A spraying nozzle for a cutting roller for underground mining, which is located in the vicinity of the cutting bit provided on the blade or closure ring of the roller, has a nozzle shield enclosing the nozzle and coaxially mounted therewith on the respective blade or closure ring of the roller. The nozzle shield is formed with a recess to receive the head of the nozzle and has an upper surface sloping in a direction opposite to the direction of rotation of the cutting roller to reduce wear of the nozzle shield subject to flowing abrasive mineral mined.
