• Recommendations for a New Rock Dusting Standard to Prevent Coal Dust Explosions in Intake Airways
  5/1/2010 - Reports of Investigations
  This NIOSH report presents the results of extensive in-mine coal dust particle size surveys of dust samples collected from intake airways in 61 U.S. coal mines, representing all 10 MSHA bituminous Coal Mine Safety and Health Districts.
• From Scotia to Brookwood, Fatal US Underground Coal Mine Explosions Ignited in Intake Air Courses
  1/1/2009 - Peer reviewed journal articles
  NIOSH researchers studied U.S. underground coal mine explosions over a 30-year period to identify the ignition sources and locations responsible for severe explosions resulting in death, and provided recommendations for safer electrical design.
• Rock Mechanics Study of Lateral Destressing for the Advance-and-Relieve Mining Method
  8/1/2003 - Conference papers
  The advance-and-relieve method benefits from lateral destressing. Numerical modeling proved useful in studying the basic mechanics of lateral relief while investigating the sensitivity of results to different parameters using controlled experiments.
• Fire Detection for Conveyor Belt Entries
  1/1/1991 - Reports of Investigations
  This report details the results of a series of large-scale experiments where small coal fires were used to ignite the conveyor belt at specific air velocities, and showed conditions required for early detection of conveyor belt entry fires.
• A Case Study of the Stability of a Non-typical Bleeder Entry System at a U.S. Longwall Mine
  1/1/2020 - Peer reviewed journal articles
  An article detailing observations of the non-typical bleeder entries of a moderate depth longwall panel, with a primary focus on the extent and magnitude of the abutment loading.
• Deep Cover Bleeder Entry Performance and Support Loading: A Case Study
  1/24/2019 - Peer reviewed journal articles
  An article examining rear abutment extent and loading, along with how well current modeling procedures calculate those values.
• Design Concerns of Room and Pillar Retreat Panels
  1/1/2017 - Peer reviewed journal articles
