Hydraulic Extraction, for excavating and logistics of coal or other materials, by means of water. Hydraulic Discharge, to direct discharge of surface water from the saturated zone and drainage. Mineral Processing, for gravel and sand lifting to the drainage level in the gold mine, where the water pressure creates a powerful suction in a dump hopper and caries the gravel and sand to the
pressure. The typical hydraulic system pressure used in mining equipment is between 1000 to 5000 psig. The droplet size of a hydraulic fluid spray resulted from a rupture of hydraulic system pipelines can be in a wide range, depending on the size of the hole and the temperature of the fluid. In this study, the

The chocks were interconnected with hydraulic hoses and connected back to a pumping arrangement in the gate road by a hydraulic fluid reticulation system. The hydraulic fluid used was (and still is) mostly water with a low concentration of soluble oil, partly to assist in lubrication but mostly to inhibit corrosion.
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.
