• Effects of a diesel particulate filter regeneration process on aerosols in an underground mine
  12/1/2012 - Peer reviewed journal articles
  This 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 aerosols
  12/1/2012 - Peer reviewed journal articles
  In 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.
• Safe and Economical Inerting of Sealed Mine Areas
  9/17/2012 - Contracts and cooperative agreements
  A contract to design and construct an in-mine mobile gas generation plant to extract nitrogen gas from mine air and inject it into sealed mine areas to maintain a safe environment.
• Remote Methane Sensors
  9/17/2012 - Contracts and cooperative agreements
  A contract to integrate a micro electro mechanical system (MEMS) component into specialized electronics to measure methane levels in underground coal mines.
• CFD modelling of sampling locations for early detection of spontaneous combustion in long-wall gob areas
  1/1/2012 - Peer reviewed journal articles
  In 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.
• A New Methane Control and Prediction Software Suite for Longwall Mines
  9/1/2011 - Peer reviewed journal articles
  This 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 Reduction
  5/1/2011 - Peer reviewed journal articles
  This 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.
• Probabilistic Modeling Using Bivariate Normal Distributions for Identification of Flow and Displacement Intervals in Longwall Overburden
  1/1/2011 - Peer reviewed journal articles
  Gob gas ventholes capture methane emissions. This study used bivariate normal distributions to determine the conditional probabilities of depth-displacement, depth-flow percentage, depth-formation, and depth-gas content of the overburden formations.
• Workplace Aerosol Measurement
  1/1/2011 - Book chapters
  While approaches to workplace aerosol measurement differ; this book chapter emphasizes the basic sampling philosophies and methods used routinely in the workplace and the application of direct-reading monitors.
• Gas and Fume Generation at the Blast Site
  1/1/2011 - Book chapters
  Gases and fumes are generated as a result of explosives detonation at a blast site. This chapter discusses only those gases produced by the detonation of commercial explosives.
