a. A detailed investigation of the soils at a site, including boreholes
and tests to determine their nature, thickness, strength, and depth to
bedrock. See also:site investigation; soil mechanics.
b. Geochemical prospecting term for the chemical analysis of
systematically collected samples of soil and weathered rock.
The laboratory procedure followed in examining and determining the
physical characteristics of a soil sample. Long

A process for the manufacture of high-quality killed basic Bessemer steel
in which the steel, after dephosphorization, is poured into another ladle
containing the solid components of a basic oxidizing and fluid slag.
Blowing for 30 to 40 s generates sufficient heat to promote mixing and to
avoid skull. Phosphorus contents are readily lowered and high-quality
killed steel is produced with low additional cost. Osborne
a. A homogeneous suspension or dispersion of colloidal matter in a fluid
(liquid or gas). AGI
b. A completely mobile mud. A sol is in a more fluid form than a gel.
AGI
a. A platform in a Cornish Mine shaft and esp. between a series of
ladders; a longitudinal partition forming an air passage between itself
and the roof in a mine. Usually spelled sollar or soller.
See also:sollar
b. A colloquialism used by surveyors to mean an observation on the sun.
Salt obtained by solar evaporation of seawater or other brine in shallow
lagoons or ponds.
a. To unite the surfaces of metals. Nelson
b. An alloy of uniting metals. Brazing solders are alloys of zinc and
copper, while soft solders are alloys of tin and lead Nelson
Frame set into the inside of a shaft prior to breaking through for a
heading. Stauffer
a. The under surface of a rock body or vein, esp. the bottom of a
sedimentary stratum. AGI
b. The fault plane underlying a thrust sheet. AGI
c. The middle and lower parts of the shear surface of a landslide.
AGI
d. The major fault plane over which other beds ride forward as a group
during distributive faulting.
e. The lowest thrust plane in an area of overthrusting. Commonly rocks
above are imbricated. AGI
f. The bottom of a level.
A lithographic limestone of Late Jurassic age found at Solenhofen
(Solnhofen), a village in Bavaria, West Germany. It is evenly and thinly
stratified and contains little clays. See also:lithographic limestone
AGI
A type of fumarole, the gases of which are characteristically sulfurous.
Etymol: the Solfatara volcano, Italy. AGI
Applied to a dormant or decadent stage of volcanic activity characterized
by the emission at the surface of gases and vapors of volatile substances.
a. Coal that has not been undermined, shear cut, or otherwise prepared for
blasting. Used in the expression, "shooting off the solid." Fay
b. That part of the coal that cannot be thrown out by a single shot, or
the coal beyond the loose end. Used in expressions describing holes
drilled for blasting, such as "three feet into the solid," or "on the
solid." Fay
c. Unmined; ungot. Mason
d. A rock having few open cracks, crevices, or joints and relatively
unaffected by the weakening effects of weathering. Long
e. A diamond free of cracks discernible by eye. Long
f. The rock near underground openings that stands well without artificial
support. Long
A straight-walled cylinder with or without a valve on the bottom. Used for
taking soil samples. CF:soil sampler; split-tube sampler. Long
A one-piece bushing. Nichols, 1

Material having a penetration at 77 degrees F (25 degrees C), under a load
of 100 g applied for 5 to 10 s. Urquhart
A mine car equipped with a swivel coupling and generally used with a
rotary dump. One or more cars are pulled into the rotary dump, which turns
through 180 degrees and the coal is emptied out. See also:mine car
Kentucky
Generally of either the flanged-face or the compression type. They are
used to connect two shafts to make a permanent joint and usually are
designed to be capable of transmitting the full load capacity of the
shaft. This coupling has no flexibility, either torsional, angular, or
axial, hence it is limited to those installations where rigid connections
are suitable, particularly in line shafts and extension shafts.
