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.
-
This NIOSH publication demonstrates how existing and new engineering controls can be used to reduce face methane levels.
-
11/1/2008 - Reports of InvestigationsA joint MSHA and NIOSH study simulated actual coal mine explosion accidents to evaluate blast effects on typical U.S. mine ventilation stoppings, and presents construction and testing methods, explosion test data, and post-explosion conditions.
-
11/1/2008 - Reports of InvestigationsNIOSH experimentally investigated various factor effects on cab air filtration system performance.
-
6/1/2007 - Reports of InvestigationsNIOSH studied technology and methods that could reduce accidents involving surface mining equipment. These proximity warning systems included radar, sonar, GPS, radio transceiver tags, and combinations of radar and cameras.
-
9/1/2006 - Reports of InvestigationsThis report includes the theory of operation, description, and the performance of the Personal Dust Monitor (PDM) compared to gravimetric-based reference dust sampling methods and laboratory verification of the instruments accuracy.
-
8/1/2006 - Reports of InvestigationsThis study evaluated the effectiveness of the state-of-the-art technologies for controlling DPM and gaseous emissions from underground diesel-powered mining equipment using the isolated zone approach.
-
5/1/2006 - Reports of InvestigationsAn underground metal mine study assessed the effects of diesel emissions control technologies (such as DPF systems, diesel oxidation catalytic converter, and biodiesel blends) on concentrations of diesel particulate matter and gases in mine air.
-
3/1/2004 - Reports of InvestigationsHighly stressed rock in stopes continues to be a primary safety risk for miners in underground mines because this condition can result in failures of ground that lead to both injuries and death.
-
2/1/2003 - Reports of InvestigationsNIOSH is evaluating methods to decrease accidents including one that uses devices that assist equipment operators in monitoring blind areas around the equipment to prevent collisions with workers on foot or other objects.
