12/1/2006 - Peer reviewed journal articlesThis paper presents the results of NIOSH research to identify state-of-the-art bulkhead designs, including design criteria, leakage monitoring systems, and emergency warning systems.
Injuries Associated with Continuous Miners, Shuttle Cars, Load-haul-dump, and Personnel Transport in New South Wales Underground Coal Mines12/1/2006 - Peer reviewed journal articlesThis paper analyzes narrative text fields accompanying injury reports associated with continuous miners, shuttle cars, load-haul-dump vehicles, and personnel transport equipment types in New South Wales underground coal mines.
11/1/2006 - Peer reviewed journal articlesThis report summarizes the results of noise surveys, consisting of full-shift worker noise exposure, time-motion studies, and equipment noise profiling for longwall and continuous miner sections in six underground coal mines.
11/1/2006 - Peer reviewed journal articlesA method (patent pending) has been developed to determine the quality of environmental cab filtration systems. It utilizes specially configured filter cartridges to remove carbon dioxide from the ambient air with the environmental cab's air filtration s...
This article presents a perspective on coal's role in sustaining society by anchoring the message in a transparent way, including a material flow analysis, that links coal's impacts across a range of social and environmental aspects.
Effects of Trace Metals on Particulate Matter Formation in a Diesel Engine: Metal Contents from Ferrocene and Lube OilIn this study, the single particle mass spectrometer (SPMS) was applied to explore the composition of DPM, namely the origin of metals and size preferences of metals originating from metallic fuel additives and lube oil.
This article describes noise research conducted in limestone mines, detailing the equipment likely to cause worker overexposures, the occupations experiencing overexposures, and the implications for worker noise exposure reduction.
7/1/2006 - Peer reviewed journal articlesA study of the ignition of non-fire-resistant hydraulic fluid sprays was conducted by NIOSH. Both an open flame and a hot steel surface were used as the external heat sources.
6/1/2006 - Peer reviewed journal articlesRecent advances in technology have enabled the development of a small, portable, data-logging particle monitor, modified from commercial smoke alarm technology, that can meet the needs of surveys in the developing world at reasonable cost.
The Effects of Water Spray Placement for Controlling Respirable Dust and Face Methane Concentrations4/1/2006 - Peer reviewed journal articlesA series of laboratory evaluations examined the impact of water spray pressure, curtain setback distance, and external and underboom spray use for controlling respirable dust levels and sulfur hexafluoride tracer gas concentrations around a continuous m...
