5/17/2018 - Peer reviewed journal articlesA study using computational fluid dynamics (CFD) models to examine the effects of air-blocking shelves on airflows and respirable dust distribution associated with medium-sized surface blasthole drill shrouds as part of a dry dust collector system.
-
7/18/2016 - Contracts and cooperative agreementsA contract to design, construct, and test two new dust collection components for continuous mining operations in underground coal mines.
-
1/1/2010 - Peer reviewed journal articlesThis study tests the ability of a new air nozzle system, located under the drill deck shroud, to improve the dust capture of the drill deck shroud.

Summary of NIOSH Research Completed on Dust Control Methods for the Surface and Underground Drilling12/1/2008 - Peer reviewed journal articlesThis paper summarizes the results of research that has been done on respirable dust control for surface mine blasthole drilling operations.
-
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.
-
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.
-
2/1/2007 - Technology NewsObjective: To evaluate the effectiveness of dust collector bags for reducing dust liberation from a roof bolter dust collection system.
-
10/1/2005 - Technology NewsThis research showed that a tight shroud is very beneficial for the drill dust collection system, while improvements for a leaky shroud could be achieved with collector-to-bailing airflow ratios >= 3:1 and/or by relocating the inlet.
-
5/1/2005 - Technology NewsA new clothes-cleaning process was developed that uses a compressed air nozzle manifold to blow dust from the worker's clothes in an enclosed booth. The process cleans work clothes 10 times faster and removes up to 50% more dust than the single air hose...
