Abstract: The dust content of the fully mechanized mining face is high, which is easy to seriously threaten the safety of the working face. In order to effectively control the dust pollution of the fully mechanized mining face, taking the 5202-2 fully mechanized mining face as an example, this paper analyzes the shortcomings of the existing dust removal device, and designs a high-efficiency section spray purification system HCS5-003. This system constructs a curtain fog through the application of supersonic atomization nozzles, which effectively blocks the dust of the tunneling face with the help of water mist. By installing a HCS5-003 system at 15 m, 25 m and 45 m away from the fully mechanized mining face, the 5202-2 fully mechanized mining face has achieved efficient dust removal, compared with the original dust removal measures. The total dust removal efficiency and the respirable dust removal efficiency of the working face increased by 39.4% and 41.5% respectively, achieving good dust removal effect, This study can provide reference for rapid and efficient dust removal in comprehensive excavation working faces under similar working conditions.
