evaluate/improve remote mine seal construction technology, focusing on technology to completely close the mine opening, & reporting results from use of grout-based materials.
3/1/2005 - Peer reviewed journal articlesThis paper highlights some of the widely used standards for accurate flammability and ignitability data for chemicals, complemented with hypothetical but relevant examples describing the testing strategy, interpretation, and application of the results.
1/1/2005 - Peer reviewed journal articlesThis publication details a series of explosive detonation experiments conducted in NIOSH's Bruceton and Lake Lynn Experimental Mines to evaluate low-level (<6 psig) detonation wave propagation behavior in single- and multiple-entry configurations.
2/1/2003 - Conference papersReports on NIOSH full-scale experiments to evaluate the explosion-resistant characteristics of several new seal designs for rapid deployment during mine emergencies.
1/1/2003 - Peer reviewed journal articlesNIOSH, 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 ...
Evaluation of Explosion-Resistant Seals, Stoppings, and Overcast for Ventilation Control in Underground Coal Mining12/1/2002 - Reports of InvestigationsEvaluation of the strength characteristics and air leakage resistance of numerous innovative seal designs and ventilation control structures for use in underground coal mines.
Lightning Propagation Through the Earth and its Potential for Methane Ignitions in Abandoned Areas of Underground Coal Mines10/1/2002 - Conference papersThis paper addresses the question, 'Can lightning cause potential differences capable of igniting methane-and-air mixtures at overburden depths at which underground coal mining occurs?'
Technology News 495 - NIOSH Releases New Educational Video: Recovery of Farmington No. 9 - An Interview with Danny Kuhn3/1/2002 - Technology NewsDuring an interview, Mr Kuhn spent about two hours describing the Farmington disaster, including the workplace climate leading up to the explosion, the events that took place in the 10 days after the explosion, and the nearly 10-year effort to safely an...
Use of Ground Penetrating Radar and Schmidt Hammer Tests to Determine the Structural Integrity of a Mine Seal2/1/2002 - Conference papersOver the years, more than 20,000 mine seals have been erected in underground coal mines in the United States. The National Institute for Occupational Safety and Health is conducting research to develop design guidelines, to investigate noninvasive tech...
7/1/2001 - Peer reviewed journal articlesA number of ignition incidents involving mining and farm equipment have illustrated the surprising danger of drilling, cutting, or otherwise penetrating sealed compartments or frames that are filled with metal scrap for ballast.
