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.
-
2/1/2005 - Conference papersDescribes a small-scale field study to identify key factors that may contribute to the migration of CO through the ground.
-
8/1/2003 - Peer reviewed journal articlesLaser-based instruments are used in areas where coal dust ignition presents a safety hazard. This NIOSH study determines when an optical beam may be considered a potential ignition source in underground coal mines or coal storage facilities.
-
5/1/2000 - Peer reviewed journal articlesOptical technologies have progressed rapidly in the past 15 years. NIOSH is conducting a study to help provide a scientific basis for developing appropriate safety guidelines for optical equipment in underground coal mines.
-
3/1/1999 - Conference papersHigh-resolution hyperspectral imagery operating in the visible to shortwave infrared can help identify and map argillic zones in host rocks; these zones add a significant risk in assessing and modeling catastrophic slope movement in open-pit mines.
-
3/1/1998 - Peer reviewed journal articlesMine trailing cables operated above safe thermal limits can cause premature insulation failure, increasing electrocution and fire hazards. This paper describes an approach to measuring temperatures within reeled cable under dynamic test conditions.
-
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.
-
7/4/2023 - Contracts and cooperative agreementsA contract to provide metric analysis of dust particles collected by continuous personal dust monitor devices, which will result in useful information on dust compositions at various underground coal mines.
