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.
-
1/1/1991 - 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.
-
6/1/2015 - Reports of InvestigationsNIOSH researchers completed in-depth interviews with nine coal mine safety trainers about teaching and assessing Self-escape competencies (SEC). Based on the results recommendations are provided to improve training, assessment, and maintenance of SEC.

4/1/2015 - Reports of InvestigationsAn RI that explores 3 issues to facilitate use of BIP RAs: (1) locating BIP RAs further from the face; (2) providing a consistent process for the design and approval of RA stoppings; (3) delivering a reliable supply of clean, breathable air to a BIP RA.
-
2/1/1997 - Reports of InvestigationsA Report of Investigations detailing research aimed at preventing injuries and fatalities related to vertical movement of personnel and materials in mine shafts and ore passes.
-
1/1/1995 - Reports of InvestigationsDisplacement and stress changes in cemented backfill and ore pillars at the Buick Mine, near Boss, MO, were monitored by engineers from the U.S. Bureau of Mines and The Doe Run Co., St Louis, MO. Objectives of this research were to evaluate the effect ...
-
1/1/1995 - Reports of InvestigationsThis U.S. Bureau of Mines study examined spontaneous heating episodes in coal mine pillars in an active underground coal mine. The objective of this study was to discover if the location of future events of pillar spontaneous heating could be inferred ...
-
1/1/1995 - Reports of InvestigationsSubsidence data gathered by the U.S. Bureau of Mines over a series of longwall panels in the Pittsburgh Coalbed were studied to obtain insight as to the role of time in the subsidence process. These results were then compared to data from three other si...
-
1/1/1993 - Reports of InvestigationsThis report investigates the removal of gate road chain pillars in conjunction with longwall retreat mining. The objective was to determine how the pillars, supplemental support, and entries were affected by the longwall abutment pressure.
-
1/1/1993 - Reports of InvestigationsThis report presents results of a U.S. Bureau of Mines study of longwall gob material. The objective of this work was to determine material stiffness properties of the gob for use in numerical models or rock mass response to longwall mining.
