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.
-
3/1/2009 - Peer reviewed journal articlesThis article is a review of recent accidents involving explosives transport both in the United States and outside of the United States.
-
2/1/2009 - Conference papersResearchers evaluated four different types of fire suppression systems to study the effect of air velocity on extinguishing conveyor belt fires. Details are presented on the large-scale fire test set-up and arrangement of fire suppression systems.
-
2/1/2009 - Conference papersThis paper describes the work NIOSH has completed in evaluating three moisture-sensitivity index tests on roof rocks from 23 U.S. coal mines.
-
1/1/2009 - Peer reviewed journal articlesNIOSH researchers studied U.S. underground coal mine explosions over a 30-year period to identify the ignition sources and locations responsible for severe explosions resulting in death, and provided recommendations for safer electrical design.
-
7/1/2008 - Peer reviewed journal articlesThis paper updates an earlier report by the authors that studied electrical injuries from 1992 to 1998. The previous information is expanded and supplemented with fatal and nonfatal injury rates and trends through 2002.
-
6/1/2008 - Conference papersThe paper provides: (a) a description of the gas pressure-based design approach to blasting, (b) a simple technique for estimating the damage radius of the buffer row of holes, and (c) a discussion of smoothwall design for the contour row of holes.
-
1/1/2008 - Peer reviewed journal articlesMoisture-sensitive roof rocks have contributed to time-dependent roof falls. NIOSH research proves the value of a wet/dry cycling test for rock evaluation.
-
1/1/2008 - Peer reviewed journal articlesThe work presented in this paper focuses on the relationship between the PDM and respirable dust concentrations currently measured by a coal mine dust personal sampler unit utilizing a 10 mm Dorr Oliver nylon cyclone.
-
7/1/2007 - Guides and manuals, Information CircularsThis report provides a sound scientific and engineering justification to recommend a three-tiered explosion pressure design criterion for new seals. The recommendations contained herein apply to new seal design and construction in U.S. coal mines.
