Clear; colorless or pale yellow; syrupy liquid; CH<sub>2</sub>OHCHOHCH<sub>2</sub>OH . Used in explosives, as a binder for cements and mixes, and as a lubricant and a softener; used in the manufacture of munitions and as an antifreeze liquid.
Industry:Mining
Cleavage that is closely related to the axial planes of folds in the rock, either being rigidly parallel to the axes, or diverging slightly on each flank (fan cleavage). Most axial-plane cleavage is closely related to the minor folds seen in individual outcrops, but some is merely parallel to the regional fold axes. Most axial-plane cleavage is also slaty cleavage.
Industry:Mining
Cleavage that, if studied over a large enough area, dips at different angles so that, like the ribs of a fan, it converges either upward or downward.
Industry:Mining
Clintonite found as monoclinic hexagonal-shaped prisms in metamorphosed limestone.
Industry:Mining
Closed casing in which air pressure is maintained equal to the pressures of the water and soils on the outside. The deeper the caisson, the higher the pressure that must be maintained.
Industry:Mining
Closed loop of piping, including provision for entry of material, circulation boost and controlled withdrawal points; used for circulating solids such as pulverized fuel, or fluids such as lime slurry, continuously without settlement or chokeup.
Industry:Mining
Closely spaced piles of timber, reinforced concrete, prestressed concrete, or steel driven vertically into the ground to support earth pressure, to keep water out of an excavation, and often to form an integral part of a permanent structure.
