• Smoke Reversal Interaction with Diagonal Airway - Its Elusive Character
  1/1/2006 - Peer reviewed journal articles
  NIOSH conducted four diesel-fuel fire experiments with specific fire heat-release rates to determine the reversal of smoke products-of-combustion from a mine fire in a mine section with the airway connectivity of an electrical Wheatstone bridge.
• Snapshot of Noise and Worker Exposures in Sand and Gravel Operations
  3/1/2008 - Peer reviewed journal articles
  This paper presents research examining noise on dredges used in several surface mine sand and gravel operations and in the processing facilities.
• Solutions to Prevent Materials-Handling Injuries in Underground Coal Mines
  2/1/2007 - Peer reviewed journal articles
  This paper describes three mechanical methods - the mobile manipulator, the in-mine hoist, and a cable-handling system - developed by NIOSH to reduce injuries related to handling supplies or material, loading and unloading, and moving power cables.
• Some Relevant Parameters for Assessing Fire Hazards of Combustible Mine Materials Using Laboratory Scale Experiments
  4/1/2018 - Peer reviewed journal articles
  An article about what happens when combustible materials ignite and burn. During the processes of ignition and flaming, other life hazards present themselves and should be included to ensure an effective overall analysis of the relevant fire hazards.
• Sound Power Level Study of a Roof Bolter
  1/1/2006 - Peer reviewed journal articles
  NIOSH initiated a study of a roof bolter to reduce noise exposure to mine roof bolter operators. When drilling into granite, it was found that wet drilling generated lower sound power levels and performed better than vacuum drilling.

  2/1/2006 - Peer reviewed journal articles
  This article compares the performance characteristics of various support systems, including wood cribs, can supports, cluster props and pumpable supports.
• Status of a Tapered Element, Oscillation Microbalance-Based Continuous Respirable Coal Mine Dust Monitor
  1/1/1996 - Peer reviewed journal articles
  In response to the Mine Safety and Health Administration's request, the U.S. Bureau of Mines investigated several sensor technologies for continuously monitoring respirable coal mine dust. One of these technologies is the tapered element, oscillating m...
• Stochastic Modeling of Gob Gas Venthole Production Performances in Active and Completed Longwall Panels of Coal Mines
  11/1/2010 - Peer reviewed journal articles
  This paper describes a practical approach for implementing stochastic determination of gob gas ventholes production performances and for generalizing the prediction capability of deterministic models.
• A Study of Burnout in Accident Investigators in the US Mining Industry
  1/1/2002 - Peer reviewed journal articles
  Reports on the results of administering the Maslach Burnout Inventory assessment to 154 MSHA accident investigators.
• A Study of First Moments in Underground Mine Emergency Response
  1/1/2010 - Peer reviewed journal articles
  What happens in the first crucial moments of a mine emergency? The study showed the importance of mine emergency planning and training, communication providing information for decision-making, leadership and trust, plus individual personal issues.
