Abstract: A water spray assembly especially adapted for control of dust suppression in mining machines has a manifold with one or a number of nozzles mounted thereon. The manifold provides communication between the nozzles and a manifold inlet, the manifold inlet being adapted to connect to a supply of water. The manifold cooperates with a nozzle block having a bore sized to receive at least a portion of the manifold. The block is adapted to be mounted for aiming the nozzles in a particular direction. By having the block sized to receive the manifold, the manifold being removable from the bore to facilitate replacing or cleaning the nozzles.
