Water furnished by destruction of pore space owing to compaction of sediments.
Industry:Mining
Water held mechanically in a soil mass and having physical properties not substantially different from those of ordinary water at the same temperature and pressure.
Industry:Mining
Water in the solid state; specif. the dense substance formed in nature by the freezing of liquid water, by the condensation of water vapor directly into ice crystals, or by the recrystallization or compaction of fallen snow. It is colorless to pale blue or greenish blue, usually white from included gas bubbles. At standard atmospheric pressure, it is formed at and has a melting point of 0 degrees C; in freezing it expands about one eleventh in volume. Ice commonly occurs in hexagonal crystals, and in large masses is classed as a rock.
Industry:Mining
Water in which salinity values range from approx. 0.50 to 17.00 parts per thousand.
Industry:Mining
Water in, or derived from, magma at the Earth's surface or at a relatively shallow level; juvenile water of volcanic origin.
Industry:Mining
Water is used for transport in some mines, esp. in placers and in claypits, and generally in mines in an elevated position and with a loose mineral. Also filling material is often transported into the mine by water. The mixture of water and solid material can also be conveyed by pumps horizontally or raised to a small height.
Industry:Mining
Water molecules completely bound into a hydrated crystal, e.g., in gypsum, CaSO<sub>4</sub>.2H<sub>2</sub>O .
Industry:Mining
Water pumped from mines usually contains impurities, some of which are in suspension, but the majority, which are soluble, cause the water to be hard. The water often contains corrosive agents, such as acids or alkalis.
