In one form, electrical gear that allows power to be applied gently to a
stationary ball mill so as to avoid a high starting strain. The mill is
said to be inched over as it begins slowly to rotate. Pryor, 3
A unit of pressure equivalent to 0.036136 psi (248.84 Pa).
Hartman, 1
In valuation of gold lodes, the product of the width of the exposure of
ore, measured normal to the containing host rock, and the assay value in
pennyweights of a true sample of the ore, cut evenly along the measured
line. In evaluation of ore tonnages in base-metal mining, the equivalent
measurement is the assay-foot or similar convenient combination across the
exposed lode. Abbrev., in. dwt. Pryor, 3
The work done in raising 1 lb, 1 in (0.179 kg, 1 cm); a unit of work or of
energy. Abbrev., in.lb. Standard, 2
a. The rate of occurrence of accidents as determined by multiplying the
actual number of injuries in any given period by 200,000 and dividing the
product by the number of man-hours exposure. Syn:frequency rate
CFR, 1
b. A statistic used by the mining industries to measure safety performance
and compare the performance of different groups or employers. The formula
for determining the rate is: the number of injuries or illesses times
200,000 h divided by employee hours worked. The 200,000 hours represents
100 employees working 40 h/wk and 50 wk/yr. This number keeps the value
that results from the formula small. The number of employee hours comes
from company records. They represent hours worked; not vacation, sick
leave, or holiday time. Brauer
A vein discovered after the original vein on which a claim is based.
AGI
a. The angular dip of a vein, a bed, etc., measured in degrees from the
horizontal plane. Fay
b. Angle between the direction of the magnetic field and the horizontal
plane. Syn:declination
Instrument to determine the inclination of the magnetic field.
Schieferdecker
a. A shaft not vertical; usually on the dip of a vein. See also:slope
Fay
b. Any inclined plane, whether above or beneath the surface; usually
applied to self-acting planes above ground, as in the bituminous
coalfields. Fay
c. In mines, an inclined drift driven upwards at an angle from the
horizontal. Fraenkel
d. A sloping tunnel along which rails are laid from one level to another;
a mechanically worked inclined haulageway in a coal mine. CTD
e. A slanting shaft. Gordon
f. An opening driven up or down the pitch. Syn:inclined shaft
Hudson
Scot. A wheeled carriage for inclines, constructed with a horizontal
platform so that cars can be run on it and be conveyed up and down the
incline or slope. Fay
Any bedded formation of rock where the dip of the bedding planes is
greater than 10 degrees .
A type of bedding appearing commonly in sandy deposits; the strata,
essentially intraformational, dip in the direction of the current flow.
Syn:crossbedding; cross lamination; current bedding. AGI
A borehole drilled at an angle from the vertical not exceeding 45 degrees.
The drilling technique is called angle drilling. Nelson
A monocable cableway in which the track cable has a slope of about 1 in 4
over its whole length, sufficiently steep to allow the carrier to run down
under its own weight. Hammond
Drilling blastholes at an angle from the vertical. Also called angle
drilling. Woodruff
Alignment of optical extinction at some angle other than 0 degrees , 45
degrees , or 90 degrees to a crystal face or cleavage trace.
CF:extinction; extinction angle.
A fold, the axial plane of which is not vertical. AGI
A common type of gage used with the pitot tube. A straight glass tube with
connections at each end is mounted in an inclined position on an aluminum
frame, and a scale is placed under the tube. In place of water, a colored
oil is used, and the scale is graduated to read directly in inches of
water. Lewis
inclined magnetic polarization
The inclination angle of the geomagnetic field.
a. A natural or artificial slope used for facilitating the ascent,
descent, or transfer from one level to another of vehicles or other
objects. See also:incline
b. A slope used to change the direction and speed-power ratio of a force.
Nichols, 1
Polarization that is inclined to the linear dimensions of a magnetized
body, or to the plumb line or the horizon. AGI
