Separate strands of the same rope or cable used to connect two sets of
sheaves. Nichols, 1
A power shovel in which the upper works can rotate through only part of a
circle. Nichols, 1
In seismic prospecting, the person who supervises the personnel of the
crew and generally is in charge of interpretation of the data.
Dobrin
In seismic prospecting, the person who supervises the work of a field
party. Subordinate to a nonresident party chief who is responsible for the
interpretation of the data. AGI
a. In seismic prospecting, this person's function is to handle the
operational phases of the work, particularly those involving logistics and
access in difficult or remote areas, giving the party chief more time for
interpretation of the data. Dobrin
b. In gravity and magnetic prospecting, the person in charge of the
operations of a field party. AGI
Mid-Pleistocene diastrophism. AGI
The component of the pressure in a fluid in equilbrium that is due to
forces externally applied is uniform throughout the fluid.
Webster 3rd
A monoclinic mineral, Ca3 V10 O28 .17H2 O ;
forms yellow-orange to dark red-orange crusts and tiny laths; a secondary
vanadium mineral in uranium-vanadium deposits of the Colorado Plateau, and
at Minasragra, Peru.
a. An inclined opening in a mine, a raise or a winze, through which coal
or ore is delivered from a higher to a lower level. At the lower end, the
pass is normally provided with a chute or hydraulic gate through which the
material is discharged into cars or trams. See also:chute

b. A raise or winze for workers to travel in from one level to another.
Zern
c. The running of a sample through a sample divider.
d. In surface mining, a complete excavator cycle in removing overburden.
BCI
a. A cavern opening or underground tunnel having greater length than
height or width; large enough for human entrance and larger by comparison
than a lead. AGI
b. See:pass
a. The double-track part of any single-track system of transport.

a. On haulage roads, the point at which the loaded trams going outby pass
the empty trams going inby. Nelson
b. In shafts, the point at which the loaded ascending cage or skip passes
the empty descending cage or skip. Nelson
A sidetrack with switches at both ends. Kentucky
The changing of the chemically active surface of a metal to a much less
reactive state. CF:activation
A type of inhibitor that changes the electrode potential of a metal,
causing it to become more cathodic or electropositive.
passive coefficient of earth pressure
The maximum ratio of the major principal stress to the minor principal
stress. This is applicable where the soil has been compressed sufficiently
to develop an upper limiting value of the major principal stress.
ASCE
The maximum value of lateral earth pressure exerted by soil on a
structure, occurring when the soil is compressed laterally, causing its
internal shearing resistance along a potential failure surface to be
completely mobilized; the maximum resistance of a vertical earth face to
deformation by a horizontal force. CF:active earth pressure
AGI
Fault not liable to further movement. CF:active fault
Carson, 2
A metal on which an oxide film that prevents further attack on the metal
is readily formed. When a metal other than a noble metal has a high
resistance to corrosion, it is because of passivity; e.g., chromium,
nickel aluminum, tin, and various alloys. See also:passivity
CTD
passive state of plastic equilibrium
Plastic equilibrium obtained by a compression of a mass. ASCE
