The U.S. Bureau of Mines (USBM) was the primary United States Government agency conducting scientific research and disseminating information on the extraction, processing, use, and conservation of mineral resources.
Founded on May 16, 1910, through the Organic Act (Public Law 179), USBM's missions ...
Converted into, characterized by, or resembling a breccia; esp. said of a rock structure marked by an accumulation of angular fragments, or of an ore texture showing mineral fragments without notable rounding.
Industry:Mining
Conveyor generally 50 to 300 ft (15 to 90 m) in length. It is used to transport material only from one conveyor to another.
Industry:Mining
Conveyor structure crossing the benches of open pit mines to reduce the haul distance across the pit in terrace mining operations.
Industry:Mining
Conveyor usually from 26 to 30 in (66.0 to 76.2 cm) wide and troughed so as to centralize the load and minimize spillage. A scraper feeder, consisting of an elevating chain conveyor driven by the gate belt, is often used to transfer the coal from the face belt to the gate belt.
Industry:Mining
Coolers in which atmospheric air is blown by a fan, through a nest of pipes, into a tower or chamber in which it comes into intimate contact with fine particles of water from atomizing nozzles. By the evaporation of some of this water the air rapidly becomes saturated at the wet-bulb temperature, the remaining water running off at the same temperature. This water is collected and pumped back through the nest of pipes, thereby cooling the air before it enters the spray chamber. The entering air then has a lower drybulb temperature than the atmosphere and, since its moisture content is unaltered, the wet-bulb is lower also.
Industry:Mining
Cooling from an elevated temperature in a predetermined manner to avoid hardening, cracking, or internal damage, or to produce a desired microstructure. This cooling usually follows a hot-forming operation.
Industry:Mining
Cooling of a liquid refrigerant below the condensing temperature at constant pressure.
Industry:Mining
Coordination of functional units and presentation of the results of their achievements in policy-guiding form as facts, conclusions, and recommendations. Efficient integration of the operations managed.
