Mining and Water jetting
Water jet cutting helps the mining industry work quickly and efficiently. Dating from the California Gold Rush, the use of water jet cutting or hydraulic mining, was used to blast dirt way from gold. This type of mining replaced the use of sluice boxes, pans, and tumblers. From there, pressurized water was used to blast away coal in the mines. In the 1970s, the first industrial water jet cutter was created. This achievement spurred the development of machinery used for mining diamonds of Africa. Consequences from this type of mining include ecological problems, violent back flow, large quantities of polluted water, and water blasts that mandate workers to use protective shields.
