This movie is the last remaining part of footage from an old video cassette that I owned. I believe that it is still available from the Empire Mines State Park. I do not own the copyright to this movie and this is being posted here under YouTube's Guidelines for informational and teaching purposes. Then I added pictures on my own of the Malakoff State park from days gone past when mining was active in the area to the end of this movie. This is a great addition to this hydraulic mining playlist, so watch history being taught from long ago & then learn & enjoy.
Beginning with the Gold Rush era, the legacy of mining activity in California remains in water systems today. Hydraulic mining practices caused massive amounts of sediment and mercury to enter the vast network of streams and rivers that feed into San Francisco Bay. Mercury continues to pollute the watershed, making many fish toxic to consume.

Mining coal with high pressure water
Part 1 of the Hydraulic Gold Mining series. Featuring the devastation of the 1800's Hydraulic mining operations. A first hand look at an old sluice box and the Blue Lead along with some history and pictures. A great informational playlist that goes into every different aspect of hydraulic mining that I could think of. There is a lot of knowledge passed on in this 3 part series and then there are more movies added in on this playlist. If you find more movies with some new information on hydraulic mining that should be included in this playlist then let me know the url & I will add them in here for the person who has them posted :)
Jet Mining is sometimes referred to hydraulic borehole mining ("HBHM"), borehole mining ("BHM"), jet boring, underground hydraulic mining, insitu mining, borehole tin mining, jet reaming, water jet borehole mining or water jet mining. In all cases it refers to using high-pressure water or fluid to disaggregate subsurface material and concurrently using either airlift or venturi pumps to lift the disaggregated material back to surface.
Hydraulic mining, or hydraulicking, 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.Hydraulic mining originated out of ancient Roman techniques that used water to excavate soft underground deposits. ---Image-Copyright-and-Permission--- About the author(s): Henry Sandham (1842–1910) Alternative names Henry "Hy" Sandham Description Canadian painter and illustrator Date of birth/death 24 May 1842 21 June 1910 Location of birth/death Montreal, Quebec, Canada London, UK Work period 1856–1908 Work location Montreal, Boston, London Authority control VIAF: 16276438 ISNI: 0000 0001...
