Shaft timbering with cribs laid solidly upon one another.
See:noncoring bit
Drawn from hollow ingots, or otherwise, on mandrels of successively
decreasing diameters; said of certain seamless metal tubes.
Standard, 2
In diamond drilling, using a bit that grinds the whole face, without
preserving a core for sampling. Nichols, 1
These explosives are employed to a certain extent in the form of a powder
in cartridges, or as a light-running granulated mass, or as solid sticks.
They have the disadvantage that the density of charging will be small,
which means that the cost of drilling will be comparatively high.
Fraenkel
Any fuel that is a solid; such as wood, peat, lignite, bituminous, and
anthracite coals of the natural variety and the prepared varieties such
as, pulverized coal, briquettes, charcoal, and coke. Divided into two
broad classes: naturally occurring and manufactured. Newton, 1
Temperature range over which mixtures (alloys, fluxes) melt. In a
constitutional diagram, the area between liquidus and solidus.
Pryor, 3
The decrease in volume of a metal during solidification. ASM, 1
Filling a drill hole with all the explosive that can be crammed into it,
except for stemming space at top. Nichols, 1
Gr. Brit. A geological map showing the extent of solid rock, on the
assumption that all surficial deposits, other than alluvium, are absent or
removed. AGI
See:solid stowing
Any roadway driven through the solid coal seam with rib sides.
See also:narrow stall; narrow work. Nelson
Gr. Brit. Bedrock. AGI
Usually a centrifugal pump designed to resist abrasion and used for
pumping sand, gravel, fine coal, and ore tailings. Rubber linings are
generally used, which last longer than steel or iron.
See also:pulsometer
A solid fuel, such as coke, which produces comparatively no smoke when
burned in an open grate. See also:anthracite; briquette; coke.
Nelson
The extent to which one metal is capable of forming solid solutions with
another. This varies widely between different pairs of metals, some of
which are mutually soluble in all proportions, while others are
practically insoluble in each other. CTD
a. A single crystalline phase that may be varied in composition within
finite limits without the appearance of an additional phase.
Syn:mix-crystal; mixed crystal. AGI
b. Partial or total miscibility between two or more crystal structures;
e.g., ionic substitution. Syn:crystal solution
CF:isomorphous mixture; isomorphous series.
The complete filling of the waste area behind a longwall face with stone
and dirt. The packing operation may be by hand or mechanical methods,
e.g., pneumatic stowing. See also:double packing; stowing method;
strip packing. Nelson
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. AGI
The web of a steel beam consisting of a rolled section or a plate as
distinct from a lattice. Hammond
A construction of conveyor belt consisting of multiple plies of fabrics
woven into one piece, which is done on looms designed for this purpose.
Stripes are woven into the belt to show the number of plies, which range
from 2 to 10. Impregnating and coating treatments are frequently employed.
