7/1/2008 - Peer reviewed journal articlesThis paper presents the results of NIOSH laboratory and field tests to evaluate the effectiveness of dust collector bags for reducing dust liberation and operator exposure from a roof bolter's dust collection system.
-
6/1/2008 - Conference papersThe objective of the research was to cost-effectively increase the air cleaning volume and improve dust capture efficiency of an off-the-shelf dust collector with a larger motor and blower.
-
10/1/2007 - Technology NewsNIOSH has investigated various cab filtration system factors on a basic HVAC system in the laboratory to evaluate their effects on overall cab dust protection performance.
-
9/1/2007 - Conference papersThis paper summarizes existing dust control technologies routinely being used in underground coal mine operations, and provides a review of new controls that are being pursued.
-
9/1/2007 - Peer reviewed journal articlesTests have been conducted by NIOSH on a newly designed device for smaller diameter drills that separates the water from the bailing air before it reaches the bit and thus provides the cost benefit of dry drilling while providing the benefit of wet drill...
-
7/1/2007 - Peer reviewed journal articlesWater spray characteristics, including droplet size and velocity, airborne dust capture potential, and induced airflow quantity for various spray nozzle designs were evaluated to provide basic information for improving spray applications.
-
4/1/2007 - Conference papersNIOSH researchers are improving protection provided by enclosed cabs on mining equipment, reducing dust generation from surface drills, reducing dust levels in iron ore operations, and developing a new method to clean dust from soiled clothes.
-
4/1/2007 - Peer reviewed journal articlesA quick, safe, and effective method has been developed that allows workers to clean their dust laden work clothing periodically throughout the day.
-
1/1/2007 - Peer reviewed journal articlesThe Thermo personal DataRam (pDR) is an instantaneous sampler that uses light-scattering technology to provide relative measures of airborne respirable dust. The pDR can be used in active and passive modes to measure respirable dust levels.
-
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...
