2/1/2009 - Conference papersThis report describes experiments and their results in determining the responses of a prototype smoke detector and a commercially available photoelectric smoke detector to smoke particles generated from various combustion sources.
2/1/2009 - Conference papersThis paper presents the results to date of a NIOSH investigation into the possible causes that would account for the observed higher trends in CWP disease progression through review, data analysis, and in-mine surveying.
11/1/2008 - Conference papersThis article discusses how narrative-based training has evolved and is likely to continue changing in the future using the Underground Coal Mine Map Reading Training (UCMMRT) developed by NIOSH.
9/1/2008 - Conference papersThis paper summarizes recent accomplishments in a research program that is addressing mine fire prevention, detection, management, and suppression, and provides an overview of the next phase of the NIOSH mine fire research program.
Comparison of Whole-Body Vibration Exposures on Older and Newer Haulage Trucks at an Aggregate Stone Quarry Operation8/1/2008 - Conference papersThis testing monitored the performance of older and newer truck models relative to whole-body vibration (WBV) exposures as a means for determining when the vehicle (e.g., suspension system) and seats required maintenance or replacement.
7/1/2008 - Conference papersThis paper describes a seismic network installed in western Colorado in the vicinity of three underground coal mines, its features for user access to data, and then gives two examples of seismic events resulting in some damage to mine workings.
The 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.
An alternative method to the original system developed by NIOSH and Unimin Corp to provide for a stand-alone clothes cleaning system.
The Borehole Monitoring Experiment: Field Measurements of Reservoir Conditions and Responses in Longwall Panel Overburden During Active MiningThis paper describes the results of a NIOSH borehole monitoring experiment (BME) on an active longwall panel.
The results of field tests to understand how ventilation and gob characteristics affect the spontaneous heating process causing spontaneous combustion fires in longwall or worked-out gob areas are presented.
