Abstract
A water system for the admission of pressurized water to spray systems 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 side spraying. A central water line feeds spray nozzles of the spray systems. To increase the operating reliability of the water system and thus of the powered support assembly, the control valves for the spray systems are accommodated in a spray valve block which is provided with a connection for the water line and which can be arranged on the powered support assembly as a unit separated from a hydraulic valve block.
