7/1/2009 - Conference papersThis paper describes a NIOSH field study to evaluate mine entries with highly moisture-sensitive roof rock for long-term stability and seasonal effects. It presents the results from the field study and the key issues determined from the study.
-
6/1/2009 - Conference papersThis paper aims to examine the effects of porosity and permeability changes of the coal seam on methane emissions in an underground continuous miner section.
-
5/1/2009 - Conference papersThis study shows a very good agreement between observations of partially burnt coal particles under a scanning electron microscopy (SEM) and floor dust samples, collected and analyzed using the alcohol coking test and SEM, to estimate flame travel.
-
3/1/2009 - Conference papersThe study objective was to compare some in vitro genotoxic activities between solvent-extraction and surfactant-dispersion preparations for a generally available diesel exhaust reference material, U.S. National Institute for Standards and Technology DPM...

2/1/2009 - Conference papersNIOSH 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).
-
2/1/2009 - Conference papersThis paper describes an inflatable temporary mine sealing technology and presents the results of NIOSH tests on the device.
-
2/1/2009 - Conference papersThis paper describes the effort to create a reliable in-mine mobile plant for extracting nitrogen gas from the mine atmosphere. The gas produced by this novel technology can be used to create an inert environment in sealed mine areas.
-
2/1/2009 - Conference papersThis paper presents a summary of domestic and international coal mine rescue training facilities and identifies those that provide unique, real-life, and/or state-of-the-art training.
-
2/1/2009 - Conference papersThe load-deformation characteristics and the load capacity of welded wire screen (roof screen) used to control ground fall were evaluated in the laboratory in a specially built test frame.
-
2/1/2009 - Conference papersThis 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.
