Hydraulic mining, use of a powerful jet of water to dislodge minerals present in unconsolidated material, including mine tailings, placer deposits, alluvium, laterites (soil rich in iron oxides), and saprolites (soil rich in clay).
In hydraulic coal mining the coal bed is broken down either by means of a highpressure water jet (5 to 10 meganewtons per sq m), which is formed by monitors, or by means of mechanohydraulic machines (mechanical breakdown of the coal with subsequent washing out by the water).
