1/1/2012 - Peer reviewed journal articlesTo assess the effectiveness of commonly applied ventilation strategies for improving air distribution and ventilation controls to meet statutory requirements.
-
5/1/2010 - Reports of InvestigationsThis 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.
-
1/1/2009 - Peer reviewed journal articlesNIOSH 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.
-
8/1/2003 - Conference papersThe 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.
-
1/1/1991 - Reports of InvestigationsThis 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.
-
1/1/2020 - Peer reviewed journal articlesAn 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.
-
1/24/2019 - Peer reviewed journal articlesAn article examining rear abutment extent and loading, along with how well current modeling procedures calculate those values.
-
1/1/2017 - Peer reviewed journal articlesA paper detailing observations made in four consecutive room and pillar retreat panels and the data collected from an instrumentation site during retreat mining.
