Underground coal cutting tests for the purpose of monitoring respirable dust levels were performed with a boom-type mining machine in which the mechanical action of the bits was augmented by a high-pressure water jet. The respirable dust was reduced by the action of the jet to levels less than 2 mg/m3.
