The invention relates to an arrangement for the admission of pressurized water to a spray system arranged on a powered support assembly for underground mining, having at least one spray system for plow or shearer track spraying and having at least one further spray system for goaf space spraying, canopy spraying and/or side spraying. A central water line is used for supplying water to spray nozzles of the spray systems. To increase the operating reliability of the water system and the operating security of the powered support assembly, on-off valves for the spray systems are accommodated in a spray valve block which is provided with a connection for the water line and can be arranged on the powered support assembly as a unit separated from a hydraulic valve block. The on-off valves are activated by pressure actuation and is controlled by hydraulic pressure in the water line, and each on-off vale is provided with an electronic operated control vale arranged in the spay valve block.
