10/5/2019 - Research projectsTo develop and evaluate technologies and approaches to improve effective dust controls to reduce respirable coal mine dust (RCMD) exposures in coal mines, focusing on reducing respirable quartz dust (RQD).
-
3/1/2019 - Peer reviewed journal articlesAn article examining the effects of spray type, operating pressure, and spray orientation on knockdown efficiencies on float coal dust for seven different water sprays.
-
12/1/2018 - Peer reviewed journal articlesAn article presenting a dimensionless empirical model developed for predicting airborne dust capture efficiency of water sprays and wet scrubbers.
-
1/1/2018An article presenting a study on the potential of open-air water sprays to reduce concentrations of airborne float coal dust, smaller than 75 µm in diameter, in longwall face airstreams.
-
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.
-
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.
-
6/1/2006 - Conference papersTests were conducted in a full-scale ventilation gallery to determine the influence of mining machine-mounted water sprays on airflows and methane concentrations at the face when blowing ventilation systems are used. Test results using different spray a...

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...
-
1/1/2006 - Peer reviewed journal articlesNIOSH recently investigated the performance of a lower-pressure, water-powered in-line series spray scrubber for removing localized airborne dust emitted at the source. Results showed noticeable improvements in airborne dust capture efficiency through ...
-
1/1/2002 - Peer reviewed journal articlesFull-scale laboratory tests provide information to longwall operators that would assist them in selecting control parameters to reduce dust levels for mine-specific conditions.
