                                                        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 ...                             
                                                     
                        On a dredge, steel tubes pointed at the bottom and provided with lifting tackle at the top that are used to hold and to move the dredge.

									On a temperature-composition diagram, the locus of points in a system at temperatures above which solid and liquid are in equilibrium and below which the system is completely solid. In binary systems without solid solutions, it is a straight line; in binary systems with solid solutions, it is a curved line or a combination of straight and curved lines; in ternary systems, it is a flat plane or a curved surface.

									On a wagon drill, a guide to hold the starting steel in proper alignment.    
    
    						Industry:Mining    
									On account of shear strain, the longitudinal tensile or compressive bending stress in wide beam flanges diminishes with the distance from the web or webs; this stress diminution is called shear lag.    
    
    						Industry:Mining    
									On an inclined belt conveyor system, a brake that comes automatically into use in the event of power failure, thus preventing the loaded belt from running downward and piling up rock.
