8/15/2012 - Information CircularsThis IC details a NIOSH investigation on the CDEM’s ability to accurately predict the explosibility of coal and rock dust mixtures. The conclusions support the field use of the CDEM to measure the explosibility of coal and rock dust mixtures.
-
1/1/2022 - Information CircularsThis report details how to implement field-based monitoring for respirable crystalline silica using portable Fourier transform infrared spectroscopy (FTIR).
-
2/1/2008 - Information CircularsThis report summarizes a field study by NIOSH that documented the reactions of 30 miners at 4 underground coal mines concerning the use of personal dust monitors (PDMs) and how they make use of the information it provides.
-
12/1/2005 - Information CircularsThe purpose of this study was to compare calibration gas cylinders having balance gases of nitrogen or air that are commonly used to calibrate portable NO2 gas monitors. Because even low concentrations of NO2 can have an extremely adverse effect on ind...
-
1/1/1995 - Information CircularsTo help evaluate the usefulness of the natural gamma radiation (NGR) technique for the coal interface detection (CID) project, the U.S. Bureau of Mines (USBM) collected data from various mining companies conducting underground and surface operations.
-
1/1/1992 - Information CircularsAn report on the evaluation of smoke detectors placed in conveyor belt entries of underground coal mines. Recommendations for performance standards, sensitivity tests, detector classification and maintenance are also presented.
-
1/1/1992 - Information CircularsA U.S. Bureau of Mines investigation of Fourier transform infrared (FTIR) spectroscopy for on-filter analysis of respirable dust.
-
1/1/1980 - Information CircularsReviews underground methane drainage programs being conducted in various coalbeds. Equipment used in drainage programs such as drills, underground pipelines, and methane monitoring systems is described.
