Effects of Hydrotreated Vegetable Oil on Emissions of Aerosols and Gases from Light-Duty and Medium-Duty Older Technology Engines4/1/2016 - Peer reviewed journal articlesThis article by NIOSH describes a study conducted to assess the potential of hydrotreated vegetable oil renewable diesel (HVORD) as a control strategy to reduce exposure of workers to diesel aerosols and gases.
CFD Modeling of Methane Distribution at a Continuous Miner Face With Various Curtain Setback Distances7/1/2015 - Peer reviewed journal articlesA report focused on validating a series of computational fluid dynamics (CFD) models using full-scale ventilation gallery data that assessed how curtain setback distance impacted airflow patterns and methane distributions at an empty mining face.
Quantification of Optical and Physical Properties of Combustion-Generated Carbonaceous Aerosols (less than PM2.5) Using Analytical and Microscopic Techniques3/1/2015 - Peer reviewed journal articlesAn article describing experiments conducted to quantify and characterize the optical and physical properties of combustion-generated aerosols during both flaming and smoldering combustion of three materials common to underground mines.
10/1/2014 - Peer reviewed journal articlesA study assessing heavy-duty haulage trucks' contribution to the concentrations of aerosols and criteria gases in underground mine air and the physical properties of those aerosols for three FAME biodiesel blends.
Attenuation and duration of seismic signals generated from controlled methane and coal dust explosions in an underground mine12/1/2013 - Peer reviewed journal articlesSeismic monitoring provides a useful means for detection and evaluation of events resulting from mining activity.
12/1/2012 - Peer reviewed journal articlesThis study was conducted to evaluate the effects of a diesel particulate filter (DPF) regeneration process on the concentrations and size distributions of aerosols in an underground mine.
Toward developing a new occupational exposure metric approach for characterization of diesel aerosols12/1/2012 - Peer reviewed journal articlesIn this study, the current exposure metric and two additional metrics, the surface area and the total number concentration, were evaluated by conducting simultaneous measurements of diesel ultrafine aerosols in a laboratory setting.
CFD modelling of sampling locations for early detection of spontaneous combustion in long-wall gob areas1/1/2012 - Peer reviewed journal articlesIn this study, computational fluid dynamics (CFD) modeling was conducted to optimize gas sampling locations for the early detection of spontaneous heating in longwall gob areas.
9/1/2011 - Peer reviewed journal articlesThis paper presents technical and application aspects of a new software suite, MCP (Methane Control and Prediction), developed for addressing some of the methane and methane control issues in longwall coal mines.
Coal Mine Methane: A Review of Capture and Utilization Practices with Benefits to Mining Safety and to Greenhouse Gas Reduction5/1/2011 - Peer reviewed journal articlesThis article reviews the technical aspects of coal mine methane (CMM) capture in and from coal mines, the factors affecting CMM accumulations in underground coal mines, methods for capturing methane using boreholes, and borehole designs.
