PROBLEM TO BE SOLVED: To provide a rock wool air-bone construction method capable of improving an environment of a construction site, by collecting dust generated when preprocessing a raw material in a blending place of the construction site by simple equipment without requiring cost so much. SOLUTION: This rock wool air-bone construction method is characterized by collecting the dust generated in the blending place by using suction air to an air blower 3, when spraying the raw material R on a construction surface by injecting the raw material from a spray nozzle 7 together with liquids C and W, by force-feeding the raw material R to the spray nozzle 7 by the air blower 3.
