Hydraulic Coal Mining Article about Hydraulic Coal

In hydraulic coal mining the coal bed is broken down either by means of a high-pressure 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). The water is supplied to a stope through pipes from centrifugal pumps.
