The U.S. Bureau of Mines (USBM) was the primary United States Government agency conducting scientific research and disseminating information on the extraction, processing, use, and conservation of mineral resources.
Founded on May 16, 1910, through the Organic Act (Public Law 179), USBM's missions ...
A refraction type of seismic shooting used to facilitate the separation of intercept times into constituent delay times. Three profiles can be laid out as sides of a triangle. If intercept times are obtained at each of the vertices of the triangle from shots at the other two vertices, one can solve for the delay times at the three corners. Delay times along the 3374 sides of the triangle can be determined by taking differentials in the intercept times with respect to the delay times established at the vertices.
Industry:Mining
A refractory brick manufactured substantially or entirely of chrome ore.
Industry:Mining
A refractory material, fired or chemically bonded, consisting essentially of dead-burned magnesite; the MgO content usually exceeds 80%. Such refractories are used in the hearths and walls of basic steel furnaces, mixer furnaces, and cement kilns.
Industry:Mining
A refractory mix containing heat-resistant, hydraulic setting cement. A refractory concrete.
Industry:Mining
A refractory product, CaO.MgO, produced by calcination of dolomite or dolomitic limestone.
Industry:Mining
A refractory shape containing one or more holes through which air and other gases are introduced into a furnace.
Industry:Mining
A refractory suitable instead of porcelain and quartz glass. Powdered silicon carbide mixed with silicates and certain metals; resists acids, alkalis, and temperature shock; is not easily broken.
Industry:Mining
A refractory wall used to deflect gases or flames from the ware and to provide better heat distribution in the furnace structure.
