• Long-Term Stability of a Backfilled Room-and-Pillar Test section at the Buick Mine, Missouri, USA
  10/1/2009 - Peer reviewed journal articles
  Instruments remaining in a test section of a lead/zinc/copper room and pillar mine where pillar mining had taken place 14 years before were read to monitor long-term stability and quantify time dependent behavior in the mine roof and backfill.
• Effects of Diesel Exhaust Aftertreatment Devices on Concentrations and Size Distribution of Aerosols in Underground Mine Air
  9/1/2009 - Peer reviewed journal articles
  This paper summarizes the results of a study conducted to evaluate the effects that several types of DPFs, DFEs, and a DOC have on the concentration and size distribution of diesel aerosols in an underground mine.
• Fall From Equipment Injuries in U.S. Mining: Identification of Specific Research Areas for Future Investigation
  9/1/2009 - Peer reviewed journal articles

• External L5-S1 Joint Moments When Lifting Wire Mesh Screen Used to Prevent Rock Falls in Underground Mines
  9/1/2009 - Peer reviewed journal articles
  This study uses biomechanical modeling to estimate external moments about L5-S1 for sixteen lifting tasks, using two sizes of wire mesh screens, and presents recommendations to reduce spine loading.
• Forecasting Gob Gas Venthole Production Performances Using Intelligent Computing Methods for Optimum Methane Control in Longwall Coal Mines
  9/1/2009 - Peer reviewed journal articles
  In this paper, the total gas flow rates and methane percentages from 10 GGVs were analyzed. The results showed that the two-hidden layer model predicted total production and the methane content of the GGVs with more than 90% accuracy.
• Technological Aspects of Solid-State and Incandescent Sources for Miner Cap Lamps
  9/1/2009 - Peer reviewed journal articles
  This paper describes the performance of LED and INC sources in cap lamps in terms of correlated color temperature, color rendering, light output, electric power, ambient temperature and air flow, and light source aging.
• Continuous Mining: A Pilot Study of the Role of Visual Attention Locations and Work Position in Underground Coal Mines
  8/1/2009 - Peer reviewed journal articles
  The purpose of this study was to perfect a method of gathering information on work positions and Visual Attention Locations needed by operators during the cutting phase and while the continuous miner trams to a new location.
• CFD Modeling of Spontaneous Heating in a Large-Scale Coal Chamber
  7/1/2009 - Peer reviewed journal articles
  This paper discusses a study in which a three-dimensional CFD modeling of spontaneous heating of coal, based on the U.S. Bureau of Mines (USBM) large-scale coal chamber tests, was conducted.
