In metal mining, one who operates the machinery that drives the haulage
cable along a power incline railway used for hauling cars, supplies,
workers, and materials to and from one level to another on a steep slope.
Also called inclined railroad operator; tramway operator. DOT
See:incline
A traverser that moves mine cars laterally and vertically by traveling on
an inclined plane. It is sometimes used at the pit bottom for the transfer
of cars from a higher decking level to a lower decking level on the
opposite side rail track. The cars are held upright in a frame and can
handle loaded or empty cars to and from the two levels.

A sensitive form of water gage, giving readings of greater accuracy. It is
used mainly for ventilation surveys. See also:water gage
Nelson
A stationary haulage engine at the top of an incline. CTD
See:angle hole
In mining, a laborer who controls the movement of cars on a self-acting
incline (loaded car going down one track pulls empty cars up on other),
hooking cable to loaded or empty cars, starting them down the incline, and
applying brake to cable drum by a lever to control their speed of descent.
Also called dilly boy; drum runner; monitor operator; plane man; wheel
runner; jinnier. DOT
In mining, a person who oils, greases, repairs, and replaces pulleys or
rollers which support the cable on a haulage slope or plane (incline)
underground and at the mine surface. Also called rolley man.
Syn:incline trackman
A shaft sunk at an inclination from the vertical, usually following the
dip of a lode. See also:turned vertical shaft; underlay shaft.
Nelson
a. An instrument for measuring the inclination or slope, as of the ground,
Syn:clinometer
b. Any of various instruments for measuring the departure of a drill hole
from the vertical; a driftmeter. AGI
c. An instrument that measures magnetic inclination. AGI
Either of the two angles formed at the station by the intersection of the
two survey lines. Mason
a. Any size fragment of another rock enclosed in an igneous rock.
Syn:xenolith
b. A particle of nonmetallic material retained in a solid metal or alloy.
Such inclusions are generally oxides, sulfides, or silicates of the host
metal, but may also be particles of refractory materials picked up from a
furnace or ladle lining.
c. A crystal, aggregate, or minute cavity filled with one or two fluid
phases and with or without a crystal phase enclosed in a host crystal.
See also:fluid inclusion; three-phase inclusion; negative crystal.
a. A term applied to crystals and anhedra of one mineral involved in
another; and to fragments of one rock inclosed in another, as when a
volcanic flow picks up portions of its conduit.
b. Particles of foreign matter, solid, liquid, or gaseous, enclosed within
a gem stone. The nature of such inclusions provides a powerful clue to the
origin of a stone and enables natural stones to be distinguished from
their synthetic counterparts. Anderson
a. The process of coal formation that begins after peat formation is
completed without there being any sharp boundary between the two
processes. From the German inkohlung. AGI
b. See:coalification
a. Said of a rock or deposit that is loose or unconsolidated. AGI
b. Said of electromagnetic radiation (EMR) having a broad spectrum of
frequencies; e.g., incoherent (sunlight) EMR vs. coherent (laser) EMR.
AGI
a. Applies to substances that will not burn. Mersereau, 2
b. Any building material that contains no matter subject to rapid
oxidation within the temperature limits of a standard fire test of not
less than 2«-h duration. Materials that continue to burn after this time
period are termed combustible. ACSG, 1
c. See:noncombustible
a. Applied to strata, a formation, a rock, or a rock structure not
combining sufficient firmness and flexibility to transmit a thrust and to
lift a load by bending; consequently, admitting only the deformation of
flowage. See also:competent
b. Soft or fragmented rocks in which an opening, such as a borehole or an
underground working place, cannot be maintained unless artificially
supported by casing, cementing, or timbering. Long
A bed that, in a particular case of folding, has yielded to the lateral
pressure by plastic adjustment and flow. This may result in the bedding
being thrown into complex structures or in the development of more regular
internal structures, particularly drag folds and fracture cleavage. The
bed tends to thicken toward the hinges, and to thin in the limbs, of the
folds. See also:competent bed
