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 ...
The property of a circuit whereby self-induction occurs. It is measured by the rate of change of linkages in a circuit that accompanies a rate of change of current in that circuit of one unit per second.
Industry:Mining
The property of a fluid to offer internal resistance to flow; its internal friction. Specif., the ratio of the shear stress to the rate of shear strain.
Industry:Mining
The property of a material that enables it to undergo permanent deformation without appreciable volume change, elastic rebound, or rupture.
Industry:Mining
The property of a material to resist applied stress that would tend to distort it. A fluid has zero rigidity.
Industry:Mining
The property of a mineral to transmit light in part of the visible spectrum while being opaque in another. Compare: opaque
Industry:Mining
The property of a mud-laden fluid to resist flow due to internal friction and the combined effects of adhesion and cohesion; e.g., a Marsh funnel (used to measure the viscosity of 2077 mud) will discharge 1 quart (0.95 L) of water in about 36 s, whereas an equal volume of an average drilling mud is discharged in 40 to 55 s or more from the same funneI.
Industry:Mining
The property of an explosive by virtue of which it exerts a sharp blow or shattering effect on the material with which it is in contact. The quickest explosive of the dynamite class is the 60% straight dynamite. Quick explosives are the ones particularly desired for mudcapping. For maximum effect for this purpose, they should be of high density and sensitiveness.
Industry:Mining
The property of an igniting agent (e.g., spark, flame, or hot solid) whereby the agent can cause ignition.
Industry:Mining
The property of an ion or atom to deform so as to create a dipole from the displacement of its electron cloud.
Industry:Mining
The property of bituminous emulsions, relating to the ease with which they break when put into use. Labile emulsions are quick breaking.
