  • mining methods of the klondike gold rush

    mining methods of the klondike gold rush jump to . this could also be an alternative to shaft mining as seen on picture 2. hydraulic methods were introduced during the california gold rush and would be used later at nome. jet of water washing down a hillside, 1898 mining with sluices on hillside at klondike, 1898 hydraulic lift on discovery claim, 1898 separation methods. all methods .

  • hydraulics

    in the roman empire, different hydraulic applications were developed, including public water supplies, innumerable aqueducts, power using watermills and hydraulic mining. they were among the first to make use of the siphon to carry water across valleys, and used hushing on a large scale to prospect for and then extract metal ores.

  • hushing

    hushing is an ancient and historic mining method using a flood or torrent of water to reveal mineral veins. the method was applied in several ways, both in prospecting for ores, and for their exploitation. mineral veins are often hidden below soil and sub-soil, which must be stripped away to discover the ore veins.

  • trompe

    the presence of a trompe is a signature attribute of a catalan forge, a type of bloomery furnace. trompes can be enormous. at canadian hydro developers' ragged chute facility in new liskeard, ontario, water falls down a shaft 351 feet 107 m deep and 9 ft 2.7 m across to generate compressed air for mining equipment and ventilation.

  • quesnel forks

    the cpr also facilitated a hydraulic mining boom in the cariboo, delivering large mining equipment such as water canon and metal for pipes to ashcroft. from there, ox teams and stage coaches transported equipment and mining speculators up the cariboo road to the forks. the bullion pit mine nearby produced $1,233,936 1900 dollar value over .

  • power shovel

    power shovels are a type of rope/cable excavator, where the digging arm is controlled and powered by winches and steel ropes, rather than hydraulics like in the more common hydraulic excavators. basics parts of power shovel including the track system, cabin, cables, rack, stick, boom foot-pin, saddle block, boom, boom point sheaves and bucket.

  • mining

    the romans used hydraulic mining methods on a large scale to prospect for the veins of ore, especially a now-obsolete form of mining known as hushing. they built numerous aqueducts to supply water to the minehead. there, the water stored in large reservoirs and tanks.

  • drifter drill

    a drifter drill or drifter is a hydraulic or pneumatic rock or ground drill used to make horizontal holes in tunnel construction and mining. it is mounted on a feed, which is like a rail that the drill travels on or drifts. this kind of drilling procedure is also called drifting.

  • hydraulic fracturing by country

    massive hydraulic fracturing of gas wells in tight sandstone began in germany in 1975, and became common during the period 1978–1985, when more wells received massive hydraulic fracs in germany than in any other european country. germany also had the largest hydraulic fracturing jobs in europe, using up to 650 tonnes of proppant per well.

  • drifter drill

    a drifter drill or drifter is a hydraulic or pneumatic rock or ground drill used to make horizontal holes in tunnel construction and mining. it is mounted on a feed, which is like a rail that the drill travels on or drifts. this kind of drilling procedure is also called drifting. the feed is usually attached with a flexible boom like an arm .

  • hydraulic mining

    hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. in the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. it is also used in mining kaolin and coal.

  • hydraulics

    they used lead widely in plumbing systems for domestic and public supply, such as feeding thermae. citation needed hydraulic mining was used in the gold-fields of northern spain, which was conquered by augustus in 25 bc. the alluvial gold-mine of las medulas was one of the largest of their mines. it was worked by at least 7 long aqueducts, and the water streams were used to erode the soft deposits, and then wash the tailings for the valuable gold content.

  • hydroelectricity

    hydroelectricity would eventually supply some countries, including norway, democratic republic of the congo, paraguay and brazil, with over 85% of their electricity. the united states currently has over 2,000 hydroelectric power stations that supply 6.4% of its total electrical production output, which is 49% of its renewable electricity.
