10/1/2009 - Conference papersThe main objective of the NIOSH research outlined in this paper was to explore the existence of visual performance improvements through the implementation of different machine mounted, lighting systems.
-
8/1/2009 - Conference papersThis paper describes network installation and methods used to collect, process, and distribute seismicity information collected on the surface above two longwall coal mines in western Colorado, and gives several examples of the collected data.
-
7/1/2009 - Conference papersThis paper presents a description of geologic settings, mining conditions, rockmass characterization with geotechnical risk assessment, analysis, mapping, and control techniques used at an underground stone mine in Central Pennsylvania.
-
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.
-
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 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.
-
2/1/2009 - Conference papersThe objective of the research described in this paper was to determine if light-emitting diodes (LEDs) improve visual performance as compared to traditional incandescent (INC) cap lamps.
