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.
2/6/2015 - Contracts and cooperative agreementsA contract to develop a “smart” self-contained open circuit breathing apparatus (SCBA) that protects against threat gasses and provides an extended duration of life-sustaining oxygen inhale stream by monitoring the surrounding atmosphere.
10/11/2014 - Contracts and cooperative agreementsA contract to provide miners with real-time alerts to potentially harmful air contaminants if a dangerous threshold of either immediate or timed exposure is detected.
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.
3/4/2014 - Contracts and cooperative agreementsA contract to evaluate the role of gas desorbing on the failure of coal and the resultant influence on dynamic failures such as bumps, bursts, and outbursts.
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.
