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.
