• 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.
• Assessment and Application of a Single-Charge Blast Test at the Kiruna Mine, Sweden
  5/1/2011 - Peer reviewed journal articles
  Peak particle velocity (PPV) and distance measurements from a single-charge blast test conducted by Swedish researchers in iron ore at the Kiruna Mine in northern Sweden are presented.
• Underground Mine Refuge Chamber Expectations Training: Program Development and Evaluation
  3/1/2011 - Peer reviewed journal articles
  The National Institute for Occupational Safety and Health (NIOSH) developed a training program to prepare miners for what to expect psychologically and physiologically inside of a refuge chamber.
• Mine Rescue Training Facility Inventory - Compendium of Ideas to Improve US Coal Mine Rescue Training
  1/1/2011 - Peer reviewed journal articles
  This paper presents a summary of domestic and international coal mine rescue training facilities and identifies those that provide unique, real-life and/or state-of-the-art training. Research findings from this report will be used in further NIOSH inves...
• 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.
• An Analysis of Flexural Strength and Crack Width for Fiber-Reinforced Shotcrete Used in Weak Rock Mines
  1/1/2011 - Peer reviewed journal articles
  NIOSH is investigating the use of shotcrete in weak rock mass mines with the objective of reducing fatalities and injuries resulting from rock fall accidents.
• Locomotion in Restricted space: Kinematic and Electromyographic Analysis of Stoopwalking and Crawling
  1/1/2011 - Peer reviewed journal articles
  Nine participants, six males and three females, participated in a study examining kinematic and electromyographic (EMG) responses to natural cadence stoopwalking, four-point crawling (all fours), and two-point crawling (knees only).
• Noise Controls for Vibrating Screen Mechanisms
  1/1/2011 - Peer reviewed journal articles
  NIOSH is currently developing noise controls for horizontal vibrating screens.
• A Shotcrete Adhesion Test System for Mining Applications
  1/1/2011 - Peer reviewed journal articles
  NIOSH is researching safe practices for the use of shotcrete as ground support in underground mines, particularly mines operating in weak host rock; including a rugged, portable direct tensile test system for measuring shotcrete adhesion strength.
• Current trends in Reducing Ground Fall Accidents in US Coal Mines
  1/1/2011 - Peer reviewed journal articles
  In recent years, the number of some annual ground fall fatalities has approached zero, indicating that significant progress has been made. However, more progress is needed to reduce injuries caused by rock falling between supports and by rib falls.
