摘要： In a method for introducing and blowing rock dust to bind carbon dust during advance working or coal mining using an advance working or mining machine, respectively, the cutting tools are retracted relative to a displaceable machine frame after having cut an outbreak or excavation. During the displacement of the machine frame into a new outbreak or excavation position, rock dust is blown onto the roof and lateral-wall surfaces laid bare by the cutting tools, through nozzles arranged on the machine frame by the aid of pressure medium such as compressed air. The advance working or mining machine used to carry out this method includes a displaceable machine frame and a carriage movably mounted on the machine frame and carrying a pivotable cantilever arm on which cutting heads or rolls are rotationally mounted, and a loading device intended to receive cut or broken material. At least one nozzle for atomizing rock dust is arranged on the displaceable machine frame and at least one storage bin and a compressed-air source are arranged on the advance working or mining machine.
