5/1/2012 - Reports of InvestigationsA new test method has been developed by the National Institute for Occupational Safety and Health (NIOSH) and Clean Air Filter (CAF) for quantifying the outside air leakage into environmental cab filtration systems.
-
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.
-
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.
-
1/1/1992 - Reports of InvestigationsReports on the U.S. Bureau of Mines development and testing of an instrinsically safe methane monitor based on differential absorption of infrared light.
-
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.
-
6/1/2004 - Reports of InvestigationsA personal dust monitor (PDM) was developed to measure respirable coal mine dust mass to provide accurate exposure data at the end of a work shift.
-
4/1/2004 - Reports of InvestigationsNIOSH researchers at the Spokane Research Laboratory in Spokane, WA, are investigating the physical properties of cable bolts by replacing the conventional king wire with a modified king wire on which strain gauges have been installed.
-
5/1/1998 - Reports of InvestigationsFull-scale testing and results are described for an automated system that continuously monitors the accumulation of coal dust in mine entries.
-
5/1/1997 - Reports of InvestigationsAs the use of deep-cut mining increases, there is expected to be a greater demand for methane measurement devices capable of scanning working faces at depths in excess of 10 m to alert mine personnel of hazardous concentrations of methane and to satisfy...
-
5/1/1997 - Reports of InvestigationsA report evaluating a wireless signaling and warning system for underground mines applicable to both coal and non-coal mines. A TeleMagnetic Signalling Systems wireless ultra-low-frequency electromagnetic signaling system was installed and tested.
