In 1938, the United States Bureau of Mines began development of rules relating to the use of electricity for telephone and signaling equipment, which included application of intrinsically safe electrical circuits. 

The PAW expected private industry and the United States Bureau of Mines to capitalize on Germany s considerable experience in synthetic petroleum production. With the 30 million that Congress authorized in 1944 for a five-year synthetic petroleum...

Based on the research of Dr. E. D. Palmes (1) at New York University s Institute of Environmental Medicine and on additional study supported by a contract from the United States Bureau of Mines, a unique personal sampler has been designed to passively collect N0X. This is accomplished by way of molecular diffusion and subsequent trapping of the molecules onto a matrix coated with triethanolamine (TEA) at the closed end of the sampler. Constructed of polypropylene, the tubular sampler shown in Figure 1 is small, lightweight, unbreakable and can be easily worn in the breathing zone of the employee whose exposure is to be monitored. No pumping mechanism is required. The components of N0X diffuse at constant, known rates towards the sealed end of... 

After the firing was completed, the permanganate solution was analyzed by the same procedure used for the volatile mercury samples. Mercury in coal samples from the National Bureau of Standards and the United States Bureau of Mines were analyzed simultaneously as controls. At least duplicate analyses were performed on all samples. Empty crucibles were fired into acidic permanganate solutions by an identical procedure to obtain solutions for blank determinations. 

Table I presents the proximate and the ultimate analyses of the coals used in the study. Coals A, B, D, and E were obtained from and analyzed by the United States Bureau of Mines. The coal samples were crushed by the Bureau to pass through 60 mesh before analyzing them. The coal which passed through 60 and was retained on 100 mesh was used in this study. Coal C was obtained directly from the mine and was analyzed by the Commercial Testing and Engineering Co., Cleveland, Ohio.

Another ball mill test worth mentioning here is the USBM (United States Bureau of Mines) Ball Mill Test57 which is in some respects similar to the Bond ball mill test. The ball mill is 8 x 8 in (203 X 203 mm — diameter x length) and fitted with three lifter bars mounted longitudinally to the inside wall equally spaced around the cylinder. The charge is 100 balls one inch (25.4 mm) in diameter each and the coal charge is 500 g. The mill is rotated at 40 revs/min and a trip counter is used to count the number of revolutions completed.

The sound level experienced at a distance from an explosion can be heavily depended on transient atmospheric conditions (e.g. temperature inversions, wind shear, and even gusts of wind). The low frequency air pressure from a blast can cause vibration in buildings, in addition to its startle effect. Such vibration can give rise to concern about possible building damage at relatively low over-pressure levels. The subject has been investigated in depth by the United States Bureau of Mines, whose conclusions are summarised in [33.11].
