1/1/1995 - Reports of InvestigationsMany mines rely on toxic gas sensors to help maintain a safe and healthy work environment. This report describes a prototype monitoring system developed by the USBM that uses light to power and communicate with remote toxic gas sensors.
-
9/1/2009 - Reports of InvestigationsThe information in this report was used by MSHA and WVOMHS&T as supporting data in their analyses and investigative reports of the Sago Mine explosion.
-
5/1/2008 - Reports of InvestigationsThis paper presents the results of the full-scale test of a composite polyurethane-aggregate seal in a hydrostatic chamber conducted by NIOSH, and provides an analysis of those results in terms of the structural behavior of the seal.
-
1/1/1995 - Reports of InvestigationsReports on a USBM study of three gel sealant systems used to minimize air ingress to areas in the mine that can undergo self-heatings and specifically mines that sustain both floor heave and self-heatings.
-
1/1/1993 - Reports of InvestigationsThe U.S. Bureau of Mines, under a Memorandum of Agreement with the American Society of Mechanical Engineers (ASME), established design criteria for a facility to melt residues from municipal waste combustion.
-
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.
-
1/1/1992 - Reports of InvestigationsThe U.S. Bureau of Mines has developed an intrinsically safe carbon monoxide (CO) monitoring system for mines by coupling a fiber-optic data telemetry system with a prototype electrochemical CO monitor.
-
1/1/1992 - Reports of InvestigationsThe performance of RETIMET metal foam as a flame arrester on explosion-proof enclosures was investigated by the U.S. Bureau of Mines both in laboratory tests and at the U.S. Mine Safety and Health Administration's (MSHA's) Approval and Certification Cen...
-
1/1/1992 - Reports of InvestigationsThe Bureau of Mines tangentially impacted potential coal-cutter bit shank materials against sandstone to investigate the potential of the materials to ignite natural gas by a friction-generated hot streak.
-
1/1/1992 - Reports of InvestigationsThe U.S. Bureau of Mines established a wire rope research laboratory to examine the factors that affect the life of wire rope. The tests indicated that once a wire rope nears the end of its service life, both deterioration and the consequent loss of ro...
